CHUANWEI PVA 2488 For Adhesive
Discription:
Polyvinyl Alcohol (PVA) is a water-soluble Resin made of ethylene by polymerization and alcoholysis. It has unique strong adhesion, film toughness, smoothness, oil resistance, solvent resistance, gas resistance, wear resistance It can also be specially treated to make it water resistant. PVA17-88, 24-88, 80 mesh powder can be directly dissolved in cold water, 120 mesh, 160 mesh can be quickly dissolved in cold water after dry mixing with other powders to improve the properties of building materials.
Polyvinyl alcohol 2488 is a white or slightly yellow powdery water-soluble polymer. Has good film-forming properties, formingThe film has good adhesion, solvent resistance, abrasion resistance, tensile strength and oxygen barrier properties. also hydrophilic.
There are two functional groups: base and hydrophobic group, so polyvinyl alcohol has the properties of interfacial activity, and can also be used as polymer emulsification, suspension
Protective colloid for float polymerization. Low dissolution temperature, strong freezing resistance, no gel phenomenon; good solution fluidity and stable viscosity; good hygroscopicity, Strong re-viscosity; contains more hydrophobic groups, good affinity and adhesion to hydrophobic materials.
