Small packages can also be packed according to the specifications required by users. Safety Precautions: (1) Keep away from fire, open flame and heat source. (2) Avoid contact with reducing agents (e.g., amines), acids, alkalis, and heavy metal compounds (e.g., accelerators, metal soaps, etc.) (3) Refer to the Safety Data Sheet (MSDS) for this product. Uses: (1) Polymerization initiator for vinyl chloride: EHPC is the most commonly used initiator for the aqueous phase suspension polymerization of vinyl chloride, which can be used in combination with CUPN (isopropylphenyl peroxyneodecanoate), LPO (lauroyl peroxide), etc., to improve the reaction activity, and the polymerization temperature is 40-65℃. (2) Vinyl polymerization initiator: EHPC is a low-temperature initiator for ethylene polymerization, commonly used in tubular process, the use of the temperature of 130-160 ℃, can be used with a variety of initiators to form a complex initiator system. Storage conditions: Keep the package closed and under good ventilation, the maximum storage temperature is -15℃, avoid and reducing agents such as amines, acids, alkalis, heavy metal compounds (accelerators and metal soaps), strictly prohibited in the warehouse to split and take. Storage stability: According to the manufacturer's prompt conditions for preservation, 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 and also sprayed with large quantities of water to prevent re-ignition. Large fires need to be sprayed with large quantities of water from a safe distance away.
