How to build a compliant cure for medical, food-contact and infant rubber goods without nitrosamine-generating accelerators.

The regulatory pressure

EU 2023/1462 and REACH restrictions push nitrosamine levels in rubber articles down to the low-ppm range. Traditional TMTD/TMTM and secondary accelerator DPG are under scrutiny.

A practical system

Replace thiurams with TBzTD-70 (a non-nitrosamine alternative) and ZDBDC-80 for fast cure, and drop DPG in favor of primary sulfenamides such as TBBS-80.

Applicable compounds

NR, EPDM and NBR seals, stoppers, tubing and baby-care items. Verify extraction values per ISO 10993 / FDA 21 CFR where required.

Trade-off to expect

Scorch safety is usually improved, but the optimal cure rate needs rebalancing with sulfur and activator levels.
