Applications:
This product is an initiator used in the aqueous suspension or bulk polymerization of vinyl chloride, with an initiation temperature of 45°C–65°C. It is characterized by a low level of “fish-eye” defects in the polymer product and a narrow resin particle size distribution. It
can be used in combination with various other initiators, such as LPO, CUPD, and TMPD.
This product can also be used as an initiator for the polymerization of acrylic acid and methacrylic acid.
Packaging and Shipping:
Our standard packaging consists of 20-kilogram corrugated cardboard boxes, each containing four plastic bags with a net weight of 5 kilograms per bag. 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 20°C.
2. Keep away from sources of ignition and heat. Store separately from acids, reducing agents, flammable and combustible materials, and other 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:
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 extinguish the flames; notify the fire department for further handling.
