Ethylene Vinyl Acetate Copolymer Emulsion Based Adhesive

Eva based hot melts are able to fulfill various requirements in applications such as packaging bookbinding or label sticking.

Ethylene vinyl acetate copolymer emulsion based adhesive.

This work proposed the design and fabrication method for t shaped dry adhesives based on stretchable ethylene vinyl acetate eva copolymer with strong normal adhesion strength up to 70 n cm 2. Strong initial adhesion high wet tack good creep resistance water alkali resistance improved thickening response and safe operation. Vinyl acetate ethylene copolymer emulsion vae emulsion is a copolymer of vinyl acetate and ethylene. Due to its chemical structure the ethylene vinyl acetates range.

Vinyl acetate ethylene vae copolymers are water based emulsions that offer considerable performance advantages over polyvinyl acetate pva homopolymer adhesive glue due to the ability to alter their glass transition temperature tg c through the incorporation of ethylene monomer. Vinyl acetate ethylene vae emulsions are based on the copolymerization of vinyl acetate and ethylene in which the vinyl acetate content can range between 60 and 95 percent and the ethylene content ranges between 5 and 40 percent of the total formulation. Eva is an elastomeric polymer that produces materials which are rubber like in softness and flexibility. A water based contact adhesive composition especially suited for high modulus laminates subjected to high temperature post forming com prising an aqueous medium containing 45 to 85 wt adhesive component consisting essentially of a 50 99 wt vinyl acetate ethylene emulsion copolymer of 10 50 wt toluene insolubles and 20 to 10 c tg and preferably prepared by the emulsion polymerization.

Ethylene vinyl acetate emulsion eva emulsion is a general purpose copolymer water based emulsion that can be used in the film bonding paper bonding floor wall and ceiling adhesive. It has been developed as a powerful base adhesive offering the following unique characteristics. We offer a full line of acrylic vinyl acrylic styrene acrylic vinyl acetate and vinyl acetate ethylene copolymer emulsions. Fuller s full line of acrylic vinyl acrylic styrene acrylic vinyl acetate and vinyl acetate ethylene copolymer emulsions you will take your general purpose polymer adhesive heat seal wood assembly specialty adhesive and pressure sensitive applications to the next level.

The eva copolymer which is based on a high proportion of va greater than 60 is referred to as ethylene vinyl acetate rubber. Ethylene vinyl acetate eva copolymers ethylene vinyl acetates are leading polymers for hot melt manufacturing due to their high versatility.
