Polyvinyl alcohol (PVA) is a non-toxic and degradable water-soluble polymer with a white powder appearance. It is widely used in the industrial field. The core is to use its excellent film formation, adhesion, water solubility and chemical resistance
Mainly used as warp sizing agent . PVA can significantly improve the strength and wear resistance of yarns , reduce yarn breakage during weaving, improve fabric feel and wrinkle resistance, and is an important basic material in the textile industry.
Used as surface sizing agent and coating agent . Can improve the surface strength, gloss, smoothness and ink acceptance of paper, improve the printing performance of paper.
Always excellent bonding properties, as a core raw material or protective colloid , providing excellent bonding strength and stability .
As a additive in cement and mortar, it can enhance the flexibility, adhesion and water resistance of materials , effectively reduce dry shrinkage cracks, and improve the durability of building structures .
Utilizing its water solubility and biodegradability, is used to make laundry beads, pesticide packaging, etc., which can reduce plastic pollution.
Polyvinyl alcohol is a raw material for the production of high-performance fibers , used in the manufacture of automotive/building safety glass interlayer , and is a key material for strategic industries such as new energy vehicles and photovoltaics.
