Application:
1.Ethylene Polymerization Initiator
TMHP is one of the most commonly used initiators for the polymerization of LDPE via both tubular and autoclave processes. To achieve a broader polymerization temperature range, it is often used in combination with other initiators. The typical polymerization temperature is 150–190 °C.
2.Vinyl Chloride Polymerization Initiator
TMHP is also used as an initiator for vinyl chloride polymerization via the aqueous suspension method, with an initiation temperature of 50–70 °C.
Package and Storage：
Our standard packaging is 20 kg polyethylene containers.
Store in a cool, ventilated area with warehouse temperatures not exceeding 0°C.
Keep away from fire and heat sources. It should be stored separately from acids, flammables, combustibles, and reducing agents.
