\n Q1<\/span><\/p>\n
\n

What is SM150-FG1 designed for?<\/h3>\n

SM150-FG1 is designed for ultra-thin fire-barrier, sealing, and insulation applications where the material must behave like silicone rubber at room temperature but convert into a ceramic-like protective crust under extreme heat.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n Ultra-Thin Composite Direction<\/strong><\/p>\n

Suitable where the structure needs a very thin material with sealing capability plus thermal-barrier behavior.<\/p>\n<\/p><\/div>\n

\n Ceramifiable Silicone Behavior<\/strong><\/p>\n

At room temperature it behaves like silicone rubber; under high-temperature flame it sinters into a hard porous ceramic-like crust.<\/p>\n<\/p><\/div>\n

\n Fire Barrier + Thermal Insulation<\/strong><\/p>\n

Designed to provide fire resistance, flame retardancy, ablation resistance, and an insulating thermal barrier in one material system.<\/p>\n<\/p><\/div>\n

\n Protection-Oriented Use<\/strong><\/p>\n

Suitable for insulation, sealing, and fire-protection roles in battery packs and charging infrastructure.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n<\/section>\n

\n SM150-FG1 is an ultra-thin two-layer composite material uniformly coated with solid ceramifiable silicone rubber on one side. At room temperature, it retains the elasticity, sealing capability, and processability of silicone rubber. Under high-temperature flames or extreme overheating above 500\u00b0C, special additives react with the silicone matrix and sinter into a hard, porous ceramic-like crust, helping provide fire resistance, flame retardancy, ablation resistance, and an insulating thermal barrier.\n <\/p>\n
