YingjiaYP Polyvinyl Alcohol Powder Introduction

 

 Contact: Mr. Shi, Shanghai Yingjia Industrial Development Co., Ltd. 17317720738

Polyvinyl alcohol powder is made from selected high-quality flake polyvinyl alcohol, using liquid nitrogen as the medium, and processed through crushing under low-temperature conditions. It is a water-soluble, environmentally friendly high-molecular polymer with excellent film-forming, emulsifying, and adhesive properties. The film it forms has outstanding adhesion, solvent resistance, friction resistance, tensile strength, and oxygen barrier properties. Because polyvinyl alcohol contains both hydrophilic and hydrophobic functional groups, it acts as an interface-active substance. Therefore, polyvinyl alcohol can serve as a protective colloid in high-molecular emulsification and suspension polymerization reactions.
