Gasket seals play an essential role in protecting mechanical systems from damage by environmental conditions like rain, dust, or other debris. There’s a wide variety of gasket materials, and their selection depends mainly on the nature of sealing needs. Other than durability, other critical factors influencing the choice of gasket material are performance expectations and environmental conditions. At Gorilla gasket manufacturing company, we understand the uniqueness of every sealing need, and that’s why we offer limitless customization options.
Rubber Gasket Material Types
Temperature is usually one of the key criteria for selecting gasket materials. Rubber can withstand a wide range of temperature conditions (between -50ºC to +120ºC), making it one of the most important sealing materials.
Different applications work optimally with different rubber variations. For instance, neoprene or EPDM are best suited for applications involving water use, while Viton® based gaskets work best in high-temperature conditions. Let’s take a look at some of the most popular rubber materials;
Neoprene, also known as chloroprene, is a synthetic and versatile rubber used in various industries. It is highly resistant to chemicals, oil, sun, ozone, and weathering hence its wide range of applicability. It can accommodate temperatures between -20ºC to +110ºC and is commonly used in environments with water, whether salty or fresh.
2. Nitrile Rubber (Buna-N)
It’s also referred to by the trade names Europrene, Nepal, and Krynac and is well known for its excellent resistance to a wide range of chemicals, oil, and fuel. It also boasts an excellent impermeability to gases, a reasonable recovery rate, and a high resistance to abrasion due to wear and tear.
3. Ethylene Propylene Diene Monomer (EPDM)
It’s a copolymer of ethylene, propylene, and a little diene monomer. It offers superb resistance against weathering, aging, ozone, and heat. It has also proven to have good electrical insulation and low-temperature properties. EPDM is widely used in applications that involve different water temperatures. The automotive industry is its biggest market. They use EPDMs to manufacture O-rings and gaskets, radiator hoses, window and door seals, and many more. EPDM works optimally between a temperature range of -45°C to +150°C.
4. Viton® FKM
It is made up of a family of fluoroelastomer materials and is best known for its ability to withstand very high temperatures. The automotive industry has incorporated it for use in a variety of car parts, from O-rings to seals. Chemical industries have also adopted this gasket material due to its resistance to fuel and oil. Viton® also has a good ozone resistance and impermeability to gases. It’s suitable for use within a temperature range of -12°C to +315°C.
It’s a rubber-like material composed of silicone. It’s well known for its good adaptability to extreme temperatures ranging from -55°C to + 300°C. It can withstand harsh environmental conditions without any change in its physical properties. It boasts a high resistance to damages from aging, weathering, UV, water, and oxygen.
All the rubber materials mentioned above are suitable gasket materials, and as we had said, unique applications require different material types.
