DCP is a Class F solid organic peroxide. Cargo classification: 5.2; UN Number: 3110; Class 2 dangerous goods packaging.
Safety Precautions:
(1) Keep away from sources of ignition, open flames, and heat sources.
(2) Avoid contact with reducing agents (such as amines), acids, alkalis, and heavy metal compounds (such as accelerators, metal soaps, etc.).
(3) Please refer to the Material Safety Data Sheet (MSDS) for this product.
Applications:
1. Styrene Polymerization Initiator
DCP is a commonly used styrene polymerization initiator and also serves as a flame retardant additive in the production of flame-retardant polystyrene.
2. Rubber Crosslinking Agent
DCP is one of the most important rubber crosslinking agents.
Storage Conditions:
Keep the packaging tightly sealed and store in a well-ventilated area at a maximum temperature of 30°C. Avoid contact with reducing agents such as amines, acids, alkalis, and heavy metal compounds (accelerators and metal soaps). Repackaging and handling within the warehouse are strictly prohibited.
Storage Stability:
When stored under the conditions specified by the manufacturer, the product is guaranteed to meet factory technical standards for three months.
Fire Extinguishing:
For small fires, use dry powder or carbon dioxide fire extinguishers, while simultaneously spraying with large amounts of water to prevent reignition. For large fires, spray with large amounts of water from a safe distance.
