Applications
  • Used as an initiator in the polymerization of styrene and its copolymers, with a temperature range of 100-130°C. In bulk polymerization, it helps to increase the reaction rate. In water-phase suspension polymerization, it reduces residual styrene monomers during the final stages.
  • Suitable for polymerization processes involving acrylates and methacrylates, with a working temperature range between 100-170°C, making it highly versatile across various applications.
  • TBEC is a preferred curing agent for hot-press molding processes like SMC, BMC, and ZMC, with temperatures between 120-170°C. It ensures good product durability while being environmentally safe.
  • Packaging

    Typically supplied in 25 kg PE drums for safe storage and handling, but other packaging options can be arranged to meet specific customer requirements.

  • Storage

    Store in an area with proper ventilation, tightly sealed to prevent contamination. The maximum storage temperature should not exceed 25°C, and avoid exposure to incompatible chemicals such as acids, alkalis, heavy metal compounds (accelerators and metallic soaps). Repacking or transferring the product in storage areas is not recommended.

  • Storage Stability

    If stored correctly, this chemical compound retains its quality for up to three months under the conditions specified by the manufacturer.

  • Safe Handling

    Keep the product away from open flames, heat sources, and ignition points to ensure safety during handling and storage.
    Avoid contact with incompatible chemicals like reducing agents (amines), acids, bases, and heavy metal compounds (such as accelerators, metallic soaps).
    Refer to the Material Safety Data Sheet (MSDS) for detailed safety guidelines and handling instructions.
