Applications:

1. This product is a commonly used polymerization initiator for ethylene polymerization, suitable for both autoclave and tubular reactor processes. It is also a polymerization initiator for acrylates and methacrylates, with an applicable temperature range of

80-150°C.

2. This product can be used as a polymerization initiator for styrene, with activity superior to BPO, and can also be used in combination with peroxides such as TBPB and TBEC. It is also an important initiator for ethylene-vinyl acetate (EVA) copolymers.

3. It serves as a high-temperature curing agent for unsaturated polyester resins, with a curing temperature of 120-160°C. It is the first choice for UP in hot-press compression molding processes (DMC, BMC), and can also be used with cobalt promoters at

60°C for air-drying coatings and filament winding processes.

Packaging and Transportation:

Our factory's standard packaging is 20 kg polyethylene packaging. Alternative packaging sizes can be supplied upon customer request; customers may specify requirements when placing orders.

Storage Precautions:

1. Store in a cool, well-ventilated area with warehouse temperature not exceeding 20°C.
2. Keep away from ignition sources and heat. Store separately from acids, reducing agents, flammable materials, combustible materials, and reducing agents.
3. Lighting and ventilation facilities in the storage area shall be explosion-proof, with switches installed outdoors.
4. Handle with care during transportation to prevent damage to packaging and containers. Impact and vibration are prohibited. Personal protective equipment shall be used during repackaging and handling operations.
5. Customers are advised to carefully read our factory's Material Safety Data Sheet (MSDS) before storage, transportation, and use of this product.

Product Shelf Life:
