It is used to produce Polyurethane sieves, PU rollers and other elastomer. It should be processed by mid-temperature casting machine.
The final product enjoys good anti resistance ability, good rebound. And the hardness can be adjusted by the different ratio. The color can be adjusted by pigment. Application: automotive kits, pipe cleaners, etc., polyurethane large or small product components. SPECIFICATION|
