Polyurethane is TPU is Thermo Plastic Urethane short, the Chinese full name: thermoplastic polyurethane elastomer, TPU is a diphenyl methane diisocyanate, toluene diisocyanate and macromolecule polyol, chain extender polymerization reaction of polymer materials The Its molecular structure is composed of diphenylmethane diisocyanate, toluene diisocyanate and chain extender obtained by the rigid block and diphenylmethane diisocyanate, toluene diisocyanate and macromolecule polyol reaction of the flexible segment composed of alternating.

Cast iron bag polyurethaneCastersHas the following advantages:

1. With excellent high tension, high tension, toughness and anti-aging, is a mature environmentally friendly materials.

2. With other plastic materials can not match the high strength, good toughness, wear, oil, water, anti-aging,

At the same time it has a high waterproof moisture permeability, antibacterial, mildew, anti-ultraviolet and energy release and many other excellent features.
