Introduction:

Polyurethane, commonly a new composite material between plastic and rubber, is formed after chemical reaction of
polymer polyalcohol and isocyanate through chain extension and cross linkage. It is divided into polyether and
polyester according to its backbone chain.

Characteristic:

1.Resilience (high or low) 
2.Excellent abrasion resistance 
3.Light weight relative to metals / Lighter than metals 
4.Impact and shock resistance 
5.Bonding to metals and plastics 
6.Compression modulus (high to low) 
7.Cut and tear resistance 
8.Flex fatigue resistance 
9.Friction (high or low) 
*0.Good electrical properties 
*1.Oil, solvent, water, ozone resistance 
*2.Age resistance 
*3.Mold, mildew, fungus resistance 
*4.Non-marking characteristic 
*5.High load capacity 
*6.Chemical resistance 
*7.Machinability 

Application:

PU is used for shock absorption backing plate, spacer and springof metallurgy, coal mine, petroleum, automobile, 
building material, sports, heavy machine and large press equipment as well as die of metal plate and tube.
