Polyvinyl Alcohol : PVA-Polyvinyl-Alcohol-pva 0388

                              PVA Polyvinyl Alcohol pva 0388



0388
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 waterits transparent is
 aqueous solutionnon toxic and harmless, security and environmental.
   Chemical resistance: At normal temperature, its PH value is about 5-7, viscosity is 
steadyhardly 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 chemicalin powder building materialscaking 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 transportation
Packing: 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.
Transportation: when transport KP line products shuld use clear conveyance and avoidmoisture,
rain,sun and carry gentlyto prevent smash package.
