Description

This DPG Rubber Chemical Accelerator is used in natural rubber and synthetic rubber, while not suitable for latex. It mainly used in the manufacture of tires, shoes and other rubber industrial products.
Function

JXBHgran DPG-80 provides a very long time of scorch and relatively slow vulcanization, which can cause slight discoloration and can not be used for light-colored products unless added as an activator. JXBHgran DPG-80 can activated thiazole catalyst. In the IIR and EPDM.
Dosage

Main accelerator: 1.0-2.0 phr with 2.5-3.5 phr of sulfur.

Second accelerator: 0.1-0.25 phr with 0.75-1.0 phr thiazoles and 2.5 phr of sulfur.
Application

It can be used for a variety of rubber industrial products.
