DPG(D)-80/75 Masterbatch | Secondary Accelerator for NR/BR Rubber

DPG(D)-80/75

Product Name: JXBHgran DPG(D)-80/75

Composition: 80% N, N'-diphenylguanidine, 20% Carriers and dispersing aids

Appearance: Gray-white particles

Density: About 1.06g/cm³

Filtration(μm): 140

Description

This DPG(D)-80/75 is used in natural rubber and synthetic rubber, but is not suitable for latex. It is 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 be activated by a thiazole catalyst in 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.
