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.

Due to its chemical structure the ethylene vinyl acetates range. It has been developed as a powerful base adhesive offering the following unique characteristics. Eva is an elastomeric polymer that produces materials which are rubber like in softness and flexibility. 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.

Polymer products for building and construction. Strong initial adhesion high wet tack good creep resistance water alkali resistance improved thickening response and safe operation. 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. In the general formulation it can be combined with plasticizers solvents thickening agents extenders etc.

Our wide variety of base polymer emulsions for adhesives allows you to choose the exact properties required to meet specific end use requirements. 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. 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 copolymer emulsion vae emulsion is a copolymer of vinyl acetate and ethylene.

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 eva copolymers ethylene vinyl acetates are leading polymers for hot melt manufacturing due to their high versatility.
