As the source factory, we have comprehensive control over the entire production chain, from product R&D, material sourcing, mold development, production, quality inspection, packaging, and shipping. This vertical integration allows us to:

3. Formula Innovation: Addressing Regulatory Upgrades and Performance Breakthroughs

Formula innovation is key to maintaining our market competitiveness, especially amidst increasingly stringent environmental regulations and evolving user demands. Every formulation adjustment must balance compliance with performance improvements.

The 2025 OEKO-TEX® STANDARD 100 introduced a new limit for bisphenol A (BPA), reducing it from 100mg/kg to 10mg/kg. This poses challenges to chain extenders (such as bisphenol A epoxy resin) in traditional Poron formulations.

To address this change, our R&D team spent eight months testing 12 alternative chain extenders.

Ultimately settling on a carboxylic acid-based hydrophilic chain extender (such as dimethylolpropionic acid, DMPA) combined with polyethylene glycol (meth)acrylate oligomers as reactive diluents.

The key to this solution lies in controlling the DMPA dosage (3-5wt%). Too low a dosage can reduce the material’s hydrolysis resistance (tensile strength loss increases from 15% to 28% after 1000 hours of hydrolysis at 77 ℉and 50% RH).

Too high a dosage can increase the material’s hardness (Shore OO hardness increases from 22 to 26), affecting comfort. Through repeated experiments, we stabilized the DMPA content at 4wt%. Simultaneously, we added 2wt% of polyethylene glycol (meth)acrylate oligomer.

Its hydrophilic groups synergize with DMPA, not only reducing the BPA content to below 5mg/kg (in compliance with the new standard) .

But also improving the material’s hydrolysis resistance by 27% (tensile strength loss after hydrolysis is reduced to 11%) through optimized molecular chain cross-linking. We also conducted accelerated aging tests on this formulation (500 hours at 158℉and 95% RH).

The results showed a rebound retention rate of 88%, significantly exceeding the 75% of conventional formulations, validating the solution’s reliability.

For esports products requiring high flame retardancy (such as public equipment in data centers and esports stadiums), we innovatively employed olefin-modified triazine-based small molecule polyamines as chain extenders, replacing traditional flame retardants (such as phosphate esters).

These chain extenders contain 20-25% nitrogen and form a dense carbon layer during combustion, preventing flame spread. Furthermore, their olefin groups cross-link with the polyurethane molecular chains, enhancing the material’s mechanical properties.

By adjusting the chain extender dosage (5-8wt%), we achieved UL94 V-0 flame retardancy for Poron (vertical burning test: self-extinguishing within 10 seconds.

No dripping igniting the cotton underneath), without compromising the material’s elasticity—the rebound rate remained above 85%, and the coefficient of friction fluctuation was ≤±2%.

This technological breakthrough has increased our market share in North America’s esports equipment market by 11 percentage points.

Customer feedback from a North American esports stadium indicates that a mouse pad using this formula showed no noticeable wear or loss of flame retardancy after a year of intensive use (12 hours per day).

4. Regional Formulation Adjustments: Adapting to Different Market Environments and Needs

Different climates and user habits across different regions around the world require targeted adjustments to the Poron formula. This regional customization capability is based on our application testing centers across three continents (Asia, Europe, and the Americas).

Each center has accumulated over 100,000 sets of environmental data (temperature, humidity, desktop material, etc.) and user operation data (mouse grip force, movement speed, etc.).

In the high temperatures above 104℉ found in the Middle East (such as Saudi Arabia and the UAE), traditional Poron materials are prone to softening and dimensional shrinkage (the dimensional change rate at 158℉ is ±2.5% over 24 hours).

Our solution is to add 2-3wt% of montmorillonite nanosheets (<1nm thick, 100-200nm in diameter) to the formula. Their layered structure hinders the thermal motion of polyurethane molecular chains, thereby improving the material's thermal stability.
X-ray diffraction (XRD) analysis revealed that the montmorillonite nanosheets were well exfoliated and dispersed within the Poron matrix, with the interlayer spacing increasing from 1.2nm to 4.5nm, forming a “nanosheet-polymer” composite network structure.

Field data showed that the Poron material containing 2.5wt% montmorillonite maintained a dimensional change within ±0.8% over 24 hours at 158℉, and maintained a 92% rebound at 122℉, significantly exceeding the 80% of the unadded material.

Field testing also took place in Riyadh, Saudi Arabia, where a mouse pad containing this formulation was placed in a non-air-conditioned esports arena (average daily temperature of 107.6℉) for three months.

The friction coefficient increased only from 0.28 to 0.30, fully meeting the requirements of daily use. The low temperatures in Nordic markets (such as Sweden and Norway) (indoor temperatures often drop below 59℉in winter) pose a challenge to maintaining the elasticity of Poron materials.

With the traditional formulation, the rebound rate drops below 70% at 14℉ resulting in a “sluggish” feel when moving the mouse.

Our adjustment plan focused on optimizing the molecular chain structure of the oligomeric diol: polybutylene adipate (PBA) with methyl side chains replaced the traditional polyethylene adipate (PEA).

The methyl side chains hinder crystallization and lower the glass transition temperature (Tg) of the material. Furthermore, the addition of 1-2wt% polypropylene glycol (PPG) as a flexible chain segment further enhances low-temperature elasticity.

Differential scanning calorimetry (DSC) testing showed that the optimized formulation’s Tg dropped from -22℉ to -49℉, while maintaining a rebound rate above 75% at 5 ℉ and a coefficient of friction fluctuation of ≤±3%.

User testing in Stockholm, Sweden, showed that mouse pads with this formulation achieved a user-friendly operating smoothness rating of 4.2 (on a 1-5 scale) in low winter temperatures, exceeding the 3.5 of conventional formulations.

To address the high humidity found in Southeast Asian markets (with an average annual humidity exceeding 80%), we added 0.5-1wt% of an organosiloxane antifungal agent (such as 3-iodopropyltriethoxysilane) to the formulation.

This agent chemically bonds with the polyurethane molecular chain, preventing the migration and loss issues associated with conventional antifungal agents.

Test data showed that this formulation achieved a Grade 0 antifungal rating (ASTM G21 standard: no visible mold growth) against Aspergillus niger and Penicillium chrysogenum.

Even after six months in a 95% relative humidity environment, the antifungal rate remained above 99%, significantly exceeding the 85% achieved with conventional formulations.

At the same time, we adjusted the isocyanate index (from 1.05 to 1.10), increased the cross-linking density of the molecular chain, and reduced the material’s water absorption rate from 3% to 1.5%, avoiding performance degradation in high humidity environments.

5. Industrial Application of Bio-Based Raw Materials: Balancing Environmental Protection and Cost

By 2025, the focus of material innovation will shift to the industrial application of bio-based raw materials, both in response to environmental protection policies and to consumer demand for sustainable products.

We collaborated with a polymer materials laboratory at a domestic university to develop a bio-based polyol based on castor oil. Through transesterification, the castor oil is hydroxylated to a hydroxyl value of 160-180 mg KOH/g, meeting the requirements for Poron synthesis.

The advantages of this bio-based polyol include its renewability—castor is an annual crop, eliminating land competition with grain production—and a 58% lower carbon footprint than petroleum-based polypropylene glycol (PPG) (Life Cycle Assessment (LCA)).

However, these polyols present challenges such as low reactivity (the hydroxyl reaction rate is 30% lower than that of petroleum-based PPG) and high viscosity (5000 mPa·s at 77℉, twice that of petroleum-based PPG).

To address these issues, we implemented two key measures. First, we adjusted the catalyst system, replacing the traditional organotin catalyst (e.g., dibutyltin dilaurate, DBTDL) with an organobismuth catalyst (e.g., bismuth isooctanoate, BiOct), with a dosage of 0.3-0.5wt%.

Organobismuth catalysts significantly increase the reaction rate between hydroxyl groups and isocyanates, reducing the foaming reaction time from 12 minutes to 8 minutes.

Furthermore, their toxicity is significantly lower than that of organotin catalysts (LD50 of 2000mg/kg compared to 200mg/kg for organotin), thus meeting environmental requirements.
Second, we added 5-8wt% propylene glycol as a diluent to reduce the viscosity of the bio-based polyol (to 2500mPa·s at 77℉), improving the uniformity of raw material mixing.

Through these optimizations, we successfully increased the proportion of bio-based polyols in our office series Poron materials to 30%.

Testing revealed a bio-based carbon content (ASTM D6866 standard) of 42%, fully meeting EU renewable material certification requirements (such as ECOCERT).

In terms of cost control, the price of bio-based polyols (approximately 18 yuan/kg) is higher than that of petroleum-based PPG (approximately 12 yuan/kg), resulting in a 15% increase in material costs.

We offset some of these costs through process optimization: First, we optimized foaming process parameters, lowering the foaming temperature from 266℉ to 257℉ and reducing energy consumption by 8%.

Second, we increased mold utilization by 12% per mold through nested typesetting.

Third, we established long-term procurement agreements with suppliers, stabilizing the purchase price of bio-based polyols below 16 yuan/kg.

Ultimately, the retail price of office mouse pads using bio-based materials increased by only 5%, far below the market expectation of 15%, achieving a balance between environmental performance and market acceptance.

In the second quarter of 2025, sales of this product series accounted for 38% of total office sales, with a repurchase rate of 35%, demonstrating consumers’ appreciation for environmentally friendly products.

6. The Art of Balancing Formulation Optimization: From Lab to Market

The 19 years of experience in formulation optimization have taught us that an excellent formulation isn’t about pursuing the pinnacle of a single performance feature, but rather finding the optimal balance between performance, cost, and environmental performance.

For example, in 2024, we received a request from a European customer for Poron mouse pads to have VOC emissions of ≤30g/L (as required by EU Regulation EC 1907/2006).

Our existing formulation at the time emitted 120g/L of VOCs, primarily from solvent-based plasticizers and residual small-molecule monomers.

The initial solution was to adopt a solvent-free formulation, completely eliminating solvent-based plasticizers and replacing them with reactive plasticizers (such as epoxidized soybean oil (ESO)).

However, testing revealed that while VOC emissions could be reduced to 25g/L, the material’s hardness increased by 15% (Shore OO hardness rose from 22 to 25), and production costs increased by 25%, far exceeding the customer’s cost tolerance (maximum increase of 10%).

We realized that simply being “solvent-free” wasn’t the best option, and we needed to strike a balance between reducing VOCs and maintaining performance and controlling costs.

Ultimately, we innovatively adopted a hybrid approach combining solvent-free in-situ polymerization with a partially reactive plasticizer.

First, we reduced the solvent-based plasticizer from 8wt% to 2wt% and replaced the traditional dibutyl phthalate (DBP) with low-volatility diisononyl phthalate (DINP), reducing VOC emissions by 70%.

Second, we introduced 3wt% of ESO as a reactive plasticizer, whose epoxy groups cross-link with the polyurethane molecular chains, compensating for the increased hardness caused by the reduced solvent content.

Third, we optimized the polymerization process, employing a step-by-step temperature increase (176℉prepolymerization followed by a 248℉ cure) to promote full reaction of the small-molecule monomers and reduce residual content.

These measures reduced VOC emissions to 28g/L, meeting customer requirements. The material hardness was maintained at 23 Shore OO, essentially the same as the traditional formulation.

Production costs increased by only 15%, and through negotiation with the customer, the end-user selling price was increased by 5%, with positive customer acceptance.
During the implementation of this solution, we also addressed a series of production challenges.

The solvent-free formula has a high viscosity (8000 mPa·s at 70℉), making it difficult to achieve uniform mixing with traditional mixing equipment. We upgraded to a high-shear emulsifier (3000 rpm) with a heating jacket (122℉) to reduce viscosity, improving mixing uniformity by 40%.

We also adjusted the mold’s venting structure to prevent bubbles generated during the foaming process, which could lead to pinholes on the product surface.

These detailed adjustments, from the lab to the production line, took three months, but ultimately enabled the industrialization of the technical solution and accumulated valuable experience for subsequent environmentally friendly formulations.

7. Conclusion:Over the past 19 years, the journey of formula optimization for Poron materials has been an evolutionary journey from “following standards” to “setting them.”

From initially referencing Rogers’ basic formula to now being able to independently develop customized formulas tailored to specific market needs,

Every parameter adjustment and every raw material substitution reflects our understanding of user needs and our commitment to pushing the boundaries of technology.

In the future, as bio-based materials and biodegradable technologies continue to develop, we will continue to explore the balance between environmental protection and performance.

Making Poron mouse pads not only a tool for enhancing user experience, but also a practitioner of sustainable development. This balanced approach is the core competitiveness that enables us, as a source factory, to survive and thrive in the fierce market competition.
