Introduction

Ethylene-vinyl acetate copolymer (EVA) is obtained by copolymerizing ethylene and vinyl acetate in different proportions. The E in the English abbreviation of EVA stands for ethylene, and VA stands for vinyl acetate. Its performance is similar to that of vinyl acetate (VA). The content is closely related, and can be divided into three categories according to the different VA content: VA content is 5%-40% called EVA plastic, mainly used for polyethylene modification, manufacturing wire and cable, film and other molding products and mixtures; VA The content of 40%-90% is called EVA rubber, which is mainly used in rubber, cable and automotive industry parts; the content of VA is higher than 90%, called polyvinyl acetate emulsion, which is mainly used for adhesives, coatings, etc.

Chemical properties

Use

●  Ethylene-vinyl acetate copolymer can be used in the production of various films, foam products, hot melt adhesives and polymer modifiers; it can also be used in the preparation of coatings, adhesives, and in the finishing of interior and exterior walls of buildings.

Production method

●  Dust evenly and heat press.

●  Ethylene-vinyl acetate copolymers of various molecular weights can be obtained by high pressure free radical polymerization, bulk continuous polymerization or solution polymerization.
