Poly Ethylene Co Vinyl Acetate Solubility

This polymer is readily available with a variety of va contents generally ranging from 0 to 40.

Poly ethylene co vinyl acetate solubility.

Ethylene vinyl acetate is a copolymer containing the semi crystalline polyethylene and amorphous vinyl acetate and these are commonly used as rate controlling membranes in drug delivery devices. Melt index 57 g 10 min 190 c 2 16kg contains 200 800 ppm bht as inhibitor cas number 24937 78 8. Furthermore it was confirmed that the additive must present a reduced solubility at a temperature close to the crude oil cloud point. Poly ethylene co vinyl acetate vinyl acetate 12 wt.

There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used. Melt index 8 g 10 min 190 c 2 16kg sorry we cannot compare more than 4 products at a time. Not only the solubility parameter and the vinyl acetate content but also the molecular weight and polydispersity have an important influence on both phase behavior and pour point depression. 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.
