Applications:
1. An excellent low-temperature initiator for high-density polyethylene (LDPE), commonly used in the tubular process. It can be combined with initiators such as TBPV (tert-butyl pivalate peroxide), TBPEH (tert-butyl 2-ethylhexanoate peroxide
butyl ester), and initiator TBPB (tert-butyl perbenzoate) to form a composite initiator system, which yields better polymerization results.
2. A high-temperature curing agent for unsaturated polyesters.
3. Can be used as a polymerization initiator for vinyl chloride, styrene, or styrene copolymers, as well as for methacrylates and vinyl acetate.
Packaging and Shipping:
Our standard packaging is 20 kg polyethylene bags. We can also supply packaging sizes according to customer requirements; customers may specify their needs when placing an order.
Storage Precautions:
1. Store in a cool, well-ventilated area at a temperature not exceeding -10°C.
2. Keep away from sources of ignition and heat. Store separately from acids, flammable and combustible materials, and reducing agents.
3. Lighting and ventilation facilities in the storage area must be explosion-proof, with switches 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:
