One of the most important qualities you want in a custom gasket manufacturer is they have a comprehensive material selection and experience identifying the correct one for your application. Custom rubber gaskets are used in many types of service and under many different operating conditions. The material from which they are made must be carefully chosen to match those conditions.
A good custom gasket manufacturer can help guide you through this process. Here are just some of the many types of materials they might choose between.
Common Materials Seen in Custom Rubber Gaskets
Nitrile Rubber - Commonly used for petroleum based fluids, water, and air, Nitrile a good gasket material for a wide range of applications. It can handle temperatures from -15°F to 250°F.
Viton® - This fluorocarbon-based brand name rubber has resistance to many chemicals and strong acids, making it a good choice for use in challenging operational environments. It will also hand temperatures to 450°F.
Ethylene Propylene (EPDM) - EPDM is another gasket material primarily known for its resistance to hot water, low temperature steam, glycols, and phosphate ester fluids.
Neoprene - One of the most common rubber gasket materials used for cold water, some petroleum based fluids, and air applications.
PTFE (Teflon) - PTFE is inert and is widely used in a variety of chemical applications. It, and it’s proprietary filled PTFE material, Durlon 9000, is also made from FDA approved ingredients.
Silicone - Silicone has high temperature resistance, and is especially good in hot air applications to 500° F. Silicone is also available in a FDA approved version.
Polyurethane - Polyurethane has high resistance to abrasion and physical damage and should be considered for applications in abrasive environments.
