Guanidines-accelerator Dpg, also known as diphenylguanidine (DPG), is a primary or secondary accelerator used in the vulcanisation of natural and synthetic rubbers. This powdered compound appears as a white to pale yellow solid, soluble in acetone and benzene but only sparingly soluble in water, providing consistent performance in rubber formulations. It is commonly supplied in 25 kg paper bags with inner plastic liners to maintain stability during transport and storage.
As a guanidine-class accelerator, DPG is valued for its ability to activate vulcanisation at moderate temperatures, often used in combination with thiazoles or sulfenamides to achieve balanced cure rates. Typical applications include the production of tires, conveyor belts, hoses, and industrial rubber goods where a medium to fast cure is required. The standard purity for commercial-grade DPG is 95% minimum, with a melting point range of 145-150°C, ensuring reliability in industrial processes.
Importers of DPG primarily include tire manufacturers, rubber compounding plants, and producers of technical rubber goods. The product is non-hazardous under normal handling conditions but requires storage in a cool, dry, and well-ventilated area to prevent caking or degradation. Buyers should confirm packaging specifications and compatibility with their existing rubber formulations before bulk ordering.

Before ordering DPG from Qingdao Rensheng Huida Trading Co., Ltd., verify the exact purity, melting point, and solubility specifications to ensure they meet your production requirements. Request a certificate of analysis (COA) and confirm whether the product has been tested for common impurities that could affect vulcanisation. Check if the supplier can provide additional technical data sheets or sample batches for testing in your specific rubber compounds.
Confirm the packaging details, as DPG is typically supplied in 25 kg paper bags with inner plastic liners to prevent moisture absorption. Discuss Incoterms such as FOB Qingdao or CFR to your destination port, and clarify whether the supplier can accommodate smaller or larger bulk shipments. Lead times may vary, so agree on a timeline that aligns with your production schedule, and ensure the supplier can provide a bill of lading and other export documentation.
Conduct quality checks upon receipt by testing the DPG for purity, melting point, and solubility in your lab or through a third-party inspection service. For critical applications, consider arranging pre-shipment inspection in Qingdao to verify the product's condition before it leaves the supplier's facility. Ensure all documentation, including the COA, material safety data sheet (MSDS), and packing list, is complete and accurate to avoid delays during customs clearance or production.
