1. Free radical initiator: LP is a common free radical initiator. It can be decomposed to produce free radicals and participate in reactions such as free radical polymerization and free radical substitution. It is often used in polymerization reactions under high temperature conditions, such as the synthesis of synthetic resins and plastics.

2. Rubber processing: chemical dilauryl peroxide can be used as a crosslinking agent for rubber. It can react with the double bond in rubber, trigger a cross-linking reaction, and increase the hardness, strength and wear resistance of rubber.

3. Cosmetics and beauty products: Dilauryl peroxide is commonly used in cosmetics and beauty products. Due to its oxidizing properties, it can be used as a bleach, whitening agent, fading agent, etc., for removing pigment or acne marks.

4. Pharmaceutical field: China dilauryl peroxide is also used in the pharmaceutical field. It can be used as a pharmaceutical intermediate to synthesize lead compounds for some drugs. In addition, dilauryl peroxide can also be used to treat herpes, acne and other diseases.
