Product Description

Product Description:

Cold-soluble polyvinyl alcohol powder (PVA-2488), which can be quickly and fully dissolved in tap water and cold water. Organic compound, white flake, flocculent or powdery solid, odorless. PVA 2488 is a water-soluble environment-friendly high molecular polymer with good film-forming properties, emulsifying properties, bonding properties and spinning properties. It has excellent adhesion, solvent resistance, friction resistance, tensile strength and oxygen barrier properties. Because polyvinyl alcohol has both hydrophilic and hydrophobic functional groups, it has interface activity, so polyvinyl alcohol can be used as a protective colloid for polymer emulsification and suspension polymerization.
