Tert-Butyl peroxybenzoate (TBPB) a chemical compound from the group of peresters. It is often used as a radical initiator in polymerization reactions, such as the production of LDPE from ethylene, and for crosslinking, such as for unsaturated polyester resins.
As peroxo compound, TBPB contains about 8.16 wt% of active oxygen and has a self accelerating decomposition temperature (SADT) of about 60 °C. The SADT is the lowest temperature at which self-accelerating decomposition in the transport packaging can occur within a week, and which should not be exceeded while storage or transportation.[2] TBPB should therefore be stored between minimum 10 °C (below solidification) and maximum 50 °C. Dilution with a high-boiling solvent increases the SADT. The half-life of TBPB, in which 50% of the peroxy ester is decomposed, is 10 hours at 104 °C, one hour at 124 °C and one minute at 165 °C. Amines, metal ions, strong acids and bases, as well as strong reducing and oxidizing agents accelerate the decomposition of TBPB even in low concentrations.[ However, TBPB is one of the safest peresters or organic peroxides in handling. The main decomposition products of tert-butyl peroxybenzoate are carbon dioxide, acetone, methane, tert-butanol, benzoic acid and benzene.

Xiang pump developed with independent intellectual property rights of the oil pump test bed
In response to the stringent testing requirements for Cummins B series synthetic oil pump products, Hunan Oil Pump Co., Ltd. collaborated with a university to develop a semi-automatic machine performance test bench featuring advanced domestic-level technology and independent intellectual property rights. Within just three months, the company successfully built and deployed two such systems, achieving excellent results. When representatives from Cummins in the U.S. visited the facility, they were impressed by the test equipment, which fully met the technical specifications set by the U.S. and accurately fulfilled the product testing requirements. The system received high praise and endorsement from Mr. Ignacio, Vice President of Cummins.
This advanced test equipment is fully automated, capable of handling product loading and unloading, screen display, automatic hydraulic clamping, testing, data recording, and storage. It can measure various performance parameters, including low, medium, and high-speed operations, pressure levels, flow rates, torque, oil temperature, and test duration—all displayed on the screen. Qualified products are automatically labeled with a serial number and test date. In case of any technical parameter failure, the system triggers both an audio and visual alarm, while the corresponding unqualified items are marked with a red warning on the screen. This ensures real-time monitoring and quality control, significantly improving efficiency and accuracy in the testing process.
