Our high-temperature resistant & flame-retardant silicone foam is a high-performance, industrial-grade flexible material, specially developed for high-temperature and flammable working environments, including industrial equipment, battery systems, electronic devices, automotive components, and aerospace accessories. Manufactured from high-purity platinum-vulcanized silicone raw materials, blended with high-efficiency halogen-free flame retardants and high-temperature resistant additives, it adopts precision closed-cell foaming and calendering molding technology. Targeted at the strict requirements of high-temperature resistance, flame retardancy, sealing, and long-term stability in harsh environments, this product fully complies with UL94 V-0, RoHS, REACH, IATF16949, and industrial high-temperature safety specifications. It effectively isolates high temperature, inhibits flame spread, seals gaps, cushions vibration, and provides reliable all-round protection for equipment and components operating in extreme high-temperature and flammable scenarios.
Core Performance & Structural Advantages
Featuring a uniform, dense closed-cell microstructure, flat surface, consistent thickness, and high resilience, this high-temperature resistant & flame-retardant silicone foam fits perfectly with equipment casings, component gaps, connection ports, and mating surfaces. It is soft and non-abrasive, avoiding scratches or extrusion damage to equipment and components, and specially optimized for high-temperature and flammable working conditions, delivering targeted, durable performance advantages:
-
Ultra-High Temperature Resistance: With excellent high-temperature stability, it adapts to extreme operating environments ranging from -60℃ to 250℃ (short-term resistance up to 300℃), remaining flexible without embrittlement at low temperatures and not softening, deforming, decomposing, or releasing toxic volatile substances at high temperatures. It effectively isolates heat transfer, reduces energy loss, and protects internal components from high-temperature damage.
-
UL94 V-0 High-Grade Flame Retardancy: Equipped with advanced halogen-free flame retardant formula, it complies with the strict UL94 V-0 flame retardant standard, featuring rapid self-extinguishing (≤3 seconds) without molten drips or toxic smoke emission during combustion. It forms a reliable fire barrier, effectively inhibiting flame spread and delaying fire escalation, maximizing the safety of equipment and operating environments.
-
IP67-IP68 Waterproof & Dustproof Sealing: The compact closed-cell structure forms a tight sealing barrier, reaching IP67-IP68 protection grade. It completely blocks the intrusion of rainwater, humid air, dust, and corrosive media, avoiding short circuits, component corrosion, and performance degradation caused by external impurities, ensuring the reliability of equipment operating in harsh environments.
-
High-Efficiency Shock Absorption & Vibration Damping: The high-resilience silicone material can absorb up to 85% of external vibration and impact energy, relieving extrusion and collision between equipment and components during transportation, installation, and operation. With a compression set ≤7%, it rebounds rapidly after long-term compression without permanent deformation, maintaining stable buffering performance even in high-temperature environments.
-
Superior Electrical Insulation: With a volume resistivity ≥10¹⁴Ω·cm, it delivers excellent electrical insulation performance, effectively isolating current, preventing electric leakage, short circuits, and electromagnetic interference, fully meeting the high safety standards of electrical equipment and components in high-temperature scenarios.
-
Precision Customization & Easy Assembly: Thickness ranges from 0.5mm to 50mm, with customizable length, width, and special profiles via precision die-cutting based on customer drawings. Dimensional tolerance is controlled within ±0.05mm, realizing a seamless fit with various equipment structures. The soft, non-stick texture enables quick positioning and assembly, boosting production line efficiency and reducing maintenance difficulty.
-
Eco-Friendly & Excellent Compatibility: Halogen-free, non-toxic, odorless, and free of heavy metals, fully complying with RoHS and REACH environmental protection standards. It has good chemical compatibility with metal, plastic, glass, and circuit components, with no adverse chemical reactions, and will not affect the performance and service life of equipment.

Precision Manufacturing & Strict Quality Control
Aiming at the high requirements of high-temperature resistance, flame retardancy, and stability in harsh environments, we implement the IATF16949 industrial-grade quality management system and carry out full-process quality control and multi-round rigorous testing to ensure product consistency and reliability:
-
High-Temperature & Flame-Retardant Raw Material Screening: Select high-purity platinum-vulcanized silicone raw materials, matched with special high-temperature resistant, halogen-free flame retardant, and anti-aging additives. All raw materials pass strict high-temperature resistance, flame retardancy, and environmental protection testing, ensuring adaptation to extreme working conditions.
-
Precision Foaming & Molding Process: Adopt closed-cell precision foaming and high-precision calendering technology to ensure uniform cell distribution and consistent thickness. High-precision die-cutting equipment processes products with smooth edges, no burrs, and no degumming, avoiding damage to equipment and components during assembly.
-
Comprehensive Performance Testing: Each batch undergoes 21 strict tests, including high-temperature resistance test, flame retardancy test, waterproof/dustproof test, compression resilience test, electrical insulation test, and dimensional accuracy test, with a factory qualification rate of 99.8%.
Precautions
1. Before installation, clean the contact surface thoroughly to remove dust, oil stains, water stains, and burrs, ensuring a tight fit between the silicone foam and the contact surface, and avoiding gaps affecting sealing, heat insulation, and flame retardant performance.
2. Do not stretch, bend, or cut the silicone foam forcibly during installation, so as not to damage the internal closed-cell structure and reduce its high-temperature resistance, flame retardancy, and buffering effects.
3. Avoid long-term direct contact between the product and strong acid, strong alkali, and corrosive chemical solvents, to prevent material corrosion and performance degradation, especially in industrial high-temperature scenarios with special media.
4. Store the product in a dry, cool, and ventilated environment, away from direct sunlight, high-temperature heat sources, and open flames, and avoid heavy pressure stacking to prevent deformation before use; the recommended storage temperature is 5℃-30℃.
5. Select the appropriate thickness, hardness, and specification according to the actual working temperature and gap size, and do not use specifications that do not match the design requirements, especially in ultra-high temperature scenarios.
6. During transportation and handling of equipment equipped with this silicone foam, avoid severe collision and excessive vibration to prevent displacement of the foam and failure of its functions.
7. Regularly check the appearance and performance status of the silicone foam in long-term high-temperature operation, and replace it in time if there is obvious aging, cracking, or deformation.
