Polyurethane products

Our company produces the KP-09 ultra-high-molecular-weight sheave lining block using imported materials, which boasts exceptional wear resistance (its mortar abrasion rate is just 1/10 that of PVC, 1/7 that of carbon steel, and 1/27 that of brass), excellent impact resistance (with an impact strength exceeding 180 kJ/m²), outstanding self-lubricating properties (featuring a friction coefficient of only about 0.10), and remarkably high tensile strength (over 35 MPa). Additionally, it exhibits superior corrosion and water resistance, maintaining stable performance across a wide range of organic and inorganic media. The material also demonstrates exceptional low-temperature durability and is completely hygienic and non-toxic.

We can produce products in various shapes and specifications according to customer requirements.
