| Latex | 0.3 - 1.0 phr |
| As Secondary Accelerator | 0.1 - 0.2 phr |
| Justification | Description |
|---|---|
| No Nitrosamine Risk | ZDMC is one of the accelerators that does not form nitrosamines. Therefore, it is preferred in medical products (gloves, catheters) and food-contact rubbers. |
| Low Temperature Curing | In latex systems, when low-temperature vulcanization is required, it is an indispensable accelerator. Alternatives do not provide sufficient curing. |
| High Dispersion | Predispersed (masterbatch) form ensures homogeneous mixing and process stability, making it standardized in some production lines. |
| Regulatory Compliance | Authorities such as the EU and US FDA mandate the use of nitrosamine-free accelerators in certain products. ZDMC meets this requirement. |
| Medical and Hygienic Products | Its use in sensitive applications such as gloves, medical hoses, and baby products is mandated by certification and customer demand. |
| No Odor or Discoloration | It is odorless and does not cause discoloration. This is a major advantage in medical and consumer products. |
