Polyethylene vinyle acetate structure. 224 weather resistance adhesiveness and weldability rise with comonomer content while the chemical resistance decreases. 47 but elevated temperature and presence of some additives for example high amounts of clay cause the production of pungent acetic acid odor which is a product of thermal degradation. There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used. 8 10 ethylene vinyl acetate eva.

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. Poly vinyl chloride co vinyl acetate co vinyl alcohol 1 product result match criteria.

Poly ethylene vinyl acetate 1 product result match criteria. Ethylene vinyl acetate copolymer does not have an acid odor if it is not thermally degraded. George wypych in handbook of odors in plastic materials second edition 2017. Poly vinyl alcohol pvoh pva or pval is a water soluble synthetic polymer it has the idealized formula ch 2 ch oh n it is used in papermaking textile warp sizing as a thickener and emulsion stabilizer in pvac adhesive formulations and a variety of coatings.

It is the most widely used plastic in the world being made into products ranging from clear food wrap and shopping bags to detergent bottles and fuel tanks. Polyethylene light versatile synthetic resin made from the polymerization of ethylene. Vinyl acetate 12 wt. Poly ethylene vinyl acetate 1 product result match criteria.

Poly ethylene co vinyl acetate vinyl acetate 12 wt. Polyethylene is a member of the important family of polyolefin resins. It is commonly supplied as beads or as solutions in water. 235 due to decreasing crystallinity ethylene vinyl acetate copolymers are getting softer with increasing comonomer content.

It is colourless white and odorless.
