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

Modified nitrile rubber
Nitrile rubber is the most common type of elastomer used in the sealing industry. It has high elasticity and superior mechanical strength, with 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 adhesives and pigmented binder products.
While nitrile has some advantages over other types of rubber, it is not suitable for all applications. It has limitations when it comes to certain fluids and is not compatible with phosphate-ester hydraulic fluids. It is incompatible with sunlight and has poor weather resistance. It is not suitable for high temperature applications but can be improved by compounding. Finally, Nitrile O-rings should not be stored near ozone generating equipment.
Chloroprene
Neoprene is a polymer with excellent mechanical properties. It also exhibits good flame retardancy and abrasion resistance, and has strong antioxidant and heat resistance. It is commonly used in oil and gas applications. Typical applications include belts, coated fabrics, leggings and oil rubber seals. Polyurethanes are a family of synthetic rubbers that fall into two basic groups: polyesters and polyethers. These materials have excellent mechanical, chemical and electrical properties, making them ideal for oil and gas applications.
One of the advantages of neoprene is its resistance to oils and solvents. It is an excellent choice for oil resistant neoprene packing gaskets and gaskets. Additionally, the material is easy to clean and repair, making it an excellent choice for automotive oil pan sealing. It can also be used to seal other fluid-filled components such as fuel tanks and water pipes.
Silicone Rubber
Silicone rubber oil seals are made from a variety of materials. Among them are PTFE, FKM, NBR, EPDM, PTFE and Silicon. These materials are highly resistant to oil, water and ozone. They are often used in applications that come into contact with human body fluids. Whether the material is used for mechanical seals or insulating layers, silicone is a versatile choice.
