Question 1

What is BIPB (CAS 25155-25-3) used for?

Accepted Answer

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.

Question 2

How does BIPB differ from DCP (dicumyl peroxide)?

Accepted Answer

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.

Question 3

What is the 10-hour half-life temperature of BIPB?

Accepted Answer

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.

Question 4

Where can I buy BIPB 25155-25-3 from a factory in China?

Accepted Answer

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.

Question 5

What is the storage temperature for BIPB?

Accepted Answer

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.

Question 6

Is LAAP a BIPB 25155-25-3 wholesaler or manufacturer?

Accepted Answer

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.

Question 7

What is the 1-hour half-life temperature of BIPB?

Accepted Answer

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.

Question 8

What are the alternative names and synonyms for BIPB CAS 25155-25-3?

Accepted Answer

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.
