PVA Product Characteristics and Instruction (BP*4) 1.Product
Performance Water-based resin is a kind of high polymer. It is
white or light yellow floc, 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
polyols and can carry out process of esterification,
etherealization, aceatalization etc. 2.Product Use *****
industry:PVOH is mainly used as a warp dressing agent, textile
finishing agent and the raw material of vinylon; ***** :upholstery
industry **7 glue, it's used as an additive of cement and mortar,
inner and outer wall paints, and moulding board binder *****
industry: it's used as a polymer emulsifying agent, dispersing
agent and used to produce PVOH formal, PVOH acetal and PVOH
butyral. d.paper industry:It's used as an adhesive in lumbering and
paper-making industries. e. agriculture: used as a soil improving
agent, pesticide reinforcing agent and PVOH thin film f. used as a
well-fixing agent in petroleum exploitation. g. It can also be used
into cosmetic, medicine, printing, ceramics, steel-making,
electronics and plating. 3.Dissolving Temperature, thickness and
time PVA products dissolvent ability is determined by the degree of
alcoholysis and polymerization. When polymerization increased, the
ability to dissolve will reduced. Likewise, when the degree of
alcoholysis decreased, the dissolvent temperature will reduced and
water solubility will increase. Fully alcoholysed PVA products are
more sensitive to temperatures changes. Such products cannot
dissolve or experience partial swell in properties when temperature
falls below required degree. Blending will be difficult and foam
created should the temperature exceed the required degree for
partial alcoholysis products. Temperature must be controlled at
acceptable range for ease of dissolving. Product Name Alcoholysis
