Compared with general rubber rollers, what are the characteristics of polyurethane coated rollers?
Polyurethane coated rollers are manufactured from liquid polyurethane materials according to the casting method. Compared with general rubber rollers:
Polyurethane coated rollers have higher impact toughness, which is 2-3 times that of natural rubber, and have extraordinary wear resistance, which is 3-5 times that of natural rubber; outstanding resistance to expansion; wide coverage of strength ( And it still has high elasticity under high toughness, which is not available in other rubber types); the surface smoothness is high; the performance of mechanical processing and manufacturing: the adhesion to metal materials is also much higher than that of general vulcanized rubber, which is more suitable for certain lines Speed ​​and high pressure application.
The specific service life of polyurethane coated rollers is generally 3 times that of general rubber rollers. Reliability and adhesion are excellent, and it is used under high load conditions. Very high wear resistance, polyurethane material has very good compressive strength, resilience compressive strength, impact resistance, wear resistance, aging resistance, hydrolysis resistance, wear resistance and other advantages. Polyurethane material transport rollers are used for express sorting, packaging, transportation and automation technology industrial equipment, and metal material rollers are used to transport raw materials.
