What is Aluminium Trihydrate?
Aluminium Trihydrate (ATH), chemically known as Aluminium Hydroxide, is one of the most widely used flame retardant and smoke suppressant fillers in the global plastics, rubber, and coatings industries. It is a white, fine powder that functions as a flame retardant through a unique endothermic decomposition mechanism: when exposed to fire temperatures around 200°C, it absorbs heat and releases water vapour, simultaneously cooling the material and diluting combustible gases, while also forming a protective alumina char layer.
Polychem Industries supplies Aluminium Trihydrate to cable and wire manufacturers, plastics compounders, rubber producers, and paint and coating formulators across India and internationally. As one of the most cost-effective, non-toxic, and halogen-free flame retardant fillers available, ATH has become the flame retardant of choice across numerous industries seeking to meet fire safety standards without the environmental and health concerns associated with halogenated flame retardants.
Available Grades
| Grade | Form | Purity | Standard | Applications |
|---|---|---|---|---|
| Industrial Grade | White fine powder | 99%+ (Industrial Grade) | Industrial | Flame retardant filler, cable compounds, plastics, paints |
Applications & Uses
Cable & Wire Compounds
One of the most significant applications. ATH is used extensively as a flame retardant filler in low-smoke, halogen-free cable and wire insulation and sheathing compounds, particularly important in cables used in public buildings, transportation, and other applications where fire safety and low smoke/toxic gas emission are critical.
Plastics & Polymer Compounds
Used as a flame retardant filler in various plastic compounds including polyolefins, unsaturated polyester resins, and other polymers requiring fire-retardant properties for building materials, electrical enclosures, and other fire-safety-critical applications.
Paints & Coatings
Used as a functional filler in fire-retardant paint and coating formulations, contributing both to flame retardancy and to the overall opacity, gloss control, and physical properties of the coating film.
Rubber Compounds
Used as a flame retardant and reinforcing filler in rubber compound formulations, particularly for applications requiring fire safety performance such as certain automotive, construction, and industrial rubber products.
Building & Construction Materials
Used in various building materials requiring fire-retardant properties, including certain composite panels, sealants, and construction products where fire safety regulations require flame-retardant performance.
Surface & Engineered Stone Products
Used as a filler in engineered stone and solid surface countertop products, contributing to the physical properties, fire resistance, and overall performance of these composite materials.
