Polyvinyl Alcohol
CAS#9002-89-5
Product performance
PVA is a kind of heavy polymer. it is White or light yellow
granular or powdery in appearance. its molecular formula is [CH2CHOH] n,and
the molecular formula for some of the PVA is - [CH2CHOH] n- [CH2CHOOCCH3]m-.
PVA is non-toxic, insipid and harmless. PVA is water-soluble and the solvent
provide good viscosity and film building. It can withstand oils,lubricants,
hydrocarbons and most other organic solvents. PVA has better chemical stability
and insulatibility, and provide ease in firm building; It possess the typical
chemical properties of polyots and can carry out process of esterification,
etherealization, aceatalization etc.
Product Application
PVA is mainly used in the production of warp sizing agent,
fabric finishing agent and raw material of vinylon fiber in the textile
industry,well cementation in
the field of Oil and gas exploration, 3D printing material, 107 glue, interior
and exterior wall coating and bond in the architectural decoration industry;
polymeric emulsifier,dispersant, PVF, PVL and PVB in the chemical industry;
paper bond in the papermaking industry; soil modifier, pesticide synergist and
degradable PVA film in the agricultural industry; as well as cosmetics and
high-frequency quenching agent, etc.
