RUBBER CHEMICALS DPG Granule

Chemical Name: Diphenyl guanidine

It appears as grayish‑white powder or granules. It is odor‑free and non‑toxic, with a density ranging from 1.08 to 1.19. This substance is soluble in acetone, ethyl acetate and ethanol, slightly soluble in carbon tetrachloride, and insoluble in gasoline and water.

• Vulcanization Accelerator: DPG is mainly used as a medium‑speed accelerator for natural rubber and synthetic rubber. It improves                      vulcanization efficiency and the aging resistance of rubber.
• Activator: When combined with thiazole, thiuram and sulfenamide‑type accelerators, DPG acts as an activator to boost vulcanization performance.
• Plasticizer and Peptizer: For neoprene rubber, DPG also functions as a plasticizer and peptizer.

 

 

 

 

As a sulfur‑based vulcanization accelerator, diphenylguanidine speeds up rubber vulcanization to raise vulcanization efficiency, which shortens production cycles and boosts manufacturing productivity. It also optimizes the physical‑mechanical performance of rubber articles, lifting tensile strength, tear strength and wear resistance for extended service life of finished goods. Responding to growing environmental‑protection demands, modern‑grade diphenylguanidine is formulated to lower hazardous‑substance levels and comply with global environmental norms, guaranteeing product safety and sustainability. Compatible with multiple rubber systems covering natural rubber and synthetic rubber, it finds extensive application in manufacturing rubber goods including tires, hoses and conveyor belts.

Keep container tightly closed in a cool, well-ventilated place. The recommended maximum storage life is 2 years when stored under normal conditions.

Q1: How does DPG improve the aging resistance of rubber products?

DPG optimizes the cross-linking density of rubber molecular chains during vulcanization, forms a stable network structure, and reduces molecular chain aging and cracking caused by heat and mechanical friction. Therefore, it significantly enhances the thermal aging and fatigue resistance of finished rubber goods.

Q2: What changes will occur to rubber's physical performance after adding DPG?

Proper addition of DPG can effectively increase the tensile strength, tear strength and abrasion resistance of rubber compounds. It also stabilizes product hardness and dimensional stability, greatly extending the service cycle of rubber products.

Q3: What special processing functions does DPG have in neoprene rubber?

Besides accelerating vulcanization, DPG acts as a plasticizer and peptizer for neoprene. It improves rubber fluidity during processing, reduces mixing difficulty, and optimizes the molding processability of neoprene products.

Q4: What are the advantages of DPG in industrial rubber product production?

DPG stabilizes vulcanization speed, shortens production cycles, and improves manufacturing efficiency. Meanwhile, it enhances product mechanical strength and aging resistance. Modern low-hazard DPG grades also meet international environmental standards, balancing production efficiency and product safety.

Q5: What are your core advantages compared with other DPG manufacturers?

We adopt standardized production and strict quality control system for DPG products, featuring stable purity, low impurity content and consistent batch stability. Different from ordinary products, our optimized formula effectively guarantees rubber vulcanization stability and product aging resistance. Meanwhile, we support customized indicators and flexible packaging solutions to meet diverse industrial production needs.

Q6: Do you support sample orders and small trial orders for DPG?

Yes. We fully support free sample testing and small trial orders. It allows customers to verify product performance, compatibility with existing rubber formulas and final product quality before bulk procurement, effectively avoiding batch risks and ensuring stable follow-up production.
