Kay letter is specialized in producing PU polyurethane caster wheel manufacturers, producing a variety of heavy-duty casters and polyurethane rubber tire business. Extensive production experience, professional production equipment, adhering to the "quality in essence, simplicity" purpose products, the products won the majority of customer recognition and praise. In addition to a variety of standard wheels company according to different requirements of customers tailor, welcome customers to sample processing.

A, PU polyurethane wheels:

Polyurethane elastomer is a new type of polymer composite materials of between rubber and plastics, both with high-strength plastic and has a high elasticity of rubber.

Two, PU polyurethane wheels Features:

1, has a good low temperature performance;

2, good resistance to oxygen and ozone;

3, has a good mechanical processing performance. (Turning, milling, grinding, drilling may be);

4, vibration absorption performance, do shock absorption, cushioning effect. In the mold manufacturing, instead of rubber and springs;

5, wear. Its wear resistance is very prominent, usually within 0.01-0.10 (cm3) /1.61km range of about 3-5 times the rubber;

6, radiation resistance. Polyurethane resistant to high-energy radiation performance is very good, at 10-10 Ge radiation dose still has satisfactory performance;

7, wide range of hardness. In the high hardness of rubber still has elongation and resiliency. Hardness range of polyurethane elastomer Shore A10-D80;

8, oil. Polyurethane elastomer is a strong polar polymers, and the affinity of small non-polar mineral oil, fuel oil and lubricating oil is almost free from erosion;

9, a high strength. Much higher in the rubber hardness of their tensile strength and load-bearing capacity than common rubber. In the high hardness and bending strength impact strength is much higher off than plastic;
