| Product Data | Relative density is 1.66, soluble in dilute alkali, carbon disulfide, benzene, acetone and dichloromethane, slightly soluble in chloroform, insoluble in ethanol, carbon tetrachloride, and ethyl acetate. |
| Application | Super accelerator for natural rubber and synthetic rubber and general accelerator for latex. It is especially suitable for butyl rubber and nitrile rubber with excellent aging resistance which has requirements for compression deformation, and also for EPDM rubber. The vulcanization temperature is 100℃, and the activity is stronger than TMTD, but the activity is stronger at low temperatures, and the tendency of scorching is big, and it is easy to cause early vulcanization when mixing. It has an activation effect on the thiazole subsulfonamide accelerator and can be used as a second accelerator. When used with DM, with the increase in DM dosage, the anti-scorch performance also increases. Since it is tasteless, non-polluting and non-discolouring, it is suitable for rubber products for adhesive tape, food and medicine. In the United States, ZDMC has been approved by FDA. It is effective in EPDM, butyl rubber and other products. |
| Storage | 25kg plastic woven bags, paper-plastic composite bags, kraft paper bags. |
| Packing | It should be stored in a cool, dry and well-ventilated place. Packaged products should be protected from direct sunlight and are valid for 2 years. |
