VAE Emulsion(EVA Emulsion)
VAE Emulsion is an abbreviation for vinyl acetate–ethylene copolymer emulsion, which is a macromolecular emulsion, copolymerized by the high pressure emulsion polymerization method, after addition of emulsifier and initiator, with the vinyl acetate and vinyl monomer as the basic raw materials. VAE Emulsion is milk white or slight yellow in appearance.
Vinyl acetate–ethylene copolymer is an important product in the vinyl copolymer, generally in an emulsion state with its vinyl acetate content within a range of 70%~95%, and called as VAE Emulsion.
Property of VAE Emulsion(EVA Emulsion)
Permanent flexibility. VAE Emulsion can be regarded as an internal plasticization product of polyvinyl acetate emulsion, because it introduces the ethylene molecular chain into the polyvinyl acetate, so the acetyl does not produce continuity, the rational degree of freedom of the macromolecular chain is increased, the steric hindrance is small, the macromolecular main chain becomes soft, and the plasticizer will not migrate, ensuring permanent product softness.
