When pipes, boilers, fuel tanks and more need to be joined together, what’s the best way to prevent liquid or gas from leaking?
The answer: a gasket.
At Breiner Non-Metallics, we make a lot of gaskets. Our parts make their way around the world, helping manufacturers, mechanical contractors and more maintain the integrity of their equipment.
Many different non-metallic materials can be used in gasket manufacturing, with each presenting their own unique advantages and abilities under different circumstances. The following examples are some of the most common and versatile non-metallic materials we use for gasket making.
It’s a popular choice for a reason — natural rubber is a good all-around, general-purpose gasket material. While it shouldn’t be used with fuels, oils or solvents, natural rubber is incredibly water resistant and works very well with metal surfaces. Natural rubber is great for use with water pumps and pipes, also adding good shock and vibration resistance qualities.
Flexibility and weather resistance plus electrical insulating properties make silicone rubber a very popular choice for gasket material. Silicone maintains high performance at extreme temperatures, remaining functional between negative 60 and more than 400 degrees Fahrenheit. Its versatility makes silicone rubber ideal for a wide variety of applications, including pharmaceutical and food processing environments.
Typically used in marine and other outdoor applications, neoprene rubber has the ability to resist moderate levels of sunlight, ozone and other weather elements, as well as greases, fats and oils. Neoprene rubber can also be used in refrigerant applications. This polymer is able to withstand a wide range of temperatures, from negative 31 to 250 degrees Fahrenheit.
A synthetic rubber that can be in both open and closed cell forms and is great at repelling dust, water and moisture, neoprene sponge gaskets are well suited for industrial settings using fuel, oil and other chemicals. Its cellular nature gives neoprene sponge superior absorption, insulation and compressive properties. Most closed cell neoprene sponges can meet UL 94HF-1 flame ratings.
Flexible as well as oil- and solvent-resistant, cork is a popular material for gasket manufacturing due to its high compressibility and flexibility. A renewable, sustainable material as it comes from the bark of the cork oak tree, cork is naturally impermeable, buoyant, elastic and fire retardant. It’s typically used as gaskets for oil and fuel pumps as well as around electrical gear.
Introduced to fill the void left when asbestos was discovered to be a dangerous material, compressed non-asbestos gaskets combine great strength plus high resistance to heat, water, gases, oils, fuels and chemicals. These types of gaskets are at home in hard-to-seal applications, such as in the presence of steam and sustained high temperatures.
There is no one solution to any particular application. Some materials perform admirably in a variety of situations while some excel in specific environments while lacking in others. No matter what you require out of your next batch of gaskets, our experts at Breiner Non-Metallics can help you choose the perfect material for your needs.
