For professionals in the chemical and manufacturing sectors, having detailed knowledge of key chemical compounds is essential for product innovation and quality assurance. Tris(2,3-dibromopropyl)isocyanurate, identified by CAS number 52434-90-9 and commonly known as TBC, is a highly regarded brominated flame retardant. This expert guide provides a comprehensive look at TBC's properties, its critical applications in polymers and textiles, and crucial considerations for sourcing this vital additive.

Understanding TBC (CAS 52434-90-9): Properties and Mechanism

TBC is a white crystalline powder with a molecular formula of C12H15N3O3Br6. Its chemical structure, featuring six bromine atoms, is key to its efficacy as a flame retardant. When exposed to heat or flame, TBC undergoes decomposition, releasing bromine radicals. These radicals act in the gas phase to quench the flame, interrupting the chain reactions that propagate fire. This mechanism makes TBC a potent agent for enhancing the fire safety of various materials.

Key properties that make TBC highly desirable include:

  • High Bromine Content: The presence of a significant amount of bromine atoms ensures efficient flame inhibition.
  • Melting Point: Typically in the range of 105-115°C, allowing for incorporation into polymers processed at moderate temperatures.
  • Low Volatility: This minimizes loss of the additive during processing and use, ensuring sustained performance and a safer working environment.
  • Good Compatibility: TBC disperses well in many polymer matrices, including polyolefins, PVC, ABS, and unsaturated polyesters, without significantly compromising mechanical properties.
  • Thermal Stability: It offers good resistance to thermal degradation during polymer processing.

Critical Applications in Polymers and Textiles:

TBC's effectiveness spans a wide array of applications:

  • Plastics: It is a preferred additive for enhancing the flame retardancy of polymers such as PE, PP, PVC, ABS, PS, EPS, and polycarbonates. These materials are used extensively in electronics, automotive interiors, construction components, and consumer goods, all of which often require compliance with strict fire safety standards like UL94 V-0.
  • Textiles: TBC imparts excellent flame retardancy to synthetic fibers and fabrics, making them safer for applications like upholstery, curtains, workwear, and technical textiles. Its durability and wash fastness are critical for textile applications.
  • Foams and Rubber: It is also utilized in polyurethane foams, XPS, EPS, and rubber conveyor belts to improve their fire resistance, contributing to safety in construction, furniture, and industrial settings.
