All about Rubber Gasket Materials

A rubber gasket is a mechanical seal that between separate substrate sections prevents any type of leakages. They are prepared of metal because to withstand extreme pressures and wear they have to be durable enough. However different gaskets such as O-rings can be made out of synthetic rubbers or silicone. To handle the kinds of pressure and conditions associated with gasket applications these thick rubbers are enough.

In manufacturing rubber gaskets different types of rubbers are used basically because of a multitude of different environments faced by different applications. Few rubbers need to withstand both extreme cold as well as extreme heat, while others must withstand chemicals that may act as corrosives and can even result in deterioration to many types of rubber.

Below is provided information about more common types of rubber that are used in rubber gasket production.

Polyurethane is another rubber with a low-temperature limit, although compared to neoprene it has worse upper echelon heat resistance capability. In some of the coldest environments, it is used because of no matter whether it is chilled or frozen it won’t grow brittle and tear or crack.

With hydraulic fluids, Ethylene Propylene (EPR) works well due to its high resistance to corrosive fluids. To applications that experience some amount of contact with other types of liquids, it is generally well-suited.

Fluorocarbon that is often sold under the trade name Viton Rubber Cord is another all-purpose rubber that compared to nitrile rubber has a higher temperature range. In many diverse applications such as oils, fluids, and gases, as well as certain types of acids it can be used.

Nitrile rubber, or Buna-N, is a rubber that is used for general purposes and has a good temperature range (-65 to 300 degrees F). It gives good wear resistance and will not easily crack.

Neoprene generally has a low-temperature range and it can be used in applications where temperatures dip as low as -65 degrees F. For this particular reason, it’s frequently used with refrigerants in refrigeration and air conditioner units.

Along with maintaining dielectric strength and chemical inertness, PTFE can withstand very high heat (up to 500 degrees F). It is used in many applications by Rubber Gasket Manufacturer where water can be an issue as it resists all water.
