■Overview of Products
Polyurethane (PU) is mainly characterized by oil resistance, wear resistance, low temperature resistance, aging resistance, high hardness, excellent elasticity and good anti-toxicity. It is often used in high-hardness particles and medium pipelines containing gas and liquid. Its sealing performance is good and its wear resistance is high. Polyurethane has a good name of "wear-resistant rubber", and its oil resistance is no less than that of nitrile-butadiene rubber, which is equivalent to polysulfide rubber. It is very suitable for all kinds of medium pipelines which require high sealing and high strength particle erosion.
