Applications:
1. This product is a commonly used polymerization initiator for ethylene polymerization and is suitable for both batch and continuous processes. It also serves as a polymerization initiator for acrylates and methacrylates, with an applicable temperature range of
80–150°C.
2. This product can be used to initiate styrene polymerization; its activity is superior to that of BPO, and it can also be used in combination with peroxides such as TBPB and TBEC. It is also a key
initiator for ethylene vinyl acetate (EVA) copolymers.
3. It serves as a high-temperature curing agent for unsaturated polyesters, with a curing temperature range of 120–160°C. It is the preferred choice for the curing of unsaturated polyesters (UP) in hot-press molding processes (DMC, BMC). It can also be used in conjunction with cobalt-based accelerators at
60°C for air-drying paints and filament winding processes.
Packaging and Transportation:
Our standard packaging is 20-kilogram polyethylene bags. We can also supply packaging sizes according to customer requirements; customers may specify these when placing an order.
Storage Precautions:
1. Store in a cool, well-ventilated area at a temperature not exceeding 20°C.
2. Keep away from sources of ignition and heat. Store separately from acids, reducing agents, flammable substances, combustible materials, and other reducing agents.
3. Lighting and ventilation facilities in the storage area must be explosion-proof, and switches should be located outdoors.
4. Handle with care to prevent damage to packaging and containers. Avoid impact and vibration. Wear appropriate personal protective equipment during repackaging and handling operations.
5. Customers are requested to carefully read our factory’s “Material Safety Data Sheet (MSDS)” when storing, transporting, and using this product.
Product Shelf Life:
When stored and transported in strict accordance with the manufacturer’s instructions, product quality is guaranteed for three months.
Fire Protection:
1. This product may decompose violently when exposed to heat, causing a fierce fire. Small fires involving a small amount of the product should be extinguished immediately using a foam or dry powder fire extinguisher.
2. In the event of a large fire, evacuate immediately to a safe distance and use a water hose to suppress the flames; notify the fire department for further handling.
