(5) Tasteless, non-toxic, environmentally friendly Production Process
Polyvinyl alcohol is polyvinyl alcohol with different degrees of alcoholysis that is saponified under the action of different amounts of alkali to produce polyvinyl acetate through polymerization reaction of vinyl acetate. The cold-soluble polyvinyl alcohol powder is made from part of the alcoholysis polyvinyl alcohol through cryogenic milling. It is a water-soluble environmentally friendly white solid powder
