Polyurethane (PU)

Polyurethane (PU) is an elastomer that have good combination of wear resistance, high flexibility and tear resistant. Its hardness can be compounded or formulate in accordance to the application’s requirement, these hardness flexibility is significantly important for the rollers and bumpers applications. There are two major group of base material for polyurethane : Polyrethane ether based - It is resistant to humidity, Fungus and Hydrolytic stable and have better low temperature flexibility. Polyrethane ester-based - It is resistant to oil, fuel, and petroleum-based chemicals. it is relatively strong and inexpensive, but it can break down with continued exposure to moisture
