Acrylate rubber seal performance and composition

The main reason for the rubber seals are a problem: the problem of raw materials, storage problems of the seal, the seal structure design problem, choose the seal, the seal assembly, hydraulic system contamination and the use of acrylate rubber rubber comonomer seals can be divided into three categories based monomers monomers, low oil monomer and a cure site monomer.

Acrylate rubber rubber seals main monomer, commonly used main monomers are methyl acrylate, ethyl acrylate, butyl acrylate and 2-ethylhexyl acrylate and the like; ester side with the increase of carbon number, increase the degree of cold , but the oil is deteriorated, ACM in order to maintain good oil resistance, and to improve its low temperature performance, low temperature synthesis of some oil will monomer having a polar group.

Rubber seals low temperature oil acrylate rubber monomers, using conventional acrylate esters copolymerized alkoxy ether to give ACM cold temperature of -30 deg.] C; thereafter industrial production of rubber seals and selection methoxyethyl acrylate comonomer production of cold-type ACM, to further reduce the temperature.

    Acrylate rubber is widely used in high-temperature, heat-resistant oil products. Due to the poor resistance of silicone rubber, nitrile rubber low heat resistance, oil resistance and heat resistance in terms of overall performance, fluorine rubber, acrylic rubber behind, ranked second in the raw rubber varieties, are manufactured using high temperature at 180 ? rubber seals, O-rings, gaskets and hoses suitable material. In the conditions of use are not very demanding, but with lower fluorine rubber uneconomical situation, acrylate rubber can be selected.
