Peroxide cured HNBR/Methacrylate blends with improved low temperature performance (Paper No. 30)

摘要

Hydrogenated Nitrile Butadiene Rubber (HNBR) zinc dimethacrylate (ZDMA) blends have been available for many years now and the improved mechanical properties that are offered are well recognised within certain areas of the rubber industry, such as belting, roller covering and the oil industry. It is also understood that HNBR terpolymers, which offer improved low temperature performance also provide lower mechanical strength, when compared to copolymer grades of HNBR. The incorporation of methacrylate reinforcement technology in HNBR terpolymers has the potential to offer a material with excellent mechanical, thermal and chemical resistance properties. This material has potential for application not only in the automotive industry but also in the oil industry and other areas where elastomers fail due to the arduous nature of their service environment. This work studies the phenomenon of significantly enhanced mechanical strength that occurs when HNBR elastomers are correctly blended with methacrylate additives and how this technology can be applied to HNBR elastomers with improved low temperature performance. It will review the basic reinforcement mechanism that occurs within the HNBR/ZDMA blend, typical laboratory test data and how this technology can be translated into practical applications for these HNBR based materials.
