Hi friends,we PVA-Polyvinyl-Alcohol-Farinose are looking for dealers and buyers all over the world. Web: http://en.shkaidu.com/ Contact me:Victor Huang,Email: email@example.com,Skype:victorhuang586,Phone:+86 13524557984.
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.
PVA Powder is the selection of high quality of PVA, and environment-friendly water soluble polymer.Ittakes 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 Polymer emulsion
Chemical resistance:At normal temperature,its PH value is about 5-7, viscosity issteady, 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
PVA1799S can used to produce film and asbestos.
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 120mesh, because below 120 mesh it is difficult to dissolve and make the surface unsmooth.
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 clearconveyance and avoidmoisture, rain,sun and carry gentlyto prevent smash package.
