Accelerators for various types of chloroprene rubber, chlorosulfonated polyethylene rubber, chloroether rubber, and acrylic rubber. Suitable for metal oxide vulcanization, especially magnesium oxide and zinc oxide as vulcanizing agents have better effect. It is safe to operate and not easy to burn. Under normal vulcanization temperature, the vulcanization speed is faster. With the increase of the dosage, the vulcanization speed can still be increased, but the scorch resistance performance is reduced. The combination of the accelerator DM can improve the scorch resistance performance. High, small compression deformation, good elasticity and heat resistance. It is easy to disperse in rubber compound, does not pollute and does not change color. The amount in general products is 0.25-1.5 parts.
package：Polypropylene woven bag lined with polyethylene film, 25kg per bag.
