DCP is a Class F solid organic peroxide, cargo classification: 5.2, UN number: 3110, packaging for Class II dangerous goods.

Safety precautions:

(1) Keep away from sparks, open flames, and heat sources.

(2) Avoid contact with reducing agents (such as amines), acids, bases, and heavy metal compounds (such as accelerators, metal soaps, etc.)

(3) Please refer to the Safety Data Sheet (MSDS) of this product.

Purpose:

1．Styrene polymerization initiator

DCP is a commonly used styrene polymerization initiator and also a flame retardant additive for the production of flame retardant polystyrene.

2．Rubber crosslinking agent

DCP is the most important rubber crosslinking agent.

Storage conditions:

Keep the packaging sealed and in a well ventilated state, with a maximum storage temperature of 30 ℃. Avoid mixing with reducing agents such as amines, acids, alkalis, and heavy metal compounds (accelerators and metal soaps). It is strictly prohibited to pack or use in the warehouse.

Storage stability:

Store according to the manufacturer's instructions, and the product can meet the factory technical standards within three months.

Fire extinguishing:

Small fires need to be extinguished with dry powder or carbon dioxide fire extinguishers, and a large amount of water should be sprayed to prevent reignition. A large fire requires spraying a large amount of water from a safe distance.
