DTBP is a high-temperature organic peroxide commonly used as an initiator for high-pressure polymerization, particularly in rubber cross-linking and the polymerization of acrylic resins. Additionally, it serves as a versatile agent in polypropylene degradation, making it a key component in a variety of industrial processes that require precise and efficient polymer manipulation.
Widely used in the production of polymers, polymer cross-linking, and acrylic production. It is an effective initiator for low-density polyethylene (LDPE) production and is suitable for both tubular and autoclave processes. In practice, DTBP is often combined with other peroxides of varying activity levels to cover a broader range of polymerization temperatures, making it highly versatile in industrial settings.

Packaging
The standard packaging consists of 20 kg polyethylene drums. Customized packaging sizes can be arranged based on specific customer requirements.
-
Storage
Store DTBP in tightly sealed containers in a well-ventilated area with a maximum storage temperature of 40°C. Avoid contact with reducing agents such as amines, acids, bases, and heavy metal compounds (including accelerators and metallic soaps). DTBP should be protected from impact and friction, and it is not recommended to handle or repackage the product within the storage area.

Safe Handling
Strictly follow the recommended storage temperature guidelines to avoid fire hazards.
Keep the storage area free of open flames, heat sources, and static electricity. Ensure proper ventilation and avoid exposure to light.
When storing large quantities, use a separate storage facility. Prevent contact with reducing agents, rust, dust, heavy metals, acids, and bases.
Handle with care to avoid impact and friction.
