We can suppy PVA 17-99, 17-88, 18-99, 20-99 and other PVA series. Application: PVA 17-99F(L) is mainly used as production materials of vinylon, and it can also be employed to make Polyvinyl Butyral, textile sizing materials, coatings and adhesive, etc. PVA 17-99(L) is chiefly used to produce textile sizing materials, coatings, adhesive and it is widely used for paper processing, emulsifying agents, dispersants and blocking colloids. Besides, it can be employed as membranes, soil modifiers, etc. PVA 17-99(H) is mainly used to produce textile sizing materials, coatings, adhesive, acetal derivations, and it is extensively applied to paper processings, emulgents, dispersants and blocking colloids. In addition, it can be used as membranes, soil modifiers and production materials of vinylon fiber. PVA 19-99(L) and 18-99(H) are particularly applied to making coatings and adhesive. PVA 17-88 is chiefly used for coatings, adhesive, dispersing agents, emulgents, textile sizing materials, sensitize coatings and so forth. Attention: The contents of NaAC in flaky PVA is lower the PVA in the form of floss, and its PH value is different due to the differences of the technological processes. Processes. Proper adjustment ought to be done according to the requirements for PH value. In the quality system. Explanation of the standard code: H: High Alkali Alcoholysis L: Low Alkali Alcoholysis F: Mainly used as a raw material of the production of Vinylon fiber Without F: Other uses except for Vinylon fiber 99: Alcoholysis 17: Polymerization Package: Packed with polypropylene woven bags. Storage: PVA must be laid in a dry and well-ventilated place, keep it away from insulation, moisture, central heating or other heaters.
