Frequently Asked Questions
PVA 17-99 is more resistant to solvents like benzene and chlorinated hydrocarbons compared to 17-88. It also has a higher dissolution temperature (90-95℃) and is more sensitive to gelation when borax is added.
It improves the cement setting speed and early strength, provides excellent film formation, and enhances durability, preventing powdering even when applied in thin batches.
Yes, it is often used in combination with cellulose ether water-retaining agents to improve the flexibility, water retention, and bonding strength of cement mortars and gypsum materials.
PVA should be stored in a cool, dry warehouse. It is essential to keep the product moisture-proof and fireproof to maintain its chemical stability.
The discoloration of polyvinyl alcohol during heating can be effectively inhibited by adding 0.5% to 3% boric acid to the formulation.
Yes, our high purity PVA is non-toxic and non-irritating to human skin, making it suitable for various daily chemical and additive applications.
