Rubber material for heat-resistant, abrasion-resistant rubber roll MG-AWZ-992
MG-AWZ-992 is a groundbreaking new material with heat resistance and abrasion resistance that exceeds conventional materials.
It has abrasion resistance comparable to urethane rubber, and further, it is excellent rubber material for rubber rolls that can be used even where heat-resistance, oil-resistance, and chemical-resistance are required, which were obstacles for urethane rubber, Hypalon, NBR, etc.
