Angkor Wei's new material. -- 26-99(L)

Brand：Angkor Wei's new material.
Model：PVA 2699
Appearance：White or pyrophoric solids

Product description：
Polyvinyl chloride（PVA）It's a polymeric reaction from ethylene acetate.、It's made of ethanol.，It's kind of white.、Stable、Non-toxic water soluble high molecular polymers, It melts quickly into the water.，To form a stable glue.，Water is a good solvent.。  
Polyvinyl chloride resin（PVA）The water solution is very membrane.、Emulsion。The formation of the membrane has an excellent resonance.，Solvent tolerance，Inflammability.，Strength and oxygen inhibition.。Polyvinyl chloride resin（PVA）There's both pro-water and hydro-drought bases.，So it's an interface-active substance.，So it's a high-molecular emulsion.、Protected glue during suspended polymer reaction。

Product characteristics：
Solubility：Polyvinyl chloride powder dissolves in water.。The resolution of the ol is less than95%Polyvinyl chloride resin.（PVA）It dissolves in warm water.，The resolution of the ol is greater than99.5%Polyvinyl chloride resin.（PVA）It's the only thing that dissolves.95℃Over the hot water.。
Heat stability：Polyvinylene is softened when heated.，Yes.40℃There's no significant change here.，160℃Above，Heated for a long time, it's going to turn colory.，220℃And then there's a breakdown.，Generate water、Acetic acid、Acetyldehyde and butanedehyde。
Persistence Chemical：PVAAlmost no weak acid.、Effects of weak alkaline or organic solvents，It's very oil-resistant.。
Storage stability：PVAA polymer of low viscosity，The water solution is stable at constant temperatures..The water solution does not degrade during the storage process.。
membrane：BecausePVAIt's highly sticky between molecules.，PVADiaphragm.，The membrane formed in a colorless and transparent way.，It's a good mechanical strength.，It's clean, not sticky.，Solubility is good.。Molecular membrane permeability is good.、Wet rate is high.、No electricity.，No dust.，Good printing.。
PVAIt can be seen as a linear high-molecule polymer with neurogenic hydroxyl radicals.。The hydroxyl radicals in molecules are highly active.，It's a typical chemical reaction to low ethanol.，e.g. esterification，Etherification，Ellipse, etc.，It can also react to many inorganic or organic compounds.。
