PU(Polyurethane)is an engineering plastic of tough, crack-resistant and abrasion-resistant which lasts significantly longer than conventional rubbers and plastics.
Other properties:
Oil & Solvent resistance
Resistance to acids/bases
Excellent mechanical properties
Resistance to heat aging
Vibration Dampening build up (hysteresis)
