What are the advantages of different types of oil rubber seals?

Modified Nitrile Rubber

Nitrile rubber is the most common elastomer type in the sealing industry. It features high elasticity and superior mechanical strength, exhibiting good deformation behavior between -30 and 100 degrees Celsius. Its lower heat resistance makes it a popular choice for oil and fuel resistant seals. Nitrile rubber is also used in adhesive and pigment binder products.

While nitrile has some advantages over other rubber types, it is not suitable for all applications. It has limitations when it comes to certain fluids and is incompatible with phosphate-ester hydraulic fluids. It is incompatible with sunlight and has poor weather resistance. It is not suitable for high-temperature applications, but this can be improved through compounding. Finally, nitrile rubber O-rings should not be stored near ozone-generating equipment.

Chloroprene

Chloroprene rubber is a polymer with excellent mechanical properties. It also exhibits good flame resistance and abrasion resistance and possesses strong antioxidant and heat resistance. It is commonly used in oil and gas applications. Typical applications include belts, coated fabrics, gaiters, and oil rubber seals. Polyurethane is a family of synthetic rubbers, divided into two basic groups: polyester and polyether. These materials have excellent mechanical, chemical, and electrical properties, making them ideal for oil and gas applications.

One of the advantages of chloroprene rubber is its resistance to oil and solvents. It is an excellent choice for oil-resistant chloroprene rubber filler gaskets and seals. In addition, the material is easy to clean and repair, making it a good choice for automotive oil pan seals. It can also be used to seal other fluid-filled components such as fuel tanks and water pipes.

Silicone Rubber

Silicone rubber seals are made from a variety of materials. Among them are PTFE, FKM, NBR, EPDM, PTFE, and silicone. These materials have high oil resistance, water resistance, and ozone resistance. They are often used in applications involving contact with bodily fluids. Whether the material is used for mechanical seals or insulation, silicone is a versatile choice.
