What is Dilauroyl peroxide?

Dilauroyl peroxide, also known as lauroyl peroxide, initiator B, white powder with pleasant odor.

Dilauroyl peroxide is easily soluble in acetone, chloroform and other organic solvents and oils, but insoluble in water.

Dilauroyl peroxide is stable at room temperature and easily exploded when heated.

Mainly used as a high-efficiency initiator for polyvinyl chloride and high-pressure polyethylene.

It is also used as a bleaching agent in the food industry and oil production.

It can also be used as polyester curing agent, rubber cross-linking agent, foaming agent, bleaching agent, drying agent, etc.


1. Polymerization of vinyl chloride:
Dilauroyl peroxide is widely used in aqueous suspension polymerization and bulk polymerization. The temperature range of the polymerization is 60-75℃. In many cases, LPO and other highly active peroxides are combined to make LPO It can be increased with, for example, peroxide dicarbonates (di-4-tert-butylcyclohexane peroxide dicarbonate), or peroxy esters (1, 1, 3, 3-tetramethylbutyl peroxide neocapric acid-1, 1, 3) Reactivity.

2. Polymerization of ethylene:
Dilauroyl peroxide is used in the polymerization of high pressure polyethylene. Due to its poor solubility, it is replaced by isononyl peroxide in many cases, but the biggest advantage of LPO is that it can be used at room temperature Save.

3. Polymerization of acrylate and methacrylate:
Dilauroyl peroxide can also be used for the polymerization of acrylate, polymerization reaction temperature of 60-90℃, often used to replace the more toxic azo diisobutyronitrile, etc.

4. ABS resin polymerization initiator:
Dilauroyl peroxide is also an important initiator of ABS polymerization reaction. It is used in combination with 1, 1-ditert-butyl peroxide-3, 3, 5-trimethylcyclohexane (LQ-CH335), and has a good initiation The effect.
