[Case Study] Rubber Product Issues: Softening and Deterioration of Rubber
We will introduce a case study that significantly reduces the risk of softening deterioration by implementing a second bridge.
The popular rubber material known for its excellent weather resistance and ozone resistance is EPDM. However, in recent years, with the development of sulfur-free options, there have been cases where peroxide-crosslinked EPDM, which is widely used, can experience a softening degradation phenomenon, melting like candy when used for long periods in high ozone concentration environments. For peroxide-crosslinked EPDM, it is possible to significantly reduce the risk of softening degradation by implementing secondary crosslinking to remove residual peroxides. Our company accepts consultations regarding market complaints and material issues related to customer products, and we develop and propose new formulations as countermeasures, ensuring the supply of safe and reliable rubber parts. Please feel free to contact us when needed. 【Solutions】 ■ For peroxide-crosslinked EPDM, implementing secondary crosslinking can remove residual peroxides and significantly reduce the risk of softening degradation. ■ If there are concerns about softening degradation due to hydrolysis of urethane rubber, selecting ether-based urethane rubber can mitigate the risk of hydrolysis. *For more details, please feel free to contact us.
