Biorenewable Ruber Anti-Degradants

During this SBIR program, Tetramer is focused on developing a biorenewable, high-performance tire rubber additive to replace 6PPD, addressing its known ecotoxicity. 6PPD is commonly used in vehicle tires as an antioxidant and antiozonant, protecting rubber from degradation due to ozone, heat, and oxygen, thereby extending tire lifespan. However, recent studies have shown that 6PPD can break down into 6PPD-quinone when exposed to ozone, a compound linked to significant environmental and health concerns, particularly its toxic effects on aquatic life. Tetramer’s materials are based on a platform of tunable biobased derivatives, that are designed to synergistically enhance the overall compatibility and performance of the biobased rubber anti-degradant for specific rubber applications. Tetramer’s biobased rubber anti-degradants offer similar or improved anti-degradant properties compared to conventional additives, including protection against ozone, UV radiation, and thermal degradation. Research and development efforts focus on ensuring that these biorenewable alternatives meet or exceed the performance standards of existing anti-degradants to ensure tire durability and safety. Biorenewable rubber anti-degradants represent a promising area of innovation in the quest for more sustainable and environmentally friendly rubber products. While challenges remain in terms of performance optimization and cost, the potential benefits in terms of reduced environmental impact and enhanced sustainability make them an attractive option for the future of the rubber industry. As research and development continue, these biorenewable alternatives may play a key role in the next generation of tire and rubber products.
