Polyvinyl alcohol is an organic compound with the chemical formula [C2H4O] n. It appears as a white solid in the form of flakes, flocs, or powders, and is odorless. Soluble in water (above 95 ℃), slightly soluble in dimethyl sulfoxide, insoluble in gasoline, kerosene, vegetable oil, benzene, toluene, dichloroethane, carbon tetrachloride, acetone, ethyl acetate, methanol, ethylene glycol, etc. Polyvinyl alcohol is an important chemical raw material.
Feature
1. White or slightly yellow powder or flocculent solid.
2.Soluble in hot water at 90-95 ℃, almost insoluble in cold water.
3. The discoloration of polyvinyl alcohol during heating can be inhibited by adding 0.5% to 3% boric acid.
4.Good light resistance, not affected by light.
5.It has chemical reactivity such as esterification, etherification, and acetalization of long-chain polyols.
6.Open flames can burn and have a special odor. Non toxic, non irritating to human skin.
Technical specifications vary across grades to meet diverse industrial needs. Key parameters include viscosity, molecular weight, and solubility, which influence performance in end-uses. Below is a comparison table highlighting core attributes for our BP series:
| Model | Viscosity (mPa·s) | Molecular Weight (approx.) | pH Range | Solubility |
| BP17 | 17-20 | 85,000 | 5-7 | Water-soluble |
| BP24 | 24-27 | 100,000 | 5-7 | Water-soluble |
| BP26 | 26-29 | 110,000 | 5-7 | Water-soluble |
| BP20 | 20-23 | 95,000 | 5-7 | Water-soluble |
| BP05 | 5-8 | 70,000 | 5-7 | Water-soluble |
Clients benefit from these features through improved efficiency in production lines, such as faster drying times in adhesives or enhanced flexibility in textile coatings. For instance, the BP24 grade's higher viscosity suits heavy-duty bonding, while BP05 is optimal for low-viscosity applications like paper sizing. This adaptability translates to cost savings, as users can select the exact grade to minimize waste and optimize resource use. Additionally, the water-soluble nature simplifies cleanup and reduces environmental impact, aligning with green initiatives.
