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

Purpose:

1. Ethylene polymerization initiator

TMHP is the most commonly used LDPE tubular or kettle polymerization initiator. In order to obtain a wider polymerization temperature range, it is often used in conjunction with other initiators, with a polymerization temperature of 150-190 ℃.

2. Vinyl chloride polymerization initiator

TMHP is also an initiator for the aqueous suspension polymerization of vinyl chloride, with an initiation temperature of 50-70 ℃.

Storage conditions:

Keep the packaging sealed and in a well ventilated state, with a maximum storage temperature of 0 ℃. 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.
