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.
