Hot-melt polyvinyl alcohol resin powder YF-117 (1799)

●Introduction to Yingjia Polyvinyl Alcohol PVA1799 Powder

Polyvinyl alcohol PVA1799 powder is processed by selecting high-quality Sinopec Shanghai Petrochemical Polyvinyl Alcohol 100-27 (1799), using liquid nitrogen as the medium, and undergoing 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 exhibits 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, making it suitable as a protective colloid in high-molecular emulsification and suspension polymerization reactions.
