Uses

◆It can be used for natural rubber, butyl rubber, isoprene rubber, styrene-butadiene rubber, nitrile rubber and neoprene.

◆The activity is similar to that of the accelerator DPG. It has low activity at operating temperature and is safe to operate.

◆The critical temperature of vulcanization is 141℃, it is active at the vulcanization temperature, especially higher than the critical temperature, and the vulcanization flatness is good.

◆This product is an acid accelerator and an important active agent for thiazole and sulfenamide accelerators. It has the effect of super accelerator when used together with accelerator M.

◆Mainly used for thick-walled products, tread rubber, buffer layer, rubber roller covering rubber, etc.

◆When used as an accelerator, the dosage is generally 0.8-1.5

The dosage is 0.1-0.5 part when it is used as the second accelerator of the thiazole accelerator.
