FAQ

Q1: What factors affect the solubility of Polyvinyl alcohol (PVA)?

A1: The solubility of PVA mainly depends on its alcoholysis degree and polymerization degree. At the same temperature, solubility increases with the decrease of alcoholysis degree and decreases with the increase of viscosity. Fully hydrolyzed PVA (alcoholysis degree above 99%) requires a higher temperature (90-95°C) to dissolve completely.

Q2: Is Polyvinyl alcohol (PVA) environmentally friendly and non-toxic?

A2: Yes, PVA is non-toxic and has good biocompatibility, with an LD50 (mouse) of 14,700 mg/kg. It is biodegradable under certain conditions and will not cause long-term environmental pollution, making it suitable for environmentally friendly product production.

Q3: Can the packaging of Polyvinyl alcohol (PVA) be customized according to purchase needs?

A3: Yes, PVA is usually packed in multi-ply paper bags, and bulk packaging or other customized packaging options are available according to the purchase volume and transportation needs of purchasers, ensuring safe and convenient transportation.
