Uses:

TAHP is a commonly used initiator 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 TAHP are mainly tert-butanol 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.

TAHP is also widely used as an initiator for the polymerization of styrene and styrene copolymers (e.g., SAN, ABS, etc.), acrylic and methacrylic acids, and vinyl chloride.

TAHP is a very important intermediate for organic synthesis.

Packaging:

The standard package is a polyethylene plastic drum with a net weight of 25 kg or 180 kg. IBC packages can also be used, but special attention should be paid to the SADT of 50°C and the critical temperature of 55°C when packaged in IBCs. Small packages are also

It can be packaged according to the specifications required by the user.

TAHP is a liquid organic peroxide of Class E, Goods Classification: 5.2, UN No. 3107, Packing Group II, Dangerous Goods.

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.

Storage conditions:

Keep the package closed and in a well-ventilated state, the maximum storage temperature of 35 ℃, 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.
