Стержни из силиконовой резины 80 А стержень

Product Introductions:

Polyurethane (PU) is a large class of polymers containing more urethane group features

in the main chain of the molecule. It is a polymer material between plastic and rubber.

It has a high elongation. Wide range of hardness, large formula adjustment range, excellent

wear resistance and mechanical properties.

Excellent heat-insulation and sound absorption characteristics.There are different thickness

and size. Their mainly function is to reduce pressure, pu Bar is widely used as custhion,

anti=pressing and heavy load parts.

PU products with excellent oil resistance, wear consumption, low temperature flexibility

anti-aging properties.

Product Advantage:

1. A wide range of hardness. It also has rubber elongation and elastic under the high

hardness. PU elastomer hardness in the range of share A10-D80.

2. High intensity. Their break strength, tear stength and carring capacity are much higher

than the generic rubber under the hardness of rubber. It's impact strengh and bending

strengh much higher than plastic's under high hardness.

3. Wear-resistance. It has outstanding wear-resistance and 3-5 times as much as rubber

in the general range of 0.01-0.10cm3/1.61km.

4. Oil-resistance. PU elastomer is a strong polar polymer, the non-polar mineral oil affinity

small, fuel oil and machinery almost from the erosion.

5. Outstanding performance in Oxygen endurable and ozone-resistant .

6. Good absorber performance, It can do vibration and the role of a buffer. It also can

substitute rubber and spring in the modle manufacturing.

7. It has nice low-temperature porformance.

8. Radiation-resistance. PU have good resistant high-energy rays performance and still

has a satisfactory performance in the 10-10 radiation.

9. Good machining properties(cars,milling,grind and bore can)
