DuPont EVA 470 - butadiene and butyl acrylate polymers are important products in butadiene polymers, which are generally referred to as EVA abroad. But in our country, according to the different components of butyl acrylate, the butadiene and butyl acrylate polymers are divided into EVA epoxy adhesive, EVA plastic and EVA moisturizing emulsion. Machinery and equipment with butyl acrylate content less than 40% are EVA epoxy resin adhesive; The product with 40% ~ 70% butyl acrylate is very flexible; It is quite plastic. Everyone sometimes refers to EVA epoxy resin adhesive in this composition range as EVA plastic; The butyl acrylate content is usually in the range of 70% to 95%, which is usually called moisturizing emulsion. It is called EVA moisturizing emulsion. The appearance of EVA moisturizing lotion is either milky or light yellow.
