Categories of Materials for Gasket Manufacturing


Today’s gaskets represent some of the most innovative designs that are being developed in industry at the present time. When you are thinking about your next gasket project, consider that there are three general categories of materials that can be used during the process.

Silicone is one of the most widely used materials for gaskets. The primary benefit for using silicone is that it can tolerate very high temperatures that are present in the needs of the automotive, aerospace and industrial sectors. In addition to being heat resistant, silicone gaskets are also ideal for outdoor settings. The silicone used in outdoor gaskets is UV resistant, which means that it can be used outdoors without issues over time and exposure to weather. To strengthen silicone, other materials such as metal can be used as reinforcement. Silicone comes in both sponge and foam gasket specifications depending on your needs.

Another main type of material for gaskets includes metal. Metal gaskets can be processed using one type of metal or a mix of metals. Generally formed from stainless steel, brass, nickel, steel, copper or aluminum, these gaskets offer the highest level of thermal protection for parts. Metal gaskets also offer durability and tensile strength that can’t be duplicated by other types of materials. One note on metal gaskets: They do require additional compression in order to seal. That is why many multiple material gaskets are on the market today.

Finally, rubber and plastic gaskets are available as well. Rubber and plastics can deal with high pressures without permanent deformation while offering a high level of sealing between surfaces. The most common forms of rubber and plastic gaskets are Viton, nitril, neoprene, thermoplastic rubber, polyvinyl chloride and thermoplastic elastomers.
