High quality Polyurethane printing roller manufacture


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)

Food grade applications
