What are the different types of oil rubber seals used for? In addition to durability, these seals have excellent mechanical properties. In addition, they have excellent resistance to many common technical oils.
Nitrile
Nitrile oil rubber seals are used for a variety of purposes. They provide superior resistance to oils and acids than most elastomers. These compounds are compatible with petroleum-based oils, silicone oils, and aliphatic hydrocarbons. They are also resistant to ethylene glycol, acids, and a variety of caustic agents. Nitrile oil rubber seals are available in different formulations and are widely used in the automotive industry.
Despite the many differences between the elastomers used in nitrile oil rubber seals, they have similar applications and desirable working properties. Nitrile, also known as Buna-N, consists of acrylonitrile and butadiene. In terms of glass transition temperature, the lower the ACN content, the lower the temperature at which the material will break down, and a higher content of ACN means improved resistance to nonpolar solvents. Nitrile seals are capable of working in temperatures ranging from -67degF to 275degF in dry heat. Nitrile carboxylated nitrile has improved oil resistance and abrasion resistance.
EPDM
EPDM oil rubber is a versatile material that is great for many outdoor applications. It is also chemically resistant and meets many drinking water standards. These properties make it ideal for the food and beverage industry. EPDM is a good choice for sealing in many other applications.
EPDM oil rubber seals are highly versatile and have many applications. This versatile material is excellent for a variety of industrial uses, including oil and gas seals, window and door seals, gaskets, washers, belts, and gaskets.
Neoprene
The material neoprene has a variety of uses. Its flexible and versatile nature allows it to be die-cut into custom gaskets and seals. While it is typically supplied in sheet form, it is available in a variety of other forms as well. Neoprene, also known as chloroprene, is composed of carbon, hydrogen, and chlorine. This makes it a great all-purpose polymer and suitable for a wide range of sealing applications.
Other materials used for oil rubber sealing include chloroprene, Buna N, and nitrile butadiene. These materials are highly resistant to petroleum products, but may not be as ozone resistant as Neoprene. This material is more cost-effective than Neoprene, and is not as good for hot water and air. In addition, it may crystallize at low temperatures.
