Safety Precautions:

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

(2) Avoid exposure to reducing agents (e.g., amines), acids, alkalis, and heavy metal compounds (e.g., accelerants, metal soaps, etc.)

(3) Refer to the Safety Data Sheet (MSDS) for this product.

Uses:

TBHP is one of the most commonly used initiators for free radical reactions, characterized by good thermal stability, safe to use, easy to control, at 50°C

The activity does not change significantly within three months and does not require expensive refrigerated storage. It can be used in the fields of emulsion polymerization, aqueous phase polymerization, curing and adhesive polymerization, etc., and has the following properties in many aspects

It is better than peroxodisulfate, isopropylbenzene peroxide and benzoyl peroxide.The decomposition products of TBHP are mainly tert-butyl alcohol and a small amount of acetone, etc., which are non-corrosive and do not require high equipment. And its

Most of its initiators form acidic byproducts.

TBHP is also widely used as an initiator for the polymerization of styrene, acrylic acid and methacrylic acid.

TBHP is a vulcanizing agent for natural rubber. It can be used to improve the cetane number of diesel fuel. It is also a very important organic synthesis intermediate, which has special selectivity for epoxidation and

High yield and a very important oxidizing agent.

Storage conditions:

Keep the package closed and in a well-ventilated state, the maximum storage temperature of 40 ℃, to avoid and reducing agents such as amines, acids, alkalis, heavy metal compounds (accelerators and metal soaps), is strictly prohibited in the warehouse

Room dispensing and pickup.

Storage stability:

Stored in accordance with the conditions prompted by the manufacturer, the product can be guaranteed to meet factory technical standards within six months.

Fire Fighting:

Small fires need to be extinguished with dry powder or carbon dioxide extinguishers and sprayed with large amounts of water to prevent re-ignition. Large fires need to be sprayed with large quantities of water from a safe distance away.
