packing:

The standard packaging is a polyethylene plastic drum with a net weight of 25 kilograms or 180 kilograms, which can also be packaged in IBC or transported by tank car. However, it is important to pay special attention to the SADT of 55 ℃ and the critical temperature of 50 ℃ when packaged in IBC or tank car. Small packaging can also be packaged according to user specifications.

LQ-BCHPC is a Class F solid organic peroxide, with a cargo classification of 5.2 and a United Nations number of 3109. It is a Class II dangerous goods packaging

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:

LQ-TBHP is the most commonly used initiator for free radical reaction. It is characterized by good thermal stability, safe use, easy control, no significant change in its activity within three months at temperatures below 50 ℃, and no need for costly frozen storage. It can be used in lotion polymerization, aqueous polymerization, curing, grafting polymerization and other fields. Its performance is better than that of persulfate, cumene hydroperoxide and benzoyl peroxide in many aspects. The decomposition products of TBHP are mainly tert butanol , which are non corrosive and do not require high equipment requirements. Most other initiators will form acidic byproducts.

LQ-TBHP is also widely used as a polymerization initiator for styrene, acrylic acid, and methacrylic acid.

LQ-TBHP is a vulcanizing agent for natural rubber. It can be used to improve the cetane number of diesel oil. At the same time, it is also a very important organic synthesis intermediate, with special selectivity and high yield for epoxidation, and is a very important oxidant.

Storage conditions:

Keep the packaging sealed and in a well ventilated state, with a maximum storage temperature of 40 ℃. 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 six 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.
