Description

Tbbpa Carbonate Oligomer Bc58 CAS NO 71342-77-3 is a brominated flame retardant oligomer derived from tetrabromobisphenol A. This compound is engineered to provide excellent thermal stability and flame-retardant efficiency, making it a critical additive for enhancing fire safety in polymer materials. It is primarily utilized by manufacturers in the electronics, construction, and automotive industries who require high-performance, halogenated flame retardants that meet stringent safety regulations without significantly compromising the physical properties of the base polymer.

Application

• As a reactive or additive flame retardant in epoxy resins for printed circuit boards (PCBs) and electronic encapsulants.
• Incorporation into polycarbonate blends and alloys to achieve UL94 V-0 and V-1 ratings for components in consumer electronics and electrical housings.
• Use in thermoplastic polyesters (PBT, PET) for connectors, switches, and other electrical parts requiring flame resistance.
• Formulation of flame-retardant coatings and adhesives for construction materials and automotive interiors.
• Modification of engineering plastics used in appliances, tools, and industrial equipment to comply with international fire safety standards (e.g., IEC, UL).
• Potential use in wire and cable insulation compounds to improve fire performance.
