PVA 088-35 & PVA 2088 is a fully hydrolyzed high-grade
polyvinyl alcohol with non-toxic and non-polluting properties, usually appearing as white or
slightly yellow granules or powder. It is soluble in water but insoluble in organic solvents
and organic acids. It has excellent film-forming properties, oil resistance, chemical
resistance, and good stability and is mainly used in the textile, construction, chemical,
and agricultural industries.
Polyvinyl alcohol PVA is a kind of water-soluble resin produced by
polymerization and alcoholysis of vinyl acetate. Due to its
unique features of high
cohesiveness, membrane tenacity, smoothness, solvent resistance, gas inhibitor, wear
resistance, protective colloid, and waterproof after specially treated, polyvinyl alcohol is
widely applied in textile, building, papermaking, packing, timber processing, agriculture,
printing, polymer chemical, ceramic, iron and steel, electronic, electrolytic,
electroplating and other industries.
PVA 2088 is mainly used in reducing removal in the process of sizing and weaving to maintain factory cleaning; as fiber reinforcement in concrete; as an agent in medical procedures; used in eye drops and hard solution as a lubricant; mainly used as adhesive, in printing industry and textile industry. PVA 2099 can be used for heat-hardening resin denaturants, and mainly used for plywood, wood adhesives, such as urea and formaldehyde resins, melamine-formaldehyde resin, etc; also can be used as emulsion stabilizer and PVA film; widely used in construction industry, coating industry and textile industry, etc.
