As of 2023, China's measurable TBPB (tert-Butyl peroxybenzoate) production capacity is approximately 30,000 tons, with main factories located in Jiangsu, Shandong, and Jiangxi. The world's largest supplier of TBPB (tert-Butyl peroxybenzoate) is the prominent Chinasun Specialty Products Co., Ltd. Here are several essential points to know about TBPB:
1. TBPB (tert-Butyl peroxybenzoate) is one of the few pure peroxides, with a purity close to 100%. According to Chinese industry standards, Grade A TBPB must have a purity of no less than 98.5%.
2. The active oxygen content in TBPB (tert-Butyl peroxybenzoate) is around 8.25%. When TBPB is used in formulations, its oxygen content decreases correspondingly after dilution.
3. The color stability of TBPB is a critical quality indicator, particularly in its applications in the acrylic acid industry which demands high color standards. Over time, TBPB may experience some yellowing. High-quality TBPB (tert-Butyl peroxybenzoate), such as Nouryon's TRIGONOX C, exhibits better resistance to yellowing. For color-sensitive applications, it is recommended to store TBPB at temperatures between 10-15°C.
4. TBPB (tert-Butyl peroxybenzoate) tends to crystallize in cold weather. Before use, it should be heated in a water bath; direct heating over fire is strongly discouraged.
5. TBPB (tert-Butyl peroxybenzoate) is used as a mid-temperature initiator for polymerization reactions (like polystyrene, polyethylene, and acrylic polymers), a curing agent for unsaturated polyester, and a vulcanizing agent for silicone rubber. The typical usage ratio for initiators to curing agents to vulcanizing agents is approximately 6:3:1, with the largest consumption typically found in EPS factories.
These points underline the critical attributes and handling instructions for TBPB, essential for maintaining its efficacy in various industrial applications.
