Polyvinyl Alcohol(PVA)/PVOH/Poval for Emulsion Stabilizer

 

PVA Introduction:

Polyvinyl Alcohol (PVA/PVOH/Poval) is one of the few artificially made polymers with water solubility.Its main property indicators are degree of polymerization.Degree of hydrolysis and other special indices.The typical production process of PVA is the first to covert vinyl acetate into polyvinyl acetate by polymerization in solution.Then turn polyvinyl acetate into polyvinyl alcohol by hydrolysis with relevant chemical reactions .

Deforming methods:

A:Before dissolving,Please immerse PVA into the cool water to make it swollen,And expel the air and volatiles in PVA as much as possible.Then elevate the temperature gradually,Which can efficiently prevent formation of any foam.

 

B:If foams are produced.It is recommended to stop steam heating and agitating.After the foams disappear automatically.Please Elevate the temperature gradually with agitation again.Repeatedly doing  so two or three times.The foams will be reduced significantly

 

Product Application:

Polyvinyl Alcohol can be widely used as protective colloid or Thickener for the emulsion pollymerization of Vinyl Acetate(VAc) or VAc/Acrylate.
