DPG Rubber Accelerator and the Science of Faster Vulcanization

DPG Rubber Accelerator and the Science of Faster Vulcanization

The strength, elasticity, and durability of rubber products depend heavily on the vulcanization process. Vulcanization transforms raw rubber into a material that can withstand heat, pressure, and stress. To speed up and control this process, manufacturers use special rubber accelerators — one of the most important being the DPG rubber accelerator.

DPG (Diphenyl Guanidine) plays a vital role in rubber compounding, acting as a secondary accelerator that ensures faster vulcanization, improved efficiency, and consistent quality in finished rubber products.


What is DPG Rubber Accelerator?

DPG accelerator is a guanidine-based chemical widely used in the tyre industry and industrial rubber production. Unlike primary accelerators such as MBT or CBS, DPG functions as a secondary accelerator that enhances performance, particularly in sulfur vulcanization systems.

Why DPG Accelerator is Critical in Vulcanization

Vulcanization without accelerators can take hours, making it impractical for mass production. DPG reduces this time drastically and ensures faster, controlled curing.

How DPG Works in the Vulcanization Process

DPG functions by boosting the activity of primary accelerators and ensuring stronger sulfur cross-links within the rubber. This chemical synergy results in faster vulcanization and better physical properties of rubber.
