The oil resistance of polyurethane screen is excellent

① Polyurethane screen, generally polyester type and polyether type. It can be used to make plastic, rubber, fiber, hard and soft foam plastics, adhesives and coatings.

② Polyurethane screen products are characterized by high strength, heat insulation, sound insulation, flame retardant, cold resistance, anti-corrosion, non water absorption, simple and fast construction, etc.

③ It has become an indispensable material for construction, transportation, petroleum, chemical industry, electric power, refrigeration, etc.

④ Therefore, its re application environment is more complex, which can not avoid the contact with oil, and whether the oil has an impact on the use of polyurethane screen. Polyurethane is a high polymer made of polyisocyanate and polyether polyol, and the oil has an impact on it.

⑤ Through a large number of experiments: the oil resistance of polyurethane products is better than that of nitrile butadiene rubber, the aging resistance is better than that of natural rubber and other synthetic rubber, and the polyether pur is better than the polyester pur in terms of hydrolysis resistance, acid resistance and alkali solution corrosion resistance.
