(1) Polymerization initiator for vinyl chloride:

EHP is one of the most commonly used initiators of aqueous suspension polymerization of vinyl chloride. It is used in combination with CNP (isopropylphenyl peroxydecanoate), LPO (peroxydodecanoyl), etc. to improve the reaction activity and the polymerization temperature is 40-65°C.

(2) Ethylene polymerization initiator:

EHP is a low-temperature initiator of ethylene polymerization, commonly used in the tubular process, the use temperature of 130-160 ℃, can be used with a variety of initiators to form a compound initiator system.

Storage conditions:

Keep the package closed and in good ventilation, the maximum storage temperature is -15 ℃, avoid and reducing agents such as amines, acids, alkalis, heavy metal compounds (accelerators and metal soap), is strictly prohibited in the warehouse and access to the packaging.

Storage stability:

Preservation according to the conditions prompted by the manufacturer, the product in three months to ensure that the factory technical standards.

Fire extinguishing:

Small fires need to be extinguished with dry powder or carbon dioxide extinguishers, while spraying with a large amount of water to prevent re-ignition. Large fires need to be sprayed with a large amount of water at a safe distance, and notify the fire department.
