New engineering plastic --- macromolecule polyethylene cushion block

1, ultra-high molecular weight polyethylene cushion block, wear resistance in plastic first, and the larger the molecular weight, the higher the wear resistance and impact resistance of materials;

2, the impact strength of ultra-high molecular weight polyethylene cushion block is the highest value in existing plastics, even at 70 degrees centigrade, there is still a high impact strength;

3 、 self lubrication;

4, ultra-high molecular weight polyethylene cushion block, water absorption rate is very low. Therefore, the physical and mechanical properties are independent of the humidity factors used in the working conditions;

5. Ultra high molecular weight polyethylene block, chemical stability, in a certain temperature, concentration range, can be acid, alkali, salt and other corrosive media and organic solvents corrosion;

6. Ultra high molecular weight polyethylene block, tasteless, non-toxic, odorless, itself non corrosive, has physiological, cyclical and physiological adaptability

7, non adhesion;

8. When the molecular weight of HDPE exceeds 500 thousand, the brittleness temperature decreases to 140. Ultra high molecular weight polyethylene can even be under liquid nitrogen, its use temperature of less than 269 degrees centigrade, there is still a certain mechanical strength.

Application of ultra high molecular weight polyethylene:

1 lining: bin, hopper, wear-resistant plate, bracket, chute and other reflux device, sliding surface, roller, etc.;

2, food machinery: guardrail, star wheel, guiding wheel, roller, bearing liner etc.;

3, paper machinery: suction tank cover plate, deflector, wiper plate, hydrofoil;

4, chemical industry: packing plate, packing material, vacuum mold box, pump parts, bearing liner, gear, sealing interface;

5, other: agricultural machinery, ship parts, electroplating industry, extremely low temperature mechanical parts
