A gasket may be a relatively inexpensive component, but when it fails, the damage can be catastrophic. That's why SUNWELL helps customers view the entire assembly of a part to ensure the gasket fits well with all other components. In general, silicone rubber is an ideal material for custom gaskets. Its ability to maintain dimensional stability within tight tolerances, protect sensitive components, and keep out contaminants and moisture makes silicone rubber one of the most common gasket and sealing materials.
Properties of silicone rubber gaskets
Silicone rubber is the main force, providing customers with a wide range of development solutions. Silicone formulations are available to suit a variety of applications and budgets. It is generally resistant to one of the widest ranges of temperature extremes, with certain silicone compounds functioning well in temperatures ranging from -67 to 572 degrees Fahrenheit. It also resists the sun's powerful ultraviolet rays and atmospheric ozone, both of which can degrade weaker materials. Silicone rubber has broad chemical resistance, making it non-reactive with many other chemicals found in many environments. SUNWELL can often provide general silicone chemical resistance information to support customers in their material selection process.
When used as a gasket material, silicone rubber forms a high-performance seal that prevents leakage between two mating parts in an assembly.
With all these advantages, it's no surprise that silicone rubber gaskets are widely used in industries ranging from aerospace and transportation to food and construction. Silicone formulations come in cellular, solid and reinforced configurations, giving customers the choice of applications requiring soft, medium or hard rubber.
Silicone Rubber Gaskets for Aerospace
In general, silicone rubber's resistance to extreme temperatures, ultraviolet light, and ozone makes it an ideal material for gaskets on aircraft, space shuttles, and other air and space equipment. Aerospace applications require components that will not fail in the field, even under stress from the elements and external environment. This is especially true when these applications are manned.
Silicone rubber gaskets are used in a variety of aerospace components, from engine gaskets to ventilation ducts. In these applications, testing has proven them ideal components for door, window, HVAC and dashboard seals. Silicone rubber gaskets may also perform well in terms of vibration dampening and heat insulation.
Transportation uses of silicone rubber gaskets
Silicone rubber is durable, stable in extreme environments, and resistant to environmental stress. These capabilities are as useful on the ground as they are in the air. Silicone rubber gaskets are ideal for use on personal, commercial and industrial vehicles, heavy machinery, and buses and trains.
Silicone rubber gasket dampens vehicle vibrations and provides a high-performance seal for the radiator. In mass transit applications, they provide vibration damping as well as inner door seals and seals around electrical enclosures, protecting the vehicle and its occupants from the elements.
Commercial Applications of Silicone Rubber Gaskets
In the general commercial field, silicone rubber gaskets have a wide range of applications. The construction industry uses silicone rubber gaskets as seals in HVAC systems and doors. Certain types of silicone rubber also make excellent shock pads. In the food industry, gaskets can be found on food processing machinery and industrial oven seals.
