Melting point of ethyl vinyl acetate.

1 201 767 0414 fax. The va comonomer interferes with chain packing reducing crystallinity and thus lowering t m and improving transparency when compared with ldpe. At 20 c a saturated solution of vinyl acetate in water contains 2 0 2 4 wt vinyl acetate whereas a saturated solution of water in vinyl acetate contains 0 9 1 0 wt water. Product description 340502.

Ethylene vinyl acetate is a type of plastic a polymer with a wide variety of uses both residential and industrial. Following ingestion or inhalation vinyl acetate is rapidly metabolized by carboxylesterases to form acetaldehyde and acetic acid. At low to moderate doses it produces irritation at the point of contact. Ethylene vinyl acetate eva is a random copolymer of ethylene and varying amounts of vinyl acetate va.

Chemsrc provides vinyl acetate cas 108 05 4 msds density melting point boiling point structure formula molecular weight etc. The food and drug administration fda has stated that ethylene vinyl acetate is safe when used in food production packaging or transportation and it s not an especially dangerous material. Robles in encyclopedia of toxicology third edition 2014. As the va content increases crystallinity decreases until at 50 the eva is.

Vinyl acetate is the acetate ester of vinyl alcohol. There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used. Chemsrc provides ethyl acetate cas 141 78 6 msds density melting point boiling point structure formula molecular weight etc. Poly ethylene co vinyl acetate vinyl acetate 40 wt.

The major industrial route involves the reaction of ethylene and acetic acid with oxygen in the presence of a palladium catalyst. At 50 c the solubility of vinyl acetate in water is 0 1 wt more than at 20 c but the solubility of water in vinyl acetate doubles to about 2 wt. Vinyl acetate is moderately toxic when administered through ingestion inhalation and peritoneal injection. Articles of ethyl acetate are included as well.

Emblem in packaging technology 2012. Since vinyl alcohol is highly unstable with respect to acetaldehyde the preparation of vinyl acetate is more complex than the synthesis of other acetate esters. Melt index 57 g 10 min 190 c 2 16kg contains 200 800 ppm bht as inhibitor 437247. 1 201 767 0743.
