Nipol AR12 Polyacrylate Zeon Chemical Rubber - Elastomer >> Polyacrylic Rubber SEALANT >> Pre-formed tape / Gasket Zeon Chemicals announced at the American Chemical Society, Rubber Division Meeting in October 2001 that it has commercialized a new low-temperature polyacrylate (ACM) elastomer – Nipol® AR12. Polymerized using newly developed curesite technology, Nipol AR12 provides significant improvements in compression set, sealing force retention, and long-term physical property retention versus traditional polyacrylates and ethylene-acrylates (AEM).. As this polymer contains the same curesite as that of Nipol AR14 and AR22, as well as that of AEM, it can be easily blended with any of these polymers to give the best balance of heat, oil resistance and low temperature resistance. Zeon Chemicals announced at the 158th meeting of the American Chemical Society, Rubber Division that is has commercialized a new low-temperature polyacrylate (ACM) elastomer – Nipol® AR12. Polymerized using newly developed curesite technology, Nipol AR12 provides significant improvements in compression set, sealing force retention, and long-term physical property retention versus traditional polyacrylates and ethylene-acrylates (AEM). At 150°C, Nipol AR12 has shown to retain sealing force in excess of 4000 hrs in SF-105 synthetic oil while swelling less than 15%. Nipol AR12 is ideally suited for injection and compression molded automotive parts including engine and transmission seals and gaskets. Nipol AR12 acrylic elastomer contains one or more acrylic esters with a small percentage of a chlorine reactive cure site. Vulcanizates have excellent oil, heat and compression resistance. Polyacrylate elastomer containing one or more acrylic esters. Provides heat, oil and low temperature resistance, good compression set, sealing force retention, and long-term physical property retention. Used in automotive parts including engine and transmission seals and gaskets.
