Product Appearance
Used as a secondary accelerator with thiazoles and sulphenamides in NR and SBR compounds. Exhibits better storage stability compared to thiuram and dithiocarbamates but is not so active. Willing DPG can be used in latex as secondary gelling agent (foam stabilizer) in the silico-flouride foam process.
Industrial Applications
Tire & Rubber Products
DPG can be used as a secondary accelerator in tire compounds and other rubber products to support the vulcanization process.
Rubber Hoses & Belts
It is suitable for rubber hoses, conveyor belts, transmission belts and other industrial rubber products.
Rubber Footwear
DPG can be incorporated into rubber footwear formulations to help achieve the required curing characteristics.
General Rubber Goods
It can also be used in seals, gaskets, molded rubber products and other general rubber applications.
Packaging
25kg plastic woven bag, paper with plastic film bag, kraft paper bag.
Storage Conditions
Keep container tightly closed in a cool, well-ventilated place. The recommended maximum storage life is 2 years when stored under normal conditions.
