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.
Packing
25 kg in carton box with polyethylene bag liner.
Storage
The storage period of one year under cool and dry conditions.
