Castable polyurethane elastomer (CPU) is a kind of polymer material between rubber and plastic. It has been widely used in many fields because of its excellent wear resistance, high mechanical strength, excellent oil and chemical resistance and good low temperature flexibility. Here are some of the main application areas for CPUs:
1. Defence industry: Used for airtight cushions of various cannons, bulletproof plates of armored vehicles, missile head shields, etc.
2. Light textile industry: including spinning rubber roller, printing and dyeing rubber roller, food processing rubber roller, chemical fiber pelletizing rubber roller, fiber drawing rubber roller, textile speed-up wheel, artificial leather, etc.
3. Transport and railways: Used for automotive parts such as bumpers, steering wheels and dashboards; Solid tyres, wharf fenders, cold cushions for passenger cars, oil rims for locomotive fuel tanks, baffles and shock absorbers under locomotive covers and train sleepers.
4. Mechanical Industry: As various oil-resistant, wear-resistant, shock-absorbing seals, as well as key structural materials on engineering machinery, as well as transmission belts, wear-resistant linings, groove linings and carrier rollers of steel pipe straightening machines, steel rollers, etc.
5. Sports: Used for polyurethane track, gymnastics training ground, ski boot pulley, skate pulley, etc.
6. Mining industry: Used for mine screen plate and screen mesh, lining of ore dressing equipment, lining of ball mill, friction lining of hoist, etc., to improve service life and reduce cost.
7. Self-healing material field: The latest research progress shows thatThe CPU can be used to develop elastomers with self-healing performance, and the materials can recover their original structure and function after being damaged, and are applied to the fields of automobile coating, wearable electronics, soft robot, biomedicine and the like.
These applications of the CPU demonstrate its important role and potential as a multifunctional material in modern industry.
