The chemical industry constantly seeks materials that can enhance the performance, durability, and processing of plastics and elastomers. Bis(tert-butyldioxyisopropyl)benzene Peroxide, or BIPB, has emerged as a highly effective crosslinking agent with a broad spectrum of chemical applications. NINGBO INNO PHARMCHEM CO.,LTD. is proud to offer high-grade BIPB, facilitating innovation across various manufacturing sectors. This article explores the extensive chemical applications of BIPB, focusing on its impact on plastics and elastomers.

What is BIPB and How Does it Work?

BIPB is an organic peroxide that functions as a crosslinking agent. Its unique molecular structure allows it to decompose at elevated temperatures, generating free radicals. These radicals initiate chemical reactions with polymer chains, creating strong covalent bonds between them. This process, known as crosslinking, transforms thermoplastic materials into thermoset materials or improves the properties of existing elastomers. The result is materials with significantly enhanced mechanical strength, thermal resistance, chemical stability, and reduced creep. The key advantage of BIPB, particularly when compared to agents like DCP, is its low odor profile during decomposition and use.

Key Chemical Applications of BIPB

BIPB finds extensive application in crosslinking a variety of polymers, each benefiting from its unique properties:

  • Ethylene-vinyl Acetate (EVA) Copolymers: BIPB is extensively used in the crosslinking of EVA. This is particularly crucial for the production of EVA foams, which are prevalent in footwear (like shoe IP and MD applications), sports equipment, and insulation materials. BIPB provides efficient crosslinking, leading to foams with excellent resilience, cushioning, and durability. The reduced odor is a significant plus for consumer-facing products. For manufacturers looking to buy BIPB for these applications, NINGBO INNO PHARMCHEM CO.,LTD. offers reliable sourcing.
  • Ethylene Propylene Diene Monomer (EPDM) Rubber: EPDM is renowned for its excellent weather resistance, ozone resistance, and thermal stability. BIPB acts as an efficient crosslinking agent for EPDM, further enhancing these properties. It improves tensile strength, elongation, and compression set resistance, making EPDM compounds suitable for automotive hoses, seals, O-rings, and roofing membranes.
  • Silicone Rubber: Silicone rubber is prized for its wide operating temperature range and flexibility. BIPB crosslinking helps to maximize these inherent advantages, leading to silicone products with improved mechanical integrity and heat resistance. This is vital for applications in electronics, healthcare, and aerospace.
  • Other Elastomers and Plastics: BIPB's versatility extends to a range of other materials. It is effective in crosslinking chlorinated polyethylene (CPE), hydrogenated butadiene rubber (HNBR), nitrile rubber (NBR), fluororubbers, and even thermoplastic elastomers (TPEs) and polyurethane rubbers (XPU). Its application in challenging processes like supercritical foaming underscores its efficacy.

Advantages in Specific Processes

BIPB is particularly recommended for processes requiring high-performance outcomes:

  • Foaming Applications: In EVA foaming, BIPB ensures consistent cell structure and good expansion, vital for achieving desired density and mechanical properties.
  • High-Temperature Vulcanization: For applications requiring components to withstand elevated temperatures, BIPB's thermal stability and efficient crosslinking contribute to superior long-term performance and reduced material degradation.
  • Odor-Sensitive Products: When the final product needs to be odorless, such as in automotive interiors or children's toys made from EVA foam, BIPB is the preferred crosslinking agent.
