Ethylene Vinyl Acetate Copolymer Emulsion

Ethylene vinyl acetate emulsion.

Ethylene vinyl acetate copolymer emulsion.

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. The synthesis method comprises the processes of pre emulsification emulsion polymerization reaction finishing and defoaming. 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. Acetate and vinyl chloride and acrylic ethylenevinyl acetate copolymer resins.

It has better physical properties low gelation temperature and processability. 0 5 to 7 parts by weight of an acid monomer iii selected from the. It has been developed as a powerful base adhesive offering the following unique characteristics. Strong initial adhesion high wet tack good creep resistance water alkali resistance improved thickening response and safe operation.

Toughness vinyl acetate and flexibility ethylene. Vae copolymers form the basis for engineering different properties in the individual end application. Vinyl acetate ethylene vae emulsion celanese emulsion polymers is a global leader in vinyl acetate ethylene vae emulsions. It s mainly applied in automobile decoration paint ink and other fields.

An emulsion of a quarterly vinyl acetate ethylene copolymer emulsified in an aqueous medium is provided. Vinyl chloride copolymer resin is made from vinyl chloride and vinyl acetate which can be used alone or mixed. Generally vae copolymer emulsions can be used without additives or modifiers and ideally combine low environmental impact with effective performance in paints. In the general formulation it can be combined with plasticizers solvents thickening agents extenders etc.

Sumielite series is a product line of water based emulsions composed of ethylene vinyl chloride copolymer. We manufacture these high performance emulsions in all three major regions of the world at our facilities throughout north america europe and asia. Polymerization leads to vae copolymers. Vinyl acetate ethylene vae is a combination of ethylene and vinyl acetate two monomers possessing special properties as e g.

There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used. The invention relates to vinyl acetate ethylene copolymer emulsion vae emulsion and a synthesis method thereof. The quarterly copolymer comprises. The invention is characterized in that complex emulsifying agents added into a reaction system include a non ion emulsifying agent an anion emulsifying.
