ATH Powder Supplier India | Aluminium Trihydrate (Hindalco)

Aluminium hydroxide ATH powder (Hindalco and equivalent grades) from Drashti Chemicals serves flame-retardant filler in wire-cable compound, solid-surface countertops, and thermoplastic formulations across Gujarat. ATH releases water of hydration at 200 °C, diluting combustible gases — the standard halogen-free flame retardant for export cable meeting IEC 60332.

1 µm median particle size for wire compound extrusion; 3–5 µm for moulding grades; surface-treated (silane-coated) ATH for higher loading without viscosity spike. Hindalco ATH carries consistent particle size distribution — critical for die pressure stability on extrusion line. COA confirms Al(OH)₃ content, particle size (D50), and moisture.

Loading levels: 50–70% by weight in halogen-free cable compound with EVA or LLDPE base; 40–60% in solid-surface polyester matrix. Untreated ATH above 55% loading increases melt viscosity — switch to surface-treated grade or add processing aid. Store dry — moisture causes pre-reaction during compounding and voids in extrudate.

Packaging: 25 kg HDPE bags, jumbo bags for 20 MT+ monthly. MOQ one bag; bulk quote on request for cable manufacturers in Vadodara and Halol GIDC. COA and MSDS per lot. GST 24AGLPC6288M1ZX. Drashti Vadodara consolidates Hindalco ATH with other flame-retardant additives for single-PO convenience.

ATH vs. MDH (magnesium hydroxide): ATH decomposes at lower temperature (200 °C) — suits PE and EVA; MDH stable to 300 °C — suits PP and engineering plastics. ATH vs. brominated flame retardant: ATH is halogen-free, lower smoke toxicity, heavier loading required. For cost-down, never substitute ground calcium carbonate — no flame-retardant function.
