Description

Tetrabromobisphenol-A-Polycarbonate is a high-performance brominated flame retardant oligomer derived from tetrabromobisphenol A (TBBPA). This compound matters for its exceptional ability to impart flame retardancy to engineering thermoplastics while maintaining good thermal stability and mechanical properties. It is primarily needed by manufacturers in the electronics, automotive, and construction industries seeking to enhance the fire safety of polycarbonate resins and their blends to meet stringent international safety standards.

Application

  • As a reactive or additive flame retardant for polycarbonate (PC) resins and PC/ABS blends.
  • Enhancing fire resistance in components for the electronics and electrical (E&E) industry, such as connectors, housings, and covers.
  • Improving the flame retardancy of materials used in automotive interior and exterior parts.
  • Formulation of flame-retardant compounds for construction materials and insulation.
  • Use in specialty engineering plastics requiring UL94 V-0 or V-2 ratings.
  • Potential application in wire and cable coatings for improved safety performance.
