High Strength Paper Machine Rolls Polyurethane Material With Long Lifetime

The different kinds of Polyurethane (PU) material paper making rolls

Fine gum, good rebound elasticity, good abrasion resistance, strong tear resistance, good bending strength, tensile strength and

Large elongation at break, moderate temperature resistance (-50 degrees to +85 degrees), large adjustable range of hardness (5A to 99A Shore). Oil and corrosion resistant, environmentally friendly and non-toxic.

1. Excellent abrasion resistance

2. Wide hardness range: The hardness of polyurethane products is about Shore A10-D80, while the hardness of ordinary rubber-like Shore A60-100. It is worth noting that the polyurethane elastomer can have an elongation of 400-800% within this hardness range. When the elongation of natural rubber is 550, the highest hardness is Shore A70.

3. High strength and high elongation

4. Excellent oil resistance: Polyurethane products have better oil resistance than cyanide rubber; aging resistance is better than natural rubber and other synthetic rubbers; polyether-type PUR is better than polyester-type PUR in terms of resistance to hydrolysis, acid and alkali solution corrosion .

5, with light capacity, high strength, heat insulation, sound insulation, flame retardant, cold resistance, anti-corrosion, non-absorbent, simple and fast construction, etc., has become the construction, transportation, petroleum, chemical, power, refrigeration and other industrial sectors] thermal insulation, Indispensable materials such as waterproof plugging and sealing
