Polyvinyl Alcohol:PVA-Polyvinyl-Alcohol-pva-2099
PVA Powder is the selection of high quality of PVA, and environment-friendly water soluble polymer. It takes liquid nitrogen as a medium, Crushing processing in low temperature
environments, have a good at film forming property, emulsibility, cohesive property .the film it product
has great force , solvent resistance,abrasion resistance,tensile strength and oxygen denial property.
Due to PVA have hydrophilic group and hydrophobic group,so PVA couble be protective colloid as

physical and chemical properties
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,
Main Applications:
1、 PVA2099 is mainly used for the feedstock of vinylon post processing.
2、PVA2099 can still used in the field of inorganic binder、PVB resin and
temporary protection film.
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
avoid moisture,rain,sun and carry gentlyto prevent smash package.
Key words : PVA 2099,PVA
