Main Uses

  This product is a very versatile intermediate. It can be used to prepare various coupling agents and special silicone oil.

  In rubber industry, the strength of polyurethane elastomer can be improved by introducing polar group (chloropropyl); vulcanized rubber with low permeability, rolling resistance, high elasticity and elongation can also be synthesized; and it can be used as ballistic solid tire in military.

  In the plastics industry, it can effectively inhibit the percolation of polyvinyl chloride (PVC) plasticizer, keep PVC clean and sanitary for a long time, and can be used as absorbent of polyurethane foam plastics to improve the weatherability of foam plastics.

  In the textile industry, fabric treatment agent can be made to make the fabric soft and elastic, and to prevent the fabric from yellowing, improve the dyeing performance of the fabric.

  In the printing industry, negative toner can be made for electrostatic copying, image development and so on.
