NINGBO INNO PHARMCHEM CO.,LTD. provides cutting-edge chemical solutions for industries requiring robust material performance. Among these, Bis(tert-butylperoxy isopropyl)benzene (BIBP) is a standout organic peroxide, particularly valued for its role as a crosslinking agent in challenging rubber formulations. Its efficacy is highly demonstrated in polymers such as Ethylene Propylene Diene Monomer (EPDM) rubber, silicone rubber, nitrile rubber, and fluororubber.

EPDM rubber is known for its excellent resistance to weathering, ozone, and heat, making it ideal for automotive parts, roofing membranes, and electrical insulation. The addition of BIBP as a crosslinking agent further enhances these properties. It improves the thermal stability, compression set resistance, and overall mechanical integrity of EPDM compounds. While BIBP offers advantages like lower odor, users should be mindful of compatibility; the decomposition products of BIBP can sometimes exhibit poor compatibility with EPDM, potentially leading to blooming (migration to the surface). To mitigate this, NINGBO INNO PHARMCHEM CO.,LTD. recommends using BIBP in conjunction with bridging aids like TMPTMA or TAIC, and limiting its dosage in EPDM to around 3%.

Silicone rubber and fluororubber are also prime candidates for BIBP crosslinking. These high-performance elastomers are used in extreme temperature environments and demanding sealing applications. BIBP contributes to achieving dense, stable crosslinked networks in these materials, ensuring their continued performance under harsh conditions. For instance, BIBP is particularly suitable for silicone rubber molding vulcanization chambers, contributing to products like rubber sheathed cables for air conditioners.

The advantage of using BIBP over traditional peroxides in these specialty rubbers lies in its efficiency and improved processing characteristics. While achieving similar crosslinking effectiveness, BIBP often requires a lower dosage, and its minimal odor during processing and in the finished product is a significant market advantage. NINGBO INNO PHARMCHEM CO.,LTD. is committed to supporting rubber manufacturers with reliable, high-quality crosslinking agents that meet the industry's evolving demands for performance and consumer satisfaction.
