High-Temperature Resistant Flexible Sealing Die Cut Silicone Sponge Gaskets

 

 

Overview:  

A silicone sponge gasket is a flexible, compressible sealing material made from silicone rubber with a porous, sponge-like structure. It combines the excellent thermal stability, chemical resistance, and durability of solid silicone with the added benefits of lightweight cushioning, superior compression recovery, and effective shock absorption.  

 

 Key Features & Benefits:  

- Temperature Resistance – Withstands extreme temperatures from -60°C to +200°C (-76°F to +392°F), making it ideal for high-heat environments.  

- Closed-Cell Structure – Resists water, dust, and air infiltration while maintaining a tight seal.  

-Compression Recovery – Excellent resilience with minimal permanent deformation, ensuring long-term sealing performance.  

- Chemical & Weather Resistance – Resists UV radiation, ozone, oils, and many chemicals, suitable for indoor and outdoor use.  

- Soft & Lightweight – Low density reduces weight while providing cushioning and vibration damping.  

- Customizable – Available in various thicknesses, densities, colors, and can be die-cut, extruded, or molded to precise shapes.  

 

 Common Applications:  

- Electronics & Electrical Enclosures – EMI/RFI shielding, waterproof seals for control panels, junction boxes.  

- Automotive & Aerospace – Engine gaskets, battery seals, vibration damping in vehicles and aircraft.  

- HVAC & Construction – Weatherproofing for doors, windows, and ductwork.  

- Industrial Machinery – Sealing for pumps, compressors, and high-temperature equipment.  

 

 Available Options:  

- Material Grades: Standard, flame-retardant (UL94 V0)

- Shapes & Sizes: Sheets, strips, rolls, custom die-cut or extruded profiles.  

- Colors: Black, white, red, gray, and other custom colors.  

 

 Why Choose Silicone Sponge Gasket?  

Unlike solid silicone or foam rubber, silicone sponge gaskets offer a unique balance of compressibility, resilience, and environmental resistance, making them a superior choice for demanding sealing applications.
