Rubber and metal bonded products have a wide range of applications in various fields such as automobiles, rail transit, engineering machinery, household appliances, aerospace, etc., such as engine suspensions, shock absorbers, oil seals, brake pads, pipeline joints, etc.

In the market, we often observe that even for the same type of rubber products, products manufactured by different manufacturers have significant differences in texture.

NBR (nitrile butadiene rubber), with its excellent oil and heat resistance, has been widely used in the field of seals. However, its relative lack of wear resistance limits its potential application in high-wear environments.

Black and white are the basic colors in color, but they are also the two most difficult colors to achieve satisfactory results. Usually, black is achieved by adding carbon black or black mother, but it is often difficult to achieve the desired blackness or effect.

Perflurane rubber (FFKM), whose structure combines the main chain of tetrafluoroethylene (PTFE) with the branch chain and connecting parts of perfluoromethyl vinyl ether (PMVE), not only exhibits excellent resistance to high temperature and chemical corrosion (resistant to more than 1,600 chemical substances), but also retains the elastic properties of rubber.

In order to more comprehensively analyze the problem of surface roughness of EPDM extruded products, it becomes essential to combine the data analysis with the measurement parameters in actual production.
