Polyvinyl alcohol powder is made of polyvinyl alcohol produced by petroleum ethylene method as raw material, and its water solubility is better than that produced by calcium carbide acetylene method.
Product Name: Polyvinyl Alcohol
CAS number: 9002-89-5
Other name: PVA2488 / 088-50
Polyvinyl alcohol powder is not suitable for building mortar additives. It can improve the flexibility, water retention and viscosity of the mortar.
In addition, it can reduce the friction of the mortar, thereby enhancing the work efficiency and quality, preventing the cracking and falling off of the plaster layer, and increasing the adhesion strength and smoothness.
