This article systematically analyzes the technological breakthroughs, performance, and industrialization path of bio-based Poron materials.

Revealing the cost challenges and market opportunities faced in the environmental transition and providing a reference for sustainable development in the industry.

1. Technical Pathways and Raw Material Innovations for Bio-Based Materials

The core breakthrough of bio-based Poron materials lies in their efficient substitution for renewable raw materials. Traditional Poron is primarily made from petroleum-derived MDI (methylene diphenyl diisocyanate) and polyether polyols.

Bio-based versions achieve green transformation through two technical approaches: partial substitution, replacing 30-50% of the polyether polyol with plant-based polyols (such as castor oil and soybean oil derivatives).

And full bio-based production, combining bio-based MDI with plant-based polyols, with the current maximum bio-based content reaching 72%.

Rogers Corporation’s RenewPoron series, launched in 2025, uses castor oil-based polyols, which reduce its carbon footprint by 58% compared to traditional products and have been certified under the EU Environmental Product Declaration (EPD).

The characteristics of the raw materials place special demands on the foaming process. The molecular structure of plant-based polyols differs from that of petroleum-based polyols, resulting in different reactivity and viscosity properties.

Traditional foaming processes can lead to problems such as uneven bubble distribution and density fluctuations.

The solution includes developing a specialized catalyst system to precisely control the reaction induction period to 45-60 seconds; employing supercritical CO₂ foaming technology to achieve uniform bubble distribution with a diameter of 10-50μm.

And optimizing the stirring rate (800-1200rpm) and temperature profile (45-65°C stepwise control). Data from a pilot plant showed that after process optimization, the density deviation of bio-based Poron was reduced from ±8% to ±3%, meeting industrial application standards.

Performance compensation technology overcomes the contradiction between environmental protection and user experience. Initial bio-based Poron products suffered from insufficient rebound resilience (15% lower than traditional ones) and poor water resistance.

These breakthroughs were achieved through three technological innovations: first, the introduction of a nanocellulose reinforcement phase; a 3-5% addition can increase rebound by 12%; second, modification with a silane coupling agent reduces water absorption from 8% to 3.5%.

And third, the development of a gradient foam structure with a surface density of 0.45g/cm³ for abrasion resistance and an inner layer of 0.3g/cm³ for cushioning.

The optimized bio-based product achieved an 85% rebound performance in compression tests, approaching the 88% achieved by traditional Poron.

Localization of the raw material supply system. To reduce cost fluctuations, the bio-based Poron industry chain has begun establishing a regional raw material supply network: in Southeast Asia, leveraging the palm oil industry to develop polyol production.

In North America, leveraging soybean cultivation to establish a supply base; and in China, exploring technologies to convert waste cooking oil into a resource.

A domestic company’s waste cooking oil-based polyol project reduced raw material costs by 22% and achieved a 62% reduction in carbon emissions per ton, supplementing profits with carbon trading revenue.

2. Performance and Application Scenario Verification

Bio-based Poron achieves similar core performance indicators to traditional materials. Laboratory test data shows that high-quality bio-based products can achieve a Shore OO hardness of 25-30, comparable to traditional Poron.

Compression set (70°C x 22h) is 8%, slightly higher than the 5% of traditional products but still significantly better than EVA’s 25%. Tensile strength reaches 1.5 MPa, meeting the durability requirements of mouse pads.

In a six-month accelerated aging test, the performance retention rate of bio-based Poron was 82%, compared to 85% for traditional products, further narrowing the gap.

Professional-level verification for esports applications has achieved a breakthrough. Professional player tests show that the nano-enhanced bio-based Poron mouse pad has an aiming accuracy error of ±2.5% in CS:GO, only 0.5 percentage points higher than traditional Poron.

The change in surface friction coefficient after four hours of continuous operation is 3%, comparable to traditional products.

Field data from one team shows that the headshot rate using a bio-based mouse pad decreases by less than 2% compared to traditional products, which is well within the acceptable range.

The environmental premium in the office is gaining recognition. Corporate procurement data shows that FSC-certified bio-based Poron mouse pads, while priced 15-20% higher per unit, have a penetration rate of 37% among tech companies with high ESG scores.

User feedback indicates that 92% of office users cannot distinguish bio-based from traditional products by feel, but when informed of their environmentally friendly properties, 81% are willing to pay a premium.

A procurement case study from an internet company shows that equipping all employees with bio-based mouse pads reduced annual carbon emissions by 12 tons, contributing to an improvement in its ESG rating.

Adaptability tests in extreme environments. At -10°C, the hardness of bio-based Poron increased by 15%, slightly higher than the 10% of conventional products. However, this increase could be improved to 12% by adding a cold-resistant plasticizer.

In a 90% humidity environment, the weight of the moisture-resistant bio-based product increased by 3.8%, surpassing the 5.2% of the untreated conventional product.

In field tests in tropical regions, the bio-based mouse pad achieved a mold resistance rating of 0 (no growth), meeting the needs of the Southeast Asian market.

The advantages of longevity and recyclability are evident. Cycling tests showed that after 10,000 compression cycles, the elasticity loss of bio-based Poron was 12%, superior to the 15% of conventional products.

In waste disposal, the bio-based material achieved a 92% degradation rate in 180 days under industrial composting conditions, compared to only 15% for conventional Poron.

Even more valuable is its chemical recyclability: 85% of the polyol can be recovered through alcoholysis, achieving a closed-loop recycling process.

3. Industrialization Challenges and Cost Optimization Paths

High costs are the primary obstacle to the widespread adoption of bio-based Poron. Currently, the production cost of bio-based Poron is 35-50% higher than traditional materials, primarily due to three factors: the price of plant-based polyols is 25% higher than petroleum-based polyols.

Modified additives add 15% to the cost; and small production scale leads to high unit energy consumption. Cost structure analysis shows that when the proportion of bio-based materials exceeds 30%, economies of scale begin to emerge, and unit costs can be reduced by 18%.

One company’s expansion plan shows that increasing production capacity from 500 tons/year to 2,000 tons/year will reduce unit costs by 27%.

Process optimization continues to explore cost reduction opportunities. Integrated reactive extrusion technology has shortened the production process from six steps to three, reducing energy consumption by 32%.

Using continuous foaming equipment instead of batch production has increased efficiency by 45%. The development of multifunctional additives has reduced the number of additives from five to two, reducing costs by 12%.

By combining these measures, one manufacturer successfully kept the cost premium for bio-based Poron below 20%, creating conditions for mass market adoption.

Policy dividends alleviate cost pressures. Companies can reduce the costs of environmental transformation through various policy tools: applying for special green manufacturing subsidies, which cover 15-30% of R&D investment; participating in the carbon trading market.

Where carbon emissions reductions from bio-based materials can generate additional revenue; and leveraging tax incentives for environmentally friendly products, which can reduce the value-added tax rate from 13% to 9%.

Data from a listed company shows that policy support can reduce the overall cost of bio-based products by 12-18%, significantly improving profitability.

Differentiated pricing strategies for application scenarios. Tiered pricing is implemented for different markets: in the high-end esports market, bio-based Poron mouse pads remain competitive even at a 30% premium; in the corporate procurement market, the premium is kept below 15%.

And in the mass consumer market, the premium is reduced to below 10% by simplifying the formula. This differentiated strategy has enabled the overall gross profit margin of bio-based products to remain above 35%, higher than the 28% for traditional products.
