Rubber Accelerator D-80 (DPG-80) provides a very long time of scorch and relatively slow vulcanization, which can cause slight discoloration and it can be used for light colored products unless added as an activator. it can activated thiazole catalyst. In the IIR and EPDM, DPG-80'S effect is not obvious.
It can be used for a variety of rubber industrial products. The major usages is for tires, natural rubber, synthetic rubber, other rubber industrial products, not suitable for latex, etc.
