Silicone Coated Fiberglass Welding Blanket
1. Product Overview
Silicone coated fiberglass welding blanket is an engineered safety barrier constructed from high-density woven E-glass cloth coated with industrial flame-retardant silicone rubber. The silicone encapsulation seals the fiberglass fibers to prevent mechanical skin irritation and fiber shedding while shedding oil, water, and grease. Engineered specifically for hot work zones, the dense composite structure stops high-velocity grinding sparks, welding spatter, and molten slag from penetrating or igniting surrounding equipment, sensitive machinery, and personnel areas. Blankets are finished with reinforced perimeter hems stitched with high-temperature fiberglass or aramid thread and fitted with heavy-duty brass grommets for secure rigging.
