PVA17-99 Scope of Application

1.The solution prepared by the product can be used as the thickener and anti-flow agent of the emulsion.
2.For paper surface sizing can improve paper strength and ink absorption.
3.The crosslinking performance of the product can be used to prepare various water-resistant adhesives.
4.For the production of paper and building glue.
5.For the production of polyvinyl alcohol fiber, water-soluble fiber.
6.Fiber paste: the film has good forming performance, soft and strong tensile resistance and elasticity, but also has the characteristics of friction resistance, implication, smoothness and good feather effect. And compared with starch pulp, there is no need to worry about spoilage and mildew.

PVA2099-99 Scope of Application

1. Adhesives and adhesives: used for office paste, rewetting paste, paper tube, paper bag, carton, glued paperboard, glued wood board, non-woven fabric, etc. It is used for building materials, iron, acid salt, ceramics, pottery, ink, paint glue, paint glue, cement mixture for concrete strengthening, etc.
2.Fiber size: good film forming performance, soft and strong tension resistance and elasticity. It also has the characteristics of friction resistance, involvement, smoothness and good feather effect. And compared with starch size, there is no need to worry about corruption and deterioration, and mildew rarely occurs.
3.Paper industry: it can be used for surface coating and polishing, which can significantly improve the ester resistance, solvent resistance and water resistance, and produce higher fabric strength. It can also be used as adhesive in coating system and carrier of optical polishing agent.
4. Polymerization agent: used as an effective dispersant or stabilizer. They are mainly used as protective colloids and can enhance emulsification at very low concentrations.
5. Polyvinyl alcohol can play a role in many other industrial applications, such as ceramics, water-soluble films, peelable coatings and temporary adhesives for non-woven products. These products can also be used in various building materials, such as putty and plaster.
