Polyvinyl Alcohol pva 2688
Polyvinyl Alcohol is a few kind of synthetic with water souble high- molecular polymer.The main specification includes degree of polymerization & alcoholysis degree with
other specical performance. Polyvinyl Alcohol is manufactured by polymerization of vinyl acetate in
methanol solvent, then undergoing alcoholysis via advanced belt-process of low- alkali. After grinding, drying and packing, the end PVA products are achieved.

physical and chemical properties
Water-solubility: it dissolves quickly in room temperature water, its transparent is
aqueous solution, non toxic and harmless, security and environmental.
aqueous solution, non toxic and harmless, security and environmental.
Chemical resistance: At normal temperature, its PH value is about 5-7, viscosity is steady,
hardly be impacted by weak acid, weak base and organic solvent(ester, ketone, higher alcohols,
hydrocarbon), has high oil resistance.

Compatibility: it can be miscible with starch, synthetic resin, cellulose derivatives
& surface active agent and has better stability

Main Applications:
KP series can be widely used dry powder, powder putty, dry-mixed mortar, oilfield auxiliary chemical, in powder building materials, caking agent&bond
of plastering anhydrite. Especially suitable to be used as interior & exterior wall putty
and construction mortar, the main function is bonding, improveing the flexility, water-retaining property, reducing friction, enhancing the work efficiency and quality(to prevent
the crack&fall off from the floated coat, add adhesive strength and smooth texture).

Usage method
KP series can be used in powder building materials , after stirring and mixing evenly,
it could be use. Addition of advice: 0.3-3%of the totle putty powder.

KP series use 100-120mesh when product dry glue powder, below 100 mesh it dissolves slow, difficult completely
dissolve, when over 120 mewsh, it is easy to agglomerate. Dry-mixed mortar use 80-120mesh. Powder putty use above 120 mesh, because below 120 mesh it is difficult to
dissolve and make the surface unsmooth.

Package&storage transportationPacking: Paper-plastic package with plastic film, 20kg&25kg per bag.there are COA in every product,and
clear&firm mark in every bag.including trademark,name,model, lot number,net weight,manufacturer ect...
Store: KP line products should be stock indoor where is dry& well-ventilated, room temperature is 5-30℃, Stored in batches. do not near the power, prevent humid, avoid sun exposure. strictly
prohibit storage with volatile chemicals to prevent adsorption modification.
