Polyurethane roller

English introduction:The characteristics of polyurethane roller are:

1. The resistance strength range of polyurethane idler. It still has the elongation and resilience of vulcanized rubber at high hardness. The resistance strength range of polyurethane elastomers is Shore A10-D80.

2. The compressive strength of polyurethane idler is high. Under the counterstrength of vulcanized rubber, their tensile compressive strength, tear compressive strength and fatigue strength are much higher than those of universal vulcanized rubber. Under high hardness, its oscillating compressive strength and bending compressive strength are much higher than those of plastic.

3. The polyurethane idler has excellent wear resistance and corrosion resistance, generally within the range of 0.02-0.10(cm3)/1.61km, which is about 3-5 times that of vulcanized rubber.
4, polyurethane roller oil resistance. Polyurethane elastomer is a strong optical polymer compound, and the affinity of non-optical mineral oil is small, and it is basically not corroded in light fuel oil and mechanical lubricating oil. 5. Polyurethane idler has good oxygen and ozone resistance.
6. Polyurethane idler has good vibration absorption performance and can be used for shock absorption and buffering. In the die-casting mold processing industry, replace vulcanized rubber and compression spring.
7. It has good ultra-low temperature performance.
8, polyurethane roller light radiation resistance. Polyurethane materials have good resistance to shock radiation, and still have assured process performance under 10-10 Ge radiation dose.
9, polyurethane roller has good machine commandment process performance (turning, milling, grinding, drilling can be).
In addition, the structure of polyurethane idler is polyurethane elastomer, which not only has the high toughness of plastic, but also has the high elasticity of vulcanized rubber, and has the function of shock absorption and relief. In the die-casting mold processing industry, it is usually used to replace vulcanized rubber and compression spring.
