Polyvinyl Alcohol has excellent film forming, emulsifying and adhesive properties. It is also resistant to oil, grease and solvent. It is odorless and nontoxic. It has high tensile strength and flexibility, as well as high oxygen and aroma barrier properties. However these properties are dependent on humidity, in other words, with higher humidity more water is absorbed. The water, which acts as a plasticiser, will then reduce its tensile strength, but increase its elongation and tear strength. PVA is fully degradable and dissolves quickly.
 PVA is widely used in freshwater sport fishing. Small bags made from PVA are filled with dry or oil based bait and attached to the hook, or the baited hook is placed inside the bag and cast into the water. When the bag lands on the lake or river bottom it breaks down, leaving the hook bait surrounded by ground bait, pellets etc. This method helps attract fish to the hook bait.

1. PVA 2699 Specification:

Polyvinyl Alcohol PVA2699

2. PVA 2699 Application:
PVA2699 can be used as emulsion stabilizer because PVA 2699 has a very low surface tension that can stabilize PVAC colloid particles forming aqueous emulsion but not condensation deterioration; also can be used as adhesive, in coating construction and textile industry.
