Lead Sheet + Flame Retardant Board is an innovative composite material combining the radiation shielding capabilities of high-purity lead sheet with the fire-resistant and sound-insulating properties of flame retardant board. This dual-function product is engineered for building decoration, medical facilities, and industrial settings where both radiation safety and fire protection are critical. The lead sheet component—made from lead ingots with ≥99.994% purity—effectively blocks ionizing radiation, while the flame retardant board (treated with non-toxic flame retardants) inhibits fire spread and reduces combustion risks. Bonded with high-strength adhesive, the composite structure ensures seamless integration of functions, making it a versatile choice for environments requiring multi-layered protection.

It integrates lead’s radiation-blocking ability with flame retardant board’s fire isolation function, eliminating the need for separate installations. This saves time, space, and costs while ensuring comprehensive safety.
The composite structure’s dense lead layer and flame retardant board work together to block sound transmission, making it perfect for hospitals, offices, and residential buildings where noise reduction is essential.
The lead sheet component resists acid, alkali, and chemical erosion, making the composite suitable for chemical processing plants, laboratory fume hoods, and industrial equipment linings.
Designed for building decoration, it can be installed on walls, roofs, and plywood. The lead sheet is typically placed above the flame retardant board to preserve both radiation shielding and fire-resistant performance without mutual interference.
Used to construct walls, doors, and observation windows in X-ray rooms, CT suites, and MRI facilities. It blocks radiation leakage while providing fire protection for sensitive medical equipment.
Ideal for healthcare settings where compliance with radiation safety and fire codes is mandatory.
Installed in kitchens, living rooms, and other flammable areas to enhance fire safety. The flame retardant board overcomes the flammability of ordinary wood boards, adding anti-corrosion and insect-proof benefits.
Used as sound-insulating partitions in commercial buildings, hotels, and residential complexes to improve indoor comfort.
Serves as anti-corrosion lining for acid-producing industrial storage tanks, pipelines, and chemical processing equipment.
Used as cable sheath insulation material, leveraging the lead sheet’s chemical resistance and the flame retardant board’s fire protection.
The recommended installation order is to place the lead sheet above the flame retardant board. This arrangement ensures the lead sheet’s radiation shielding and sound-insulating properties are fully utilized without compromising the flame retardant board’s ability to inhibit fire spread.
Yes. Both the lead sheet and flame retardant board are designed to withstand high humidity. The lead sheet’s corrosion resistance prevents rust or degradation, while the flame retardant board maintains structural integrity even in moist conditions. It is ideal for basements, laboratories, and coastal buildings.
No. The high-strength adhesive used to bond the lead sheet and flame retardant board is non-toxic and radiation-resistant. It meets international environmental standards, ensuring no harmful emissions or contamination, making it safe for medical and residential applications.
