Nouryon Brand DirectorAn Overview of DCBP (Dichlorobenzoyl Peroxide) in China: Production Capacity and Market Trends
DCBP, chemically known as dichlorobenzoyl peroxide and commonly referred to as Double Two Four is identified with CAS number 133-14-2. As of 2023, China's measurable production capacity for DCBP stands at approximately 250 tons. Dominating the Chinese market, Nouryon and Qiangsheng collectively hold over 90% of the market share, with companies like Arkema, Unitherm, AKAP, and Pergan (Bokjin) also maintaining product lines for DCBP.
Primarily used as a vulcanizing agent in extruded silicone rubber, DCBP is crucial for the industry. Here are several key points to consider regarding DCBP:
1. DCBP has a Self-Accelerating Decomposition Temperature (SADT) of 60°C. Due to the instability of its carriers, cold chain transportation is recommended during the summer months to ensure safety.
2. DCBP typically appears in a paste form with a concentration of 50%.
3. The theoretical active oxygen content of DCBP is 4.2%.
4. Common carriers for DCBP include DIBP and silicone oil. Factories with specific requirements for halogens and plasticizers might opt for halogen-free or plasticizer-free DCBP.
5. DCBP is available in various grades including food, pharmaceutical, and industrial. For instance, Nouryon's Perkadox PD-50S-Ps is a pharmaceutical grade DCBP that is REACH certified.
6. Standard packaging for DCBP is in 20kg PE drums to ensure product integrity and ease of transport.
7. In earlier years, several underground factories in Guangdong and Shandong provinces produced DCBP. However, due to its limited applications and decreasing profit margins, many have ceased production. As the silicone industry evolves, the demand for higher quality DCBP is also increasing, reflecting the industry's heightened standards.
