- CPND is a highly efficient initiator used in the polymerization of low-density polyethylene (LDPE). It is suitable for both tubular and autoclave processes, with an optimal working temperature range between 130°C and 170°C.
- It also works as a high-activity initiator used in the suspension polymerization of vinyl chloride (PVC). It performs well at temperatures between 40°C and 65°C, making it an essential component in PVC production processes.
-
Packaging
CPND is usually packaged in 20 kg polyethylene drums. Customized packaging sizes are available upon request to meet specific customer requirements.
-
Validity
If CPND is stored and transported under the recommended conditions, it can maintain its quality for up to three months.
-
Safe Handling
Store in a cool, well-ventilated space with temperatures not exceeding -20°C.
Keep away from heat sources, open flames, and incompatible substances such as acids, flammable materials, and reducing agents.
Ensure storage areas are equipped with explosion-proof lighting, with switches located outside the room.
Handle with care to avoid damaging the packaging. Always wear appropriate personal protective equipment during handling.
Refer to the Material Safety Data Sheet (MSDS) for detailed safety information.
