Ethylene Vinyl Acetate Copolymer Emulsion

Pvac copolymer emulsion glue of vinyl acetate vam and acrylic acid vaa polyacrylamide copolymer used as flocculation agent in water treatment polymethyl methacrylate is the clear break resistant sheeting sold as acrylic glass or simply acrylic sheet or under the trade name plexiglas perspex etc.

Ethylene vinyl acetate copolymer emulsion. 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. The synthesis method comprises the processes of pre emulsification emulsion polymerization reaction finishing and defoaming. Ethylene vinyl acetate emulsion. Polymerization leads to vae copolymers.

There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used. Vinyl acetate ethylene vae emulsion celanese emulsion polymers is a global leader in vinyl acetate ethylene vae emulsions. Sumielite series is a product line of water based emulsions composed of ethylene vinyl chloride copolymer. 52 the low odor performance is partially attributed to factors such as the structure composition properties of the vinyl acetate ethylene copolymer emulsion and its advantages over commonly used styrene butadiene copolymer emulsion.

In contrast to the emulsion polymerization of vinyl acetate the syntheses of vinyl acetate ethylene copolymers utilize high pressure reactions ranging from 20 to 60 bar or even more. 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. Vae copolymers form the basis for engineering different properties in the individual end application. We manufacture these high performance emulsions in all three major regions of the world at our facilities throughout north america europe and asia.

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. Vinyl acetate ethylene vae is a combination of ethylene and vinyl acetate two monomers possessing special properties as e g. The invention relates to vinyl acetate ethylene copolymer emulsion vae emulsion and a synthesis method thereof. Generally vae copolymer emulsions can be used without additives or modifiers and ideally combine low environmental impact with effective performance in paints.

Acetate and vinyl chloride and acrylic ethylenevinyl acetate copolymer resins. Low odor coating composition for the paper was based on a vinyl acetate ethylene copolymer emulsion.
