NOK Corporation Introduces New Biomass Material for Sealing Applications

In a significant step towards sustainability in manufacturing, NOK Corporation has announced the launch of a newly developed biomass material designed specifically for polyurethane sealing applications. With an impressive biomass content of 48%, this innovative polyurethane elastomer not only focuses on environmental needs but also maintains the desirable characteristics of the company's notable Iron Rubber material.

Aiming for Sustainability

Recent years have seen a marked increase in awareness surrounding carbon neutrality and environmental protection. In line with global efforts, the new polyurethane biomass material has been engineered to strike a balance between ecologically sound practices and required functionality. By substituting a portion of the petroleum-based raw materials with plant-derived polymers, NOK Corporation has succeeded in reducing CO2 emissions from production by approximately 48%. This significant reduction showcases the company’s commitment to eco-friendly production processes.

The new biomass material meets current demands for sustainable manufacturing by promoting carbon neutrality and supporting a circular economy with biodegradable hydraulic oils. These oils pair exceptionally well with the newly developed sealing components, highlighting the adaptability of NOK’s innovations in today’s environmentally conscious world.

Overcoming Technical Challenges

Creating a high-biomass polyurethane material presents distinct technical challenges, particularly concerning stability during molding and curing processes. The increased ratio of plant-based polymers often compromises the material's performance, making it difficult to achieve the desired qualities of the Iron Rubber. Moreover, the characteristics of biodegradable hydraulic oils can cause excessive swelling in sealants, leading to premature wear. NOK has adeptly addressed these challenges, ensuring that their new biomass material retains the unique properties of Iron Rubber while exhibiting necessary durability when in contact with biodegradable fluids.

Key Features of the New Material

• - Dual Focus on Environmental Performance and Basic Functions: This new material provides high biomass content while ensuring durability and sealing capabilities inherent to traditional polyurethane materials.
• - Environmental Compatibility: It is particularly suited for use in hydraulic systems that operate in environmentally sensitive areas such as forests and waterways. Utilizing biodegradable hydraulic oils in conjunction with these seals helps mitigate oil leaks, thereby minimizing environmental impact.
• - Official Recognition: The material has been certified by the Japan Organic Resources Association (JORA) with a Biomass Mark (Certification No. 250132), attesting to its eco-friendly composition.

NOK’s Broader Range of Biomass Products

In addition to their new polyurethane materials, NOK Corporation also offers various biomass-oriented products, including the Post-Corn Biomass Type (Certification No. 220348, 39% biomass content) and Biomass O-Rings (Certification No. 240090, 30% biomass content), both designed to meet the growing demand for sustainable production practices.
More information about these products can be found on the NOK product website.
