دی(ترت-بوتیل‌پراکسی‌ایزوپروپیل)بنزن (BIPB)

BIPB (Di(tert-butylperoxyisopropyl)benzene, CAS 25155-25-3) is a high-efficiency, odorless crosslinking agent used for EPDM rubber, EVA, CPE, and silicone rubber crosslinking. It is the preferred alternative to DCP in applications requiring odor-free performance, such as wire and cable insulation, foam shoe soles, automotive rubber parts, and pipe production.

BIPB offers superior performance over DCP in odor-sensitive applications because its decomposition produces no acetophenone — the primary source of DCP's characteristic smell. BIPB also provides a higher crosslinking density and is available as a powder or masterbatch for easy handling in cable compounds and rubber processing.

The 10-hour half-life temperature of BIPB (CAS 25155-25-3) is 115°C, making it suitable for high-temperature processing typically above 150°C, such as in XLPE cable manufacturing and EPDM vulcanization.

LAAP (Lanzhou Auxiliary Agent Plant Co., Ltd.) is a leading BIPB manufacturer in China with over 35 years of export experience. We offer factory-direct pricing, free samples, REACH-certified documentation, and reliable export logistics to Russia, Central Asia, Southeast Asia and worldwide. Contact us at info@lzaux.com.

BIPB should be stored below 15°C in a cool, well-ventilated area, away from heat sources, open flames, and incompatible materials such as acids and reducing agents. When stored properly, BIPB retains its effectiveness for up to six months.

LAAP is a direct manufacturer of BIPB (CAS 25155-25-3), not a trading company or intermediary. As China's first organic peroxide producer since 1966, we offer factory-direct wholesale pricing with no middlemen. Minimum order starts from 25 kg (sample) with standard bulk orders from 200 kg. We export to 30+ countries including Russia, Germany, and Southeast Asia with full REACH/ISO documentation. Request a wholesale quote at info@lzaux.com.

The 1-hour half-life temperature of BIPB (Di(tert-butylperoxyisopropyl)benzene, CAS 25155-25-3) is 134°C. The 10-hour half-life is 115°C and the 0.1-hour (6-minute) half-life is 156°C. These parameters make BIPB ideal for high-temperature rubber vulcanization and XLPE cable crosslinking processes typically run at 160–200°C.

BIPB (CAS 25155-25-3) is also known as: Di(tert-butylperoxyisopropyl)benzene, 1,4-bis(tert-butylperoxyisopropyl)benzene, Bis(α,α-dimethylbenzyl) peroxide, Luperox DC (Arkema brand), Peroximon DC40, Trigonox DCBP (Nouryon brand), and BCP (used in some Chinese markets). All refer to the same molecule with CAS 25155-25-3.
