Flame - retardant liquid silicone foam is a high - performance engineered material. It is developed by introducing specific flame - retardant additives during the precise manufacturing of liquid silicone rubber (LSR). This unique process endows it with a stable cellular structure while ensuring excellent fire - resistant properties.
This material can maintain its integrity within a wide temperature range, from - 40°C to 250°C. It combines the inherent advantages of silicone, like chemical resistance, with remarkable flame - retardancy, meeting standards such as UL94 V - 0 or HB. Its resilient foamed structure offers good compressibility and quick recovery. Additionally, it provides effective vibration damping and thermal insulation.
These features make flame - retardant liquid silicone foam an ideal choice for applications where fire safety, temperature resistance, and reliable performance are crucial. It's widely used in electronics manufacturing for safeguarding sensitive components from fire risks, in construction for fire - proof insulation in walls and ceilings, and in transportation, such as railway carriages and aircraft interiors, to enhance safety and comfort while maintaining a light weight.
Flame-retardant Liquid Silicone Foam
This high-performance Flame-retardant Liquid Silicone Foam by Senma is crafted using advanced liquid silicone rubber (LSR) technology with integrated flame-retardant additives, forming a fire-resistant yet flexible material with reliable sealing capabilities. Our specialized manufacturing process creates a stable, uniform cellular structure that offers excellent compressibility (>60% recovery), effective thermal insulation, and consistent performance across a broad temperature spectrum (-40°C to 250°C).
Boasting an optimized density range of 0.3-0.6g/cm³ and customizable hardness, this material excels in applications demanding fire safety, temperature resilience, and secure sealing—such as electronics component protection, construction fireproof insulation, and transportation interior safety systems. The closed-cell structure ensures lasting performance while retaining silicone's inherent chemical resistance and compliance with UL94 V-0/HB flame-retardant standards.
