In high-safety industries such as new energy batteries, new energy vehicles, electronic electrical engineering and industrial equipment, the flame retardancy of sealing and cushioning materials is a core safety indicator. Ordinary foam materials are prone to combustion, dripping and toxic gas release in case of open fire, bringing huge potential safety hazards. Flame-retardant silicone foam is a high-performance functional foam material specially developed for safety-critical scenarios, combining the excellent resilience, sealing and aging resistance of silicone foam with ultra-high flame retardant performance. Tengye provides premium flame-retardant silicone foam products, made of high-purity flame-retardant silicone raw materials and professional foaming technology, to deliver safe, stable and long-lasting sealing, cushioning and fire protection for various harsh and high-safety-demanding applications.
Flame-Retardant Silicone Material & Professional Foaming Technology
Our flame-retardant silicone foam adopts imported high-performance flame-retardant silicone raw materials, with halogen-free, low-smoke and non-toxic environmental protection formula, and is prepared by advanced closed-cell or open-cell foaming process, forming a uniform and dense porous internal structure. We strictly control the foaming ratio and material ratio, ensuring that the product has excellent flame retardancy while retaining the superior physical properties of silicone foam, and can be customized into industrial grade, automotive grade and medical grade according to application scenarios.
This special flame-retardant silicone foam has a wide operating temperature range of -60℃ to 230℃, maintaining soft flexibility and stable resilience in extreme high and low temperature environments, without hardening, cracking or deformation. It has strong chemical corrosion resistance, resisting acid, alkali, oil, battery electrolyte and organic solvent erosion, as well as outstanding UV resistance, ozone resistance and humidity resistance, suitable for long-term use in harsh outdoor and industrial environments. All products comply with RoHS 2.0, REACH and other international environmental protection standards, and the core flame retardant performance meets UL 94 V-0 certification, with authoritative third-party test reports such as SGS and Intertek to escort product safety.
Core Performance Advantages of Flame-Retardant Silicone Foam
Our flame-retardant silicone foam integrates multiple high-performance advantages, breaking through the defects of traditional foam materials, and fully meeting the dual needs of safety protection and functional application in various industries:
-
Ultra-High Flame Retardant Performance: Meets UL 94 V-0 top-level flame retardant standard, self-extinguishing immediately after leaving the fire, no molten dripping, no toxic and harmful gas release, effectively blocking the spread of fire, greatly improving the safety factor of equipment and components.
-
Excellent Sealing & Waterproof: Dense closed-cell structure can reach IP67-IP68 high protection rating, effectively isolating moisture, water vapor, dust and sediment, ensuring long-term stable sealing effect even in humid and underwater environments.
-
High Resilience & Low Compression Set: With exceptional rebound ability, the compression set is ≤5% after long-term compression, maintaining tight fitting and sealing performance under continuous pressure, avoiding failure caused by permanent deformation.
-
Superior Shock Absorption & Cushioning: The porous foam structure can efficiently absorb vibration, impact and noise, reduce external force damage to precision components, and enhance the stability and service life of equipment.
-
Long-Term Aging Resistance: Resists long-term environmental erosion and temperature cycle changes, maintaining stable performance for 8-10 years, far exceeding the service life of ordinary PU foam, EVA foam and rubber materials.
-
Soft & Easy to Process: Light weight, good flexibility and fit, can be cut, die-cut and molded at will, adapting to irregular surfaces and complex structural gaps, suitable for automated assembly and manual installation.

Precautions for Use
To ensure the performance and service life of flame-retardant silicone foam, and give full play to its flame retardant and sealing effects, please pay attention to the following points during installation and use:
-
Before installation, clean the bonding surface thoroughly to keep it dry, smooth, free of oil, dust and burrs, so as to ensure the fitting effect of the foam.
-
Control the compression ratio reasonably during installation, generally controlled at 30%-50%, avoid excessive compression to prevent permanent deformation, which will affect sealing and flame retardant performance.
-
Store the product in a cool, dry and ventilated environment, avoid long-term exposure to strong sunlight, high temperature heat sources and open flames, and keep away from flammable and corrosive chemicals.
-
Select the appropriate product specifications, thickness and flame retardant grade according to the actual application scenario, equipment structure and safety standard requirements.
Strict Quality Control System
We adhere to the principle of "safety first, quality supreme", and implement a full-process strict quality control system from raw material procurement to finished product delivery, ensuring that each batch of products meets international safety and performance standards:
