There are a variety of materials that can be used to make gaskets. When preventing leaks is the objective, it’s very important for these materials to be reliable and long lasting. But before determining the right material for your project, you must first consider how your gasket will be used. Here are some things to think about before deciding what material to use:
- What application will the gasket be used in?
- What temperature range will the gasket be used in?
- Are there any potential chemicals that may come in contact with the gasket?
- What type of system pressure will the gasket need to endure?
Once you have determined the use for your gasket, the next step is figuring out the type of material that will best serve this purpose.
There are many types of materials we use at Expert Gasket & Seal to make gaskets. Here are a few popular materials to consider for your next project.
Rubber Gasket Materials
- Silicone rubber is a versatile material that is effective in high and low temperature environments. A silicone rubber gasket will prevent oxygen from penetrating as well as resist a lot of potential problems, like ozone, UV rays and inclement weather.
- Viton rubber has an exceptionally broad range of chemical resistance making Viton a perfect option for most applications involving oils, fuels, acids, this material boast excellent resistance to oxidation, ozone, and UV exposure.
- Propylene Diene Monomer (EPDM) rubber is used in hot water and steam conditions. EPDM rubber is also used with glycol-based brake fluids and is known for great resistance to ozone, aging and a range of weather conditions.
For compressed gasket materials, here are a couple of frequently used materials in this gasket category.
- Durlon® 8500 is a green colored NBR binder/Aramid-Inorganic fiber compressed sheet. This would be a great choice for steam, natural gas and a number of petroleum-based fluids. It will perform in temperatures as low as -100 degrees Fahrenheit and as high as 700 degrees Fahrenheit. The continuous max temperature is 548 degrees Fahrenheit.
- Durlon® 8400 is a gold colored NBR binder/Phenolic fiber sheet. This type of material is a popular choice when a wide pH range is needed. It’s an excellent choice in chemical, pulp and paper and other industrial applications. This material will perform in temperatures as low as -100 degrees Fahrenheit and as high as 800 degrees Fahrenheit. The continuous max temperature is 554 degrees Fahrenheit.
- Durlon 9000 is extensively used in chemical, pulp and paper, food and beverage, and the railroad tanker industry.
