| Product Data | Specific gravity 1.32. Bitter, flammable, toxic. Easily soluble in fermentation, ether, acetone, cyclohexanone, tetrahydrofuran, etc. Slightly soluble in various plasticizers for PVC, insoluble in water and carbon disulfide. Dissolve in an alkaline solution and fold-out in an acidic solution. |
| Application | This product is used as a fast vulcanization accelerator, the critical temperature of vulcanization is 80℃, and care should be taken to avoid early vulcanization when mixing. The activity is higher when the temperature is above 100℃. The products obtained are harsh, with excellent tensile strength and flexural resistance, but the products will be discoloured by light, mainly used in natural latex and neoprene products. It is also used as a heat stabilizer for emulsion polymerization of PVC, especially for soft products, and cannot be used with lead, cadmium and other stabilizers, otherwise it will lead to discolouration. It is a reagent for medicine, dye intermediates and testing osmium-rhodium products. |
| Storage | It should be stored in a cool, dry and well-ventilated place. Packaged products should be protected from direct sunlight and are valid for 1 year. |
| Packaging | 25kg plastic woven bags, paper-plastic composite bags, kraft paper bags. |
