3732 fiberglass cloth is a medium-to-heavy weight industrial E-glass fabric used for fire protection, heat insulation, welding protection, and coated fabric production. Its dense woven structure helps provide stable strength and effective heat shielding in demanding industrial environments.
Compared with lighter fiberglass fabrics, 3732 offers better durability and protection for welding blankets, fireproof curtains, thermal insulation systems, and industrial safety covers. It can also be coated with silicone, vermiculite, acrylic, PU, PTFE, or laminated with aluminum foil for enhanced performance.
Non-combustible fiberglass material: E-glass fiberglass does not support combustion, making it suitable for fire protection systems.
High temperature resistance: Continuous working temperature up to approx. 550°C and short-term exposure up to approx. 700°C.
Strong and durable construction: Approx. 430 g/m² fabric weight provides good tensile strength, tear resistance, and long service life.
Excellent thermal insulation: Helps reduce heat transfer and protect equipment, work areas, and personnel.
Chemical and corrosion resistance: Suitable for many industrial environments exposed to oils, mild acids, alkalis, and chemicals.
Flexible and easy to fabricate: Can be cut, sewn, coated, laminated, and processed into finished fireproof products.
Ideal coating substrate: Compatible with silicone, vermiculite, acrylic, PU, PTFE, graphite, and aluminum foil lamination.

RUISHUN 3732 fiberglass cloth is widely used in industrial fire prevention, thermal protection, and high-temperature insulation systems.
Welding blankets, fire blankets, and spark protection covers
Fire curtains, fire barriers, and smoke barriers
Thermal insulation jackets and removable insulation covers
Heat shields and fireproof protective layers
Industrial furnace, boiler, and equipment protection
Fire-resistant partitions and industrial safety screens
Base fabric for silicone coated, vermiculite coated, acrylic coated, PU coated, PTFE coated, and aluminum foil laminated fiberglass materials
It provides protection against sparks, molten metal splash, radiant heat, flame exposure, and high-temperature surfaces in workshops, shipyards, power plants, metal fabrication facilities, and industrial maintenance environments.
