Welding Fire Blanket & Heat Insulation

Purpose & best fit

Woven fiberglass welding blanket for general MIG/TIG/Arc welding, abrasive cutting, and hot work permit scenarios where spatter < 760°C. Lay on floor, hang as curtain, or drape over flammable equipment. Class A spec range for typical light-spatter work (certifications sourced per project requirement).

Working principle

E-Glass fiber woven plain/leno blocks ignition via high melt point — 600-760°C sparks land and quench instantly without scorch, melt, or toxic smoke. Reusable 50-100 cycles when stored dry.

Purpose & best fit

High-Silica fabric (SiO₂ ≥ 96%) with vermiculite coating for heavy welding, plasma/oxy-fuel cutting, gouging, and slag splatter at 760-1,090°C. Tolerates direct flame exposure briefly. Primary choice for shipyards, pipeline construction, and heavy industry.

Working principle

Tightly-woven high-silica fibers + vermiculite (expandable mica mineral) coating that expands under high heat, forming an insulating layer preventing scorch. Vermiculite also reduces smoke and boosts flame retardancy beyond uncoated silica.

Purpose & best fit

Fiberglass cloth with double-sided silicone coating (translucent orange/dark-green/yellow) used as welding bay curtains — filters UV arc-flash radiation + blocks spatter simultaneously. Long-life because silicone prevents fiber shedding; smooth, non-irritating surface for operators in frequent contact.

Working principle

Silicone elastomer fully encapsulates fiberglass fabric on both sides — operators can handle, roll, hang it without itchy fiber dust. Translucent colors filter UV (280-400 nm) from welding arcs while passing enough visible light for supervisor visibility. Withstands spatter ≤ 500°C.

Purpose & best fit

Aluminosilicate ceramic fiber blanket — highest temperature rating in the welding blanket family. For molten metal splash, foundry operations, billet/ingot quenching, forge work, and hot work permits with slag > 1,090°C. Floor cover during metal pouring + billet drape during transport.

Working principle

Aluminosilicate ceramic fibers (Al₂O₃ 45-50% + SiO₂ 50-55%) — refractory rated to 1,260°C continuous. Fiber structure traps air → low thermal conductivity → slow heat transfer. Chemically inert against most molten steel/aluminum/copper.
