Polyvinyl alcohol can be used in textile pulp, vinylon fiber, paper coating agent, building coatings, adhesives, PVA film, PVB raw materials, food and medicine and other fields, PVA can also be used as soil modifier, polymerization suspension agent and emulsifier, quenching agent and so on.
Various excellent properties make polyvinyl alcohol one of the most popular substances in the world. There are two important indicators of polymerization degree and alcoholysis degree. The textile industry uses slightly lower polymerization degree, the adhesive industry uses high polymerization degr
Polyvinyl acetal is prepared by treating polyvinyl alcohol with aldehydes. Butyraldehyde and formaldehyde provide polyvinyl butyral (PVB) and polyvinyl formal (PVF) respectively. In the United States and Western Europe, the preparation of polyvinyl butyral is the largest use of polyvinyl alcohol. Po
