SINOPEC CHUANWEI SUNDY Polyvinyl Alcohol PVAL NJ-II 2488
PVA is a fine-grained polymer, which is easy to disperse in cold water, and can quickly disperse in water. Its aqueous solution has good viscosity stability, which can improve many characteristics of cement mortar, and also has the function of adsorption.
Discription:
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.
