Zeon Chemicals (Louisville, KY) has enhanced its low-temperature hydrogenated nitrile rubber (HNBR) to meet the needs of oil, energy, automotive, aerospace, and industrial environments. Zetpol 4310 HNBR provides low-temperature performance, mechanical properties, and improved processability, while also yielding high-temperature resistance not previously attainable with these materials. Compared to earlier-generation HNBRs, Zetpol 4310 has better processability, improved low-temperature tensile strength, reduced compression set, and improved retention of properties after aging.
