Engineered for demanding industrial environments, our High-Temperature Resistant Silicone Foam Rubber Sheet delivers exceptional reliability, safety, and performance. By combining advanced material science with precise manufacturing processes, this material serves as a foundational component for thermal management, sealing, and structural protection across multiple sectors.
Operating continuously within a demanding thermal spectrum of -60℃ to 220℃, the structural integrity of this foam sheet remains uncompromised. It resists embrittlement in freezing conditions and prevents degradation or melting under intense heat. This thermal stability ensures uninterrupted cushioning and sealing performance, drastically reducing maintenance cycles for automotive engines, aerospace components, and heavy-duty industrial machinery.
Supported by a dedicated team of R&D engineers, we offer comprehensive OEM and ODM solutions that go beyond basic custom cutting. Whether you require complex geometries derived from CAD drawings, specific density adjustments, or unique thickness formulations, our precision processing guarantees exact dimensional tolerances. This plug-and-play readiness eliminates secondary processing on your assembly line, accelerating production schedules.
To streamline integration into your manufacturing workflow, these sheets can be equipped with premium 3M self-adhesive backing. The industrial-grade adhesive forms an immediate, unyielding bond with metals, plastics, and composites. This peel-and-stick functionality not only speeds up the assembly of electronic enclosures and battery packs but also ensures the gasket remains firmly anchored under continuous mechanical vibration.
Characterized by a highly resilient closed-cell structure, the material acts as an impenetrable barrier against dust, moisture, and environmental contaminants. Simultaneously, its inherent elasticity absorbs kinetic energy, dampening mechanical vibrations and acoustic noise. The tactile compression recovery ensures a permanent, watertight seal even after thousands of compression cycles.
Safety is paramount in electrical and vehicular applications. Our silicone foam achieves strict flame-retardant ratings, featuring distinct self-extinguishing properties. In the event of a thermal runaway or electrical short, the material resists ignition and prevents the spread of flames, providing a critical window of safety for personnel and protecting expensive adjacent components from catastrophic fire damage.
The microscopic closed-cell architecture traps air effectively, creating a formidable barrier against thermal conductivity. This insulation capability is paired with excellent vapor resistance, completely blocking moisture ingress. It prevents condensation buildup within sensitive electronic housings and maintains stable internal temperatures for sensitive equipment operating in humid or thermally volatile environments.
Manufactured with a strict commitment to environmental responsibility, the formulation is entirely non-toxic, odorless, and free from fibrous dust. The production process utilizes zero ozone-depleting substances like CFCs or HCFCs. Furthermore, the material is naturally anti-microbial and resists mold growth, meeting the most rigorous global environmental and safety directives for cleanroom and consumer-facing applications.
To guarantee that every sheet meets exact engineering specifications, we implement a 100% traceability mechanism spanning from raw material warehousing to final product dispatch. Our rigorous quality control protocols ensure that the physical and electrical properties listed below remain highly consistent across every batch, providing reliable data for your structural calculations and procurement evaluations.

The versatility and durability of our silicone foam sheet make it an indispensable material for engineers and product designers across a multitude of demanding industries.
Within the automotive sector, this material is engineered to endure the harsh realities of engine compartments and undercarriages. It acts as a resilient gasket for lighting enclosures, HVAC systems, and dashboard assemblies. By effectively absorbing road vibrations and sealing out corrosive fluids and dust, it significantly prolongs the lifespan of critical automotive components while enhancing cabin acoustics for passenger comfort.
Precision electronics require absolute protection from environmental variables. Our foam sheets are widely utilized as LCD screen gaskets, PCB vibration dampers, and enclosure seals for outdoor telecommunication base stations. The material's high volume resistivity (10¹⁴ Ω·cm) ensures superior electrical insulation, safeguarding delicate circuitry against moisture-induced short circuits and mechanical impacts.
Industrial manufacturing environments expose machinery to continuous friction, heat, and chemical exposure. Applied as structural buffering pads or pipeline insulation, the foam sheet dampens the deafening noise of automation equipment and absorbs the kinetic shock of heavy presses. Its resistance to ozone and aging ensures that the seals do not crack or degrade, minimizing costly factory downtime.
As the new energy sector rapidly expands, thermal management within lithium-ion battery packs is critical. The foam is deployed as compression pads between battery cells, accommodating expansion and contraction during charge cycles while providing essential thermal insulation. Its flame-retardant properties act as a vital safety barrier, preventing thermal propagation across the energy storage device.
For appliances generating intense heat, such as commercial ovens, coffee machines, and industrial steamers, standard rubber quickly fails. Our non-toxic, heat-resistant silicone foam maintains a perfect hermetic seal at 220℃, preventing steam leakage and ensuring energy efficiency. Its compliance with rigorous safety standards makes it the preferred choice for applications in close proximity to food and water.
To maximize the operational lifespan and sealing efficacy of the silicone foam sheet, we recommend following this standardized preparation and application procedure during assembly:
Step 1: Specification Assessment. Prior to installation, verify the thickness, density, and operating temperature requirements of your specific application. Ensure the chosen sheet accommodates the expected compression ratio (typically 20% to 50% for optimal sealing) without over-stressing the material.
Step 2: Surface Preparation. The target substrate (metal, plastic, or glass) must be meticulously cleaned. Remove all residual oils, dust, moisture, and chemical solvents using an appropriate industrial cleaner. A completely dry and sterile surface is mandatory for maximum adhesive bonding.
Step 3: Precision Application. If utilizing the optional 3M self-adhesive backing, carefully peel away the release liner. Apply the foam sheet with firm, even pressure across the entire surface area to eliminate trapped air pockets. Avoid excessive stretching or sharp bending during placement, as this can induce structural tension and reduce long-term durability.
Step 4: Storage & Maintenance. For inventory management, store unapplied rolls or custom-cut pads in a climate-controlled, dry environment. Keep the material shielded from direct UV exposure and away from direct heat sources prior to installation to preserve the integrity of the adhesive backing and the foam's cellular structure.
