- Product Introduction
Over View
ACM2311C is one crosslinking polyacrylate rubber, which is formed by emulsion polymerization of acrylate monomer and special cross-linked monomer. lt has excellent aging resistance, oil resistance, high temperature resistance, and ozone resistance. The Tg of ACM2311C is -18 ℃, with fast curing, low compression set, slight mold contamination. lt is suitable for molded products, adhesive etc., widely used in automobiles, motorcycles, ships, electric power etc. As a benchmark product of 4051, ACM2311C is better than 4051 in almost all indicators, but the price is only two-thirds of the latter. With good product quality and extremely competitive price, 2311C has gained a good reputation in the industry.
