Description

1,1'-[Hexamethylenebis(Oxy)]Bis[Pentabromobenzene] CAS NO 63618-49-5 is a high-performance brominated aromatic compound designed as a highly effective flame retardant additive. This product matters for manufacturers requiring superior fire safety without compromising the processing or mechanical properties of their polymer systems. It is primarily needed by the plastics, electronics, and construction industries for enhancing the flame retardancy of engineering thermoplastics, thermosets, and synthetic textiles.

Application

• Primary flame retardant for high-temperature engineering plastics such as PBT, PET, and polyamides (nylons).
• Additive for thermoset resins including epoxies and unsaturated polyesters used in circuit boards and composites.
• Flame retardant treatment for synthetic fibers and textiles in protective clothing and upholstery.
• Component in wire and cable insulation formulations to meet stringent fire safety standards.
• Used in electronic housings and connectors to achieve UL94 V-0 and other flammability ratings.
• Additive for adhesives and sealants requiring enhanced fire resistance.
