Silicone Coated Fiberglass Welding Blanket
Safeprotex offers high-performance silicone coated fiberglass welding blankets, engineered for toughness, flexibility, and reliable thermal protection in industrial environments.
Constructed from a durable fiberglass substrate and coated with high-grade silicone rubber, silicone coated welding blankets serve as effective thermal barriers, spark shields, and equipment covers for medium to heavy-duty welding operations.
Silicone coated blankets withstand intermittent temperatures up to 1022°F (550°C), extinguish sparks in ≤1.5 seconds, and provide zero flame penetration in accordance with ASTM D4357 standards.
Standard thicknesses and sizes are available, with custom options provided upon request. All products comply with Mil-Y-1140C and are certified to NFPA 701 and UNE EN 1869:2021 specifications.

Applications:
Safeprotex silicone coated fiberglass welding blankets are designed for medium-duty thermal protection and are suitable for a wide range of industrial settings where sparks, spatter, and light slag are present.
Common applications include:
Welding Curtains: Serve as protective barriers in welding bays to prevent spark spread.
Heat Shields: Shield equipment and nearby materials from radiant heat.
Thermal Curtains: Partition high-temperature zones in industrial facilities.
Fire Blankets: Used for emergency flame suppression or prevention.
Removable Insulation Covers: Protect pipes, valves, and flanges where temporary insulation is required.
Expansion Joints & Supply Tarps: Provide heat-resistant sealing and protective covering.
These blankets can also be laid over horizontal surfaces to protect floors, workstations, or machinery from thermal or welding debris.
