Ethylene vinyl acetate copolymer resin.

In addition poly vinyl acetate ethylene vae copolymers possess enhanced toughness flexibility and serviceability. Ethylene vinyl acetate copolymer eva properties and applications. On a weight basis ethylene is far more effective a fact that is reflected in the low tg of polyethylene homopolymer below 80 c. Ethylene vinyl acetate copolymer eva ethylene vinyl acetate eva is the copolymer of ethylene and vinyl acetate.

Having outstanding clarity gloss and weather resistance our nipoflex resins offer flexibility over wide temperature ranges as well as high impact strength elasticity and resistance to flex and environmental stress cracking. Also it imparts plastic like properties that enable wax to compete effectively with high quality polymeric coatings. Ethylene vinyl acetate eva also known as poly ethylene vinyl acetate peva is the copolymer of ethylene and vinyl acetate the weight percent of vinyl acetate usually varies from 10 to 40 with the remainder being ethylene. Eva ethylene vinyl acetate this copolymer resin can be used in adhesives sealants and coatings.

Ethylene vinyl acetate eva is a random copolymer of ethylene and varying amounts of vinyl acetate va. Chemical formula diagram. These material are used when a combination of softness toughness flexibility and polarity are needed. There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used.

Eva offers good bondability and adhesion to polar substrates in extrusion coating and multi layer film applications. Ethylene vinyl acetate eva copolymer resins. Eva copolymers are used in molded caps and seals footwear and car interiors. Ethylene vinyl acetate or eva is a copolymer of ethylene and vinyl acetate with a structure as shown below.

As the va content increases crystallinity decreases until at 50 the eva is. Both effects result in a lowering of the tg of the final copolymer. Ethylene vinyl acetate eva copolymers are used in extrusion film processes for applications including packaging surface protection and greenhouse covers and in photovoltaic cell encapsulation. Resin for packaging adhesives film forming and molding resins hot.

Relevant identified uses of the substance or mixture and uses advised against. It is an extremely elastic and tough thermoplastic of excellent clarity and gloss and with little odor. Ethylene vinyl acetate eva copolymer cas no. Emblem in packaging technology 2012.
