PVA Info

CAS No: 9002-89-5

Polyvinyl alcohol has excellent film forming, , and properties. It is also resistant to oil, grease and . It is odorless and nontoxic. It has high tensile strength and flexibility, as well as high oxygen and aroma barrier properties. However these properties are dependent on , in other words, with higher humidity more water is absorbed. The water, which acts as a plasticiser, will then reduce its tensile strength, but increase its elongation and tear strength. PVA is fully degradable and is a quick dissolver. PVA has a melting point of 230C and 180190C for the fully hydrolysed and partially hydrolysed grades. It decomposes rapidly above 200C as it can undergo at high temperatures.

 

PVA is an material but exhibits as the groups are small enough to fit into the lattice without disrupting it.
 
PVA describe

PVA Powder is the selection of high quality of PVA, and environment-friendly water soluble polymer.Ittakes liquid nitrogen as a medium, Crushing processing in low temperature environments, have a good at film forming property, emulsibility, cohesive property .the film it product has great force ,solvent resistance,abrasion resistance,tensile strength and oxygen denial property.Due to PVA have hydrophilic group and hydrophobic group,so PVA couble be protective colloid as Polymer emulsion.
