We often use polyurethane rollers in papermaking, printing and dyeing, printing, metallurgy and other fields. It is a new type of polymer composite material between rubber and plastic.
1. Polyurethane roller hardness range Shaw A10-D80, at high hardness still has the rubber elongation and resilience.
2. In rubber hardness, their tear strength, tear strength and load-bearing capacity is much higher than the general-purpose rubber, high hardness, the impact strength and bending strength higher than the plastic.
3. With outstanding wear resistance, the wear resistance is generally in the range of 0.01-0.10 (cm3) / 1.61km, about 3-5 times the rubber.
4. And non-polar mineral oil affinity is very small, almost no erosion of fuel oil and mechanical oil.
5 has a good high-energy radiation, radiation dose in the 10-10 Ge still have satisfactory performance.
In addition, the internal structure of polyurethane roller polyurethane elastomer, both with high strength plastic, but also has a high elasticity of rubber, with damping, cushioning function, in the mold manufacturing industry, usually used to replace rubber and spring.
