Recent explosions involving organic peroxides, particularly in the PVC industry, have sparked significant concerns. These incidents highlight the dangers associated with peroxide production and storage, emphasizing the need for strict temperature control, enhanced safety protocols, and careful handling in the industry.
On August 2, 2024, a significant explosion in a TBPB container at Ningbo Port in China underscored the grave risks associated with handling organic peroxides. This incident validates Heinrich's Law, which suggests that major accidents are preceded by numerous smaller incidents and safety oversights. Given the extreme temperatures affecting global shipping conditions, there is an urgent need to reevaluate and improve safety protocols and handling standards for hazardous materials. The explosion has prompted stricter regulatory measures at major ports and heightened caution among shipping companies, with an emphasis on safety and quality control to prevent future catastrophes.
Tertiary Butylhydroperoxide (TBHP) boasts a production capacity led by major manufacturers like Nouryon and Qiangsheng Functional Chemistry Ltd., with LyondellBasell as a key global supplier. Despite a temporary shortage in 2022 due to extreme weather, TBHP remains essential in polymerization processes and other organic peroxide productions. It is unique for its compatibility with water and high active oxygen content, which underscores its role in various industrial applications. Commonly packaged in large containers, TBHP serves as an oxidant, initiator, and intermediate across multiple sectors.
The DCBP Production Capacity in China stands at approximately 250 tons, with major contributions from Nouryon and Qiangsheng. Due to its decomposition risks, DCBP Cold Chain Transportation is crucial, particularly during warmer months. Lastly, the DCBP Grades and Standards are vital for its use across industrial, food, and pharmaceutical sectors, ensuring compliance with rigorous safety and quality regulations.

Lauroyl Peroxide (LPO) is a niche chemical with Lauroyl Peroxide production capacity of 100 tons in China, exclusively manufactured by Strong Functional Chemicals Co., Ltd. Known for its high level of Lauroyl Peroxide safety with a Self-Accelerating Decomposition Temperature (SADT) of 50°C, LPO is primarily utilized in various Lauroyl Peroxide applications, including the (co)polymerization of styrene and vinyl chloride. The market is mainly supplied by imported products from Nouryon and Arkema, leading to occasional shortages in China.
DHBP Peroxide (2,5-Dimethyl-2,5-di(tert-butylperoxy)hexane) is a key organic peroxide with a production capacity of around 2,000 tons in China as of 2023. Primarily produced by Nouryon Chemicals (Ningbo) Co., Ltd. and Jiangsu QiangSheng Functional Chemicals Co., Ltd., it is essential for various industrial applications. DHBP Peroxide, dependent on raw materials from Japan's Sumitomo Chemical, saw a price surge in 2020 due to increased demand for melt-blown fabric degradation. It is known for its safety, purity, and diverse applications in polymer cross-linking and degradation, with specific storage and packaging requirements.
In recent years, with the continuous increase in demand for high polymers and polypropylene materials, China's DTBP (Di-tert-butyl peroxide) market has shown significant growth. In 2023, China's DTBP production capacity was approximately 15,000 tons, with the capacities of major factories being similar. However, as one of the organic peroxides with relatively simple preparation processes, DTBP's production capacity is highly flexible. Factories can adjust production capacity at any time to meet market changes.
Benzoyl Peroxide (BPO) is used in pharmaceutical, food, and industrial applications. It must be stored with diluents or stabilizers for safety and is sensitive to proper handling and packaging. Ensuring purchase from certified manufacturers is crucial to avoid the risks associated with substandard products.
For TBPB (CAS-No 614-45-9), we recommend packaging no heavier than 25 kg using light-blocking high-density polyethylene. Containers may optionally include breathable Gore-Tex lids. Ensure packaging passes drop tests and stacks no more than three layers on pallets, adhering to Level II standards or higher. Key temperature guidelines include a flash point of 96°C, suggesting low vapor flash ignition risk, and an SADT of 63°C, making refrigeration generally unnecessary during summer sea transport. Storage should ideally be at 10-30°C to minimize quality degradation and maximize safety.
This month, our book club dove deep into the transformative world of "Nonviolent Communication" by Marshall Rosenberg, a guide that not only challenges us to rethink our speech but also the quality of our connections. During our engaging session, members shared personal stories and insights, highlighting how the principles from the book resonated with their experiences and struggles in communication. We explored how "Nonviolent Communication" encourages empathy and understanding in place of judgment and criticism, fostering deeper bonds in our personal and professional lives.
