The interpenetrating network structure polymer plastic alloy formed by blending modified PVA and modified starch is biodegradable. Films suitable for food packaging, agricultural water-soluble films, containers and disposable consumer products are often produced.

PVA hydrogel has the characteristics of water content, elastic modulus, low friction coefficient, high mechanical strength, rich pore leakage network structure, and good biocompatibility similar to the natural tissues of the human body.

A new type of medical non-fiber sponge formed by introducing sodium polyacrylate side chains into PVA macromolecules is called ionized polyvinyl alcohol sponge. It has good biocompatibility and stable chemical properties, and has excellent hydrophilicity, liquid absorption and Blood-sucking performa......

In people's daily lives, packaging materials can be seen everywhere, and packaging materials used in food are given more missions. It needs to protect food from external pollution and isolate the air.

Domestic demand and exports of high-quality, high-density and high-end textiles have increased. The development of high-end paper industry and petroleum extraction has accelerated.

Polyvinyl alcohol is an excellent protective colloid and dispersant for vinyl acetate homopolymerization or copolymerization with other monomers to produce emulsion (white glue), which is very important in the production of white glue.
