Terracore Chemicals je dodavatel hydroxidu hlinitého for manufacturers formulating flame retardant plastics, rubber, and cable compounds. Also known as Aluminum Trihydrate (ATH) or ATH flame retardant filler, this is the most widely used non-halogenated flame retardant filler in the industry, valued for its combination of flame retardancy, smoke suppression, and cost-effectiveness relative to alternative flame retardant chemistries.

ATH works by decomposing endothermically at around 180-200°C, releasing water vapor that cools the polymer matrix and dilutes flammable gases at the burn front — a mechanism that also produces less smoke and toxic gas than halogenated flame retardants, which is why ATH is the standard choice in applications like cable insulation where smoke density is a critical safety specification.

As an aluminum hydroxide supplier working across the plastics, rubber, and cable industries, Terracore Chemicals offers flame retardant grade ATH with particle size options to suit different loading levels and processing requirements. Full technical data on the compound, including solubility, particle size distribution methods, and safety classification, is available via PubChem.

Technické specifikace

ATH from Terracore Chemicals — your aluminum hydroxide supplier — meets standard flame retardant filler grades. Key physical parameters: specific gravity 2.42 g/cm³; refractive index 1.57; pH (10% slurry) 9.0–10.5; moisture content <0.5%; loss on ignition 34.6% (corresponding to the three hydroxyl groups released as water on decomposition). Particle size grades range from superfine (<2 µm median) through standard milled grades (typically 10–50 µm) to coarse-ground material, allowing formulators to optimise filler loading, rheology, and surface finish in their compound.

Why Use a Non-Halogenated Flame Retardant?

Regulatory pressure under RoHS, REACH, and the EU Construction Products Regulation has pushed cable and plastics manufacturers away from brominated and chlorinated flame retardants toward halogen-free alternatives. ATH is the benchmark halogen-free choice: it passes UL 94 V-0 and IEC 60332 cable flame tests at typical loadings of 40–65% by weight in EVA, PE, or PVC compounds, and it generates minimal corrosive HCl or HBr gas during combustion — a key requirement in public spaces, tunnels, and rolling stock where toxic smoke is a life-safety concern.

Zdroje a dodávky

As a direct aluminum hydroxide supplier, Terracore Chemicals ships ATH in 25 kg multi-wall paper bags and 50 kg woven polypropylene bags. Bulk bag (jumbo bag / FIBC) supply is available for high-volume compounders. Each consignment is accompanied by a Certificate of Analysis (COA) covering purity, moisture, and particle size distribution. We work directly with production-level manufacturers and accept orders from 1 MT trial quantity through to full container loads (FCL), with competitive pricing on multi-shipment contracts.
