Can I blend ATH and MDH in the same formulation?

Yes. Many LSZH cable compounds use 70:30 or 80:20 ATH:MDH blends to balance cost, loading efficiency, and processing margin.

Which is better for PVC?

ATH is the standard for PVC flame retardancy. MDH is less common because PVC is typically processed at 160 to 200°C, well within ATH's stability window.

Does MDH produce different decomposition products?

MDH decomposes to MgO + H2O, similar to ATH's Al2O3 + H2O. Neither produces toxic gases. Both leave a mineral residue.

Is there a price premium for surface-treated grades?

Yes, 20 to 30% premium for both ATH and MDH. Surface treatment is critical for loadings above 50 wt% in polyolefins.

What is the minimum order quantity?

1 MT for standard grades, 5 MT for custom surface treatments. Trial samples of 1 kg available for lab evaluation.
