Custom High Temperature Resistant Silicone Gasket
Silicone gasket is a sealing device made from silicone rubber material that is used to create a tight and reliable seal between two or more surfaces. Silicone gaskets are designed to withstand a wide range of temperatures, chemicals, and environmental conditions, making them suitable for various applications across different industries.
Material: Silicone gaskets are typically made from high-quality silicone rubber. Silicone rubber is a synthetic elastomer known for its excellent physical properties, including flexibility, durability, and resilience. It is resistant to extreme temperatures, chemicals, UV radiation, moisture, and weathering, making it ideal for sealing applications.

Features
Design and Construction: Silicone gaskets come in various shapes, sizes, and configurations to suit different sealing requirements. They can be manufactured as flat gaskets, O-rings, flange gaskets, custom-molded gaskets, or extruded profiles. The design and construction of the gasket depend on the specific application and the type of sealing needed.
Sealing Function: The primary purpose of a silicone gasket is to create a secure and leak-proof seal between two mating surfaces. The gasket fills the irregularities and gaps between the surfaces, preventing the escape or ingress of fluids, gases, dust, or other contaminants. This sealing function helps maintain pressure integrity, prevent leakage, and protect the components or systems being sealed.
Temperature Resistance: Silicone gaskets exhibit excellent temperature resistance properties. They can withstand both high and low temperature extremes without losing their physical properties or compromising the seal. Silicone gaskets can withstand temperatures ranging from sub-zero temperatures up to several hundred degrees Celsius, depending on the specific formulation and grade of silicone rubber used.
Chemical Resistance: Silicone gaskets offer good resistance to a wide range of chemicals, including acids, bases, solvents, oils, and many other substances. This chemical resistance ensures that the gaskets maintain their integrity and sealing properties even when exposed to aggressive or corrosive environments. However, it is important to consider the compatibility of the specific silicone grade with the intended chemicals to ensure optimal performance.
Compression and Flexibility: Silicone gaskets are known for their excellent compression and flexibility characteristics. They can be compressed and deformed to fill gaps and conform to irregular surfaces, ensuring a tight and effective seal. The flexibility of silicone gaskets allows them to adapt to changes in temperature, pressure, or movement without losing their sealing capabilities.
Applications
Silicone gaskets find applications in a wide range of industries, including automotive, aerospace, electronics, medical, food and beverage, HVAC (Heating, Ventilation, and Air Conditioning), and many others. They are used in engines, pumps, valves, electrical enclosures, pipe connections, sealing lids or covers, and various other equipment or systems that require reliable sealing.
