| Chemical Composition | N-N’-diphenylthiourea |
| Appearance | white powder |
| Features | This product is used as a rapid vulcanization accelerator. The critical temperature of vulcanization is 80℃. Care should be taken to avoid early vulcanization during mixing. It is mainly used as an accelerator in CR and EPDM to replace ETU, and it is an environmentally friendly accelerator. The activity is higher when the temperature is above 100℃. The obtained product is tough, excellent in tensile strength and flexural resistance, but the product will be discolored by light, and it is mainly used in natural latex and neoprene latex products. This product is also used as a heat stabilizer for polyvinyl chloride in emulsion polymerization, especially for soft products. It cannot be used together with stabilizers such as lead and cadmium, otherwise the product will be discolored. |
| Usage | 0.5~2PHR |
| Purpose | Suitable for CR, EPDM and other compounds |
