Wear-Resistant And High-Temperature Resistant Rubber Polyether/Polyester Polyurethane PU Compound
Mechanical properties: Abrasion resistance and mild stretch are much better than known natural rubber or synthetic rubber. Especially high-hardness rubber compounds can also maintain good fluidity.
In addition to elasticity and good wear resistance, they also have good comprehensive mechanical properties.
Oil resistance: Oil resistance and fuel resistance better than NBR and HNBR.
Gas permeability: Low gas permeability, comparable to IIR rubber.
Temperature resistance: long-term use at 80 degrees Celsius. Special varieties can withstand
high temperatures of 110 degrees Celsius and 150 degrees Celsius in a short time.
Polyurethane rubber can also withstand -55 degrees Celsius.
In some applications, even when the temperature is lower than its glass transition temperature, it will still not embrittle.
Depending on the filler formulation, the embrittlement temperature can reach -70 degrees Celsius.
Application: First of all, it can be applied to track and field plastic track sports venues,
including basketball, volleyball, badminton, and tennis courts. There are two types of indoor and outdoor.
This kind of plastic ground has a longer use time than wooden floors, is abrasion-resistant, oil-resistant,
weather-resistant, and has suitable elasticity, good shock absorption performance, and solid bonding through the base.
Polyurethane rubber has excellent oil resistance, so it is also used as an oil-resistant roller.
Due to its excellent performance, it can replace other alloys in the automobile industry,
and can be used in automobile bumpers, steering wheels and automobile peripheral parts.
Secondly, due to the advantages of low wear, high friction coefficient and low noise,
the conveying device made by him has a stable speed.
Therefore, the conveyor belt used in coal mines and mines can be made of polyurethane compound rubber,
and high-hardness polyurethane cast rubber can be used as gear mercury gear,
which has the characteristics of stable transfer of liquid. In addition, it is also used as lining and protective layer,
as the lining of non-metallic car snow chains and high-rise building rescue water pipes;
as high-pressure seals and high-pressure water pipes; in terms of shoemaking, it can reduce costs and is beautiful;
it can be used as thin aircraft Wall tanks, oil-resistant seals, dust-proof seals;
used as potting materials for cable streets, electronic components and printed circuits,
and can be used as an ideal shock-proof rubber.
It also has a wide range of uses in human organs and medical and sanitary appliances.
Secondly, it is also used in the field of defense industry, such as polyurethane thermal insulation materials
in aerospace systems, which have the advantages of excellent bonding performance and high strength.
