Product name: PVA2488 the same with PVA 224

PRODUCT DESCRIPTION

PVA resin is a kind of heavy polymer. It is white or light yellow floc, Granular or powdery in
appearance. Its molecular formula is[CH2CHOHn,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 so-lvents.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.

PRODUCT APPLICATION

In textile industry, PVOH is mainly used as a warp dressing agent, textile finishing agent
and the raw material of vinylon; in construction and upholstery industry 107 glue,
it's used as an additive of cement and mortar, inner and outer wall paints, and moulding
board binder;and in chemical industry,it's used as a polymer emulsifying agent,dispersing
agent and used to produce PVOH formal,PVOH acetal and PVOH butyral. It's used as an
adhesive in lumbering and paper-making industries, used as a soil improving agent,
pesticide reinforcing agent and PVOH thin film in agriculture, and used as a well-fixing
agent in petroleum exploitation. It can also be used into cosmetic, medicine, printing,
ceramics, steel-making, electronics and plating

 Notice:

 Partially hydrolyzed grades can be easily dissolve in cold water, so it should be cared that large and hard lumps are likely to
be formed when charging PVA into the water.
1.The water temperature should be lower than 25 when charging PVA.
2.The charging speed of PVA should be as slow as possible
3. After the charging, the slurry should be continuously stirred for about 10 - 15 minutes without     raising the temperature immediately, in order to disperse the particles efficiently.
4.The water temperature should be raised to about 95, to shorten the dissolving time. The lower  degree of polymerization is, the lower water temperature is acceptable for making solution.
