PVPVA series use as stiffener, its hygroscopic decrease as the ratio of vinyl acetate increase, it suits for Mousse, hair casehardened liquid, if mix with PVP-K30 can strengthen hardened effect.
-
Other technological usage
- Use as remoisten binder, bond for paper and coating bond;
- Use as thickener for kinds of paints and protectionability colloids;
- Water-solubility PVP/VA64 series are the usual emulsifier for plant protect agent and protectionability colloid;
- The best bond of preparation effervescence troche in hydro-mixture with absolute ethyl alcoholin
pharmaceutical area. The excellence does not absorpt moisture and has good crushability.
