Papua New Guinea Pre-dispersed accelerator DPG-80

The scorch time of the pre-dispersed accelerator DPG-80 is long and the vulcanization speed is slow, which will cause slight discoloration and cannot be used in light-colored products unless used as an active agent. When the pre-dispersed accelerator DPG-80 is used alone, the vulcanizate has poor thermal oxidative aging resistance (effective antioxidant is required); The pre-dispersed accelerator DPG-80 can effectively activate thiol accelerator. The pre-dispersed accelerator DPG-80 has no vulcanization promotion effect on butyl rubber IPDM and ethylene propylene rubber EPDM.

Product characteristicsThe scorch time of the pre-dispersed accelerator DPG-80 is long and the vulcanization speed is slow, which will cause slight discoloration and cannot be used in light-colored products unless used as an active agent. When the pre-dispersed accelerator DPG-80 is used alone, the vulcanizate has poor thermal oxidative aging resistance (effective antioxidant is required); The pre-dispersed accelerator DPG-80 can effectively activate thiol accelerator. The pre-dispersed accelerator DPG-80 has no vulcanization promotion effect on butyl rubber IPDM and ethylene propylene rubber EPDM.

Processing characteristicsUnder normal circumstances, powdered DPG is easy to fly and adhere to equipment, and it is not easy to disperse evenly during mixing.

The DPG-80 of bulk accelerator is easy to mix ingredients, will not agglomerate under normal storage conditions, has good fluidity, no dust flying, and will not cause feeding loss. Eating materials in various rubber materials is easy and evenly dispersed, ensuring the activity of effective component DPG; It is recommended to add them at the end of mixing.

DosageMain accelerator: 1.0-2 parts and 2.5-3.5 parts of sulfur;

Second accelerator: 0.1-0.25 parts, 0.75-1.0 parts of thiol accelerator and 2.5 parts of sulfur.

ApplicationVarious industrial technology products, rubber products containing white fillers.

PackagingComposite paper bag, lined with plastic film bag, net weight 25kg.

StorageSealed and stored in a cool, dry, well-ventilated place, avoid direct sunlight, and can be stored for 1 year.

Safety and toxicityPlease refer to the relevant product safety data (MSDS).
