Composition: 

Copolymer of hydroxy alcohol, ethylene oxide and propylene oxide 

Properties: 

This series of products have the properties of both end-capped polyether and alcohol and it has hydrophilic group and self-plasticizing properties itself. The final products has better polarity, ductility, tensile strength.It is mainly used as chain extender in C.A.S.E., PUD, chain extender for epoxy resin industries. In glass fiber composite and carbon fiber industries, the performance of PUD sizing agent is better than foreign counterparts.
