Ethylene Vinyl Acetate Copolymer Emulsion

There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used.

Ethylene vinyl acetate copolymer emulsion.

The synthesis method comprises the processes of pre emulsification emulsion polymerization reaction finishing and defoaming. It s mainly applied in automobile decoration paint ink and other fields. 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. The quarterly copolymer comprises.

Vae copolymers form the basis for engineering different properties in the individual end application. Vinyl acetate ethylene copolymer emulsion vae emulsion is a copolymer of vinyl acetate and ethylene. Ethylene vinyl acetate emulsion. Acetate and vinyl chloride and acrylic ethylenevinyl acetate copolymer resins.

Vinyl acetate ethylene vae emulsion celanese emulsion polymers is a global leader in vinyl acetate ethylene vae emulsions. 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. In the general formulation it can be combined with plasticizers solvents thickening agents extenders etc. The invention is characterized in that complex emulsifying agents added into a reaction system include a non ion emulsifying agent an anion emulsifying.

Polymerization leads to vae copolymers. Strong initial adhesion high wet tack good creep resistance water alkali resistance improved thickening response and safe operation. Sumielite series is a product line of water based emulsions composed of ethylene vinyl chloride copolymer. 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.

Vinyl acetate ethylene vae is a combination of ethylene and vinyl acetate two monomers possessing special properties as e g. We manufacture these high performance emulsions in all three major regions of the world at our facilities throughout north america europe and asia. It has better physical properties low gelation temperature and processability. It has been developed as a powerful base adhesive offering the following unique characteristics.

100 parts by weight of a vinyl acetate ethylene copolymer prepared from 95 to 60 parts by weight of vinyl acetate monomer i and 5 to 40 parts by weight of ethylene monomer ii. 0 5 to 7 parts by weight of an acid monomer iii selected from the. Generally vae copolymer emulsions can be used without additives or modifiers and ideally combine low environmental impact with effective performance in paints. Toughness vinyl acetate and flexibility ethylene.
