Usage: This type of accelerator has low promoting effect and poor resistance to burning, so it is rarely used for diene rubber. However, in special circumstances, such as when sulfur such as thiuram sulfide is used for sulfurization, it has the effect of an active agent. accelerators have unique effectiveness in the vulcanization of chloroprene rubber, and can produce chloroprene vulcanized rubber with good properties such as tensile strength, hardness, and compression set. Compared with NA-22, this product has faster burning and sulfurization, but better flatness. Easy to disperse and does not spray frost. When used in large quantities, it can be subjected to high-temperature and high-speed vulcanization, especially suitable for continuous vulcanization of extruded products. This product is also an accelerator for butyl rubber and a vulcanization activator for EPDM rubber. It has antioxidant properties for natural rubber, chloroprene rubber, nitrile rubber, and styrene butadiene rubber. Generally used for manufacturing industrial products, special wires, sponge products, etc.
Packaging and storage: Plastic woven bags, paper plastic composite bags, kraft paper bags, etc. lined with polyethylene film packaging, each bag weighing 25kg, should be stored in a cool, dry, and well ventilated place. Packaged products should be protected from direct sunlight. Valid for 1 year.
