Applications:

1. Styrene Polymerization Initiator

LQ-DCP is a commonly used styrene polymerization initiator and also a flame retardant additive in the production of flame-retardant polystyrene.

2. Rubber Crosslinking Agent

LQ-DCP is one of the most important rubber crosslinking agents.

Storage Conditions: Keep the packaging tightly closed and in a well-ventilated environment. The maximum storage temperature is 30°C. Avoid contact with reducing agents such as amines, acids, alkalis, and heavy metal compounds (accelerators and metal soaps). Repackaging and use in the warehouse are strictly prohibited.

Storage Stability: When stored according to the manufacturer's instructions, the product will maintain its technical standards for three months.

Fire Extinguishing: Small fires should be extinguished with a dry powder or carbon dioxide fire extinguisher, and simultaneously sprayed with plenty of water to prevent reignition. Large fires should be sprayed with plenty of water from a safe distance.
