Silicone flat Gaskets

Silicone flat gaskets are reliable sealing solutions known for their excellent resistance to extreme temperatures, flexibility, and suitability for applications requiring hygiene and food safety compliance. They are custom-cut from flat sheets of silicone material to fit specific flange shapes and sizes.
Key Features and Benefits
Extreme Temperature Resistance: Silicone offers superior performance across a broad range from approximately -75°C to +200°C (-100°F to +392°F), with special grades extending even further, making them ideal for high-heat environments.
Flexibility and Resilience: The material's elastic properties allow it to conform well to uneven surfaces to create effective seals and absorb vibrations, while maintaining its properties over time.
Hygiene and Food Safety: Many silicone grades are FDA-approved, non-toxic, odorless, and tasteless, making them ideal for sensitive applications in food processing, medical devices, and pharmaceuticals.
UV and Weather Resistance: Silicone offers excellent resistance to ozone, UV radiation, and general weathering, ensuring a long service life in outdoor applications.
Chemical Resistance: It provides good resistance to hot water, steam, some chemicals, and oils, although it is not recommended for use with concentrated solvents or petroleum-based fuels and oils.
Electrical Insulation: Silicone is an effective electrical insulator, suitable for various electronic and electrical sealing applications.
Common Materials and Properties
Silicone gaskets can be made from solid silicone rubber or sponge/foam silicone, depending on the required compression and sealing force.
Solid Silicone Rubber: Used for applications requiring a durable seal with specific compression characteristics and higher pressure resistance.
Silicone Sponge/Foam: Offers a softer, more conformable seal, ideal for low-force applications or where space variation needs accommodation.
Applications
Due to their robust properties, silicone flat gaskets are used across a wide range of industries:
Food and Beverage Processing: Widely used in pipes, equipment, and sealing components that require frequent cleaning and must comply with strict hygiene standards.
Medical and Pharmaceutical Equipment: Employed in medical devices, sterilizers (autoclaves), and lab equipment for their cleanliness, non-toxicity, and temperature resistance.
HVAC Systems: Used for sealing ducts, access panels, and components in heating and cooling systems where resistance to temperature fluctuations is needed.
Electronics and Lighting: Serve as weather seals and insulators in outdoor enclosures and lighting fixtures due to UV resistance and temperature tolerance.
Industrial Ovens and High-Temperature Equipment: Ideal for sealing industrial ovens, heat exchangers, and other machinery operating in high-heat environments.
