Metal Deactivators / Chelators

Metal Deactivators / Chelators (Irganox® MD 1024, Naugard® XL-1, EDTA derivatives)

Transition-metal ion passivators for extended polymer, lubricant, and fuel life*

Metal deactivators and chelators bind pro-oxidant transition metals (Cu²⁺, Fe³⁺, Mn²⁺) into stable, inert complexes—preventing catalytic hydroperoxide decomposition and Fenton-type radical formation. Essential for wire & cable insulation, metal-filled compounds, and fluids in contact with copper or steel.

Our line includes high-efficiency N-salicylidene hydrazides (Irganox® MD 1024), oxalyl bis(benzylidenehydrazide) (OBBH), triazole derivatives, and EDTA-free polymeric chelators. Supplied as low-dust powders, non-dusting granules, solvent-free liquids, and 10–25 % active masterbatches in PE/PP/PA carriers.

**Key Benefits**  
- **Catalytic Inhibition**: <1 ppm residual metal activity after 24 h contact  
- **Synergy**: 2–5× OIT boost when combined with phenolics/phosphites  
- **Non-Discoloring**: Copper-complex grades prevent green/blue tint in XLPE  
- **Heat Resistance**: Effective to 300 °C in PA6/66 glass-filled compounds  

**Typical Applications**  
- Wire & cable (XLPE, EPR, HFFR jackets)  
- Metal-filled plastics (Cu-powder PA, Fe-flake PP)  
- Synthetic lubricants (PAO + copper alloys)  
- Fuel additives (gasoline with copper lines)  
- Recycled streams (post-consumer PET with metal contaminants)  

All grades include TDS, SDS, COA, and metal-complex stability data.
