Applications
| Application | Description |
|---|---|
| Polymerization Initiator | Common initiator for ethylene polymerization, suitable for batch and tubular processes. Also suitable for acrylate and methacrylate polymerization, with a temperature range of 80-150°C. |
| Styrene Polymerization | Superior activity compared to BPO for styrene polymerization; can be used in combination with other peroxides like TBPB and TBEC. |
| Vinyl Acetate (EVA) Copolymer | Important initiator for EVA copolymerization. |
| Curing Agent for Unsaturated Polyester | High-temperature curing agent for unsaturated polyesters, with curing temperatures of 120-160°C. Primarily used in UP hot press molding (DMC, BMC) processes, also used with cobalt-based accelerators for air-dry coatings and filament winding processes at 60°C. |
Packaging and Transport
