Polyurethane Material Properties
Selection of polyurethane materials for overflow parts
1. Tongge has been developing polyurethane materials for more than 30 years, which is unique in elasticity and high wear-resistance, and the selection of corresponding grades of polyurethane materials can meet the requirements of use in different environments, which is suitable for cyclone linings, ball mill linings, flotation machine stator and rotor covers, elastic sieve boards, concrete pump pistons, slurry pump sheaths and impellers covered with rubber, pipeline linings and so on, which has excellent wear-resistance and durability properties.
2. Selection of several kinds of overcurrent parts of the product cladding materials
A2090 Good abrasion resistance, good pressure bearing, price advantage.
A2370 high wear resistance, wear resistance is about 1.5-2 times of A2090.
