Bis(tert-butyldioxyisopropyl)benzene (BIPB) is a sophisticated organic peroxide that serves as a highly effective crosslinking agent across a spectrum of polymer systems. Understanding its chemical properties is key to leveraging its full potential in applications demanding enhanced material performance, durability, and processing efficiency. NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing detailed technical insights into our BIPB product to empower our clients.

At the core of BIPB's efficacy is its high active oxygen content, typically around 9.08%. This characteristic dictates its potency as a free radical generator upon thermal decomposition. When heated, BIPB breaks down into reactive free radicals that initiate the formation of covalent bonds between polymer chains, thereby creating a crosslinked network. This process significantly improves the polymer's mechanical properties, thermal stability, and chemical resistance.

The thermal decomposition profile of BIPB is a crucial differentiator. Unlike dicumyl peroxide (DCP), whose decomposition can yield odor-causing byproducts, BIPB's primary decomposition products are generally less odorous gases and volatile liquids such as methane, acetone, and tert-butanol. This characteristic is vital for applications where odor is a critical concern, ensuring a better user experience and a more pleasant manufacturing environment. The 10-hour half-life temperature for BIPB is typically around 114°C, indicating its suitability for processing temperatures commonly encountered in rubber and plastics manufacturing, while its SADT (Self-Accelerating Decomposition Temperature) of 80°C highlights the need for careful storage and handling.

The technical advantages of BIPB translate directly into tangible benefits for various polymers. In EPDM rubber, it improves tensile strength and compression set resistance. For EVA copolymers, it enhances resilience and impact strength, particularly in foam applications. Silicone rubbers benefit from BIPB's ability to improve thermal aging resistance and flexibility. Furthermore, BIPB's compatibility extends to materials like chlorinated polyethylene (CPE), nitrile rubber (NBR), and polyurethane (XPU) elastomers, making it a versatile solution for diverse industrial needs. NINGBO INNO PHARMCHEM CO.,LTD. ensures our BIPB is produced to exacting specifications, guaranteeing its consistent performance and technical reliability for all your crosslinking requirements.
