Aluminium Hydroxide Supplier in India
Aluminium Hydroxide is an important inorganic raw material used across several industries because of its chemical characteristics and ability to perform different functions depending on grade and particle-size requirements. Pharmaceutical grades are used in specific medicinal formulations, while industrial grades can be selected for applications such as flame-retardant systems, plastics, rubber, paper and coatings.
We focus on supplying Aluminium Hydroxide according to the buyer's technical requirements rather than treating all grades as interchangeable. Before procurement, buyers should confirm the required purity, particle-size distribution, moisture, loss on drying, bulk density, applicable standard, packaging and intended end use.

Aluminium Hydroxide Applications
Aluminium Hydroxide is a versatile material with applications across pharmaceutical and industrial sectors. The appropriate grade should be selected based on the final product, processing conditions and required technical specification.
Pharmaceutical Applications
Aluminium Hydroxide is used as an active ingredient in certain antacid products and can also be used in specific pharmaceutical formulations. Pharmaceutical use requires the appropriate pharmaceutical grade and compliance with the applicable regulatory and pharmacopeial requirements.
Flame Retardant Applications
Aluminium Hydroxide, particularly Aluminium Trihydrate (ATH), is used as a mineral flame-retardant filler in selected polymer systems. Its suitability depends on particle size, loading, polymer compatibility and processing temperature.
Plastics & Rubber
Selected ATH grades are used as functional mineral fillers in plastics, rubber and polymer compounds where flame-retardant and smoke-suppression performance is required.
Paper & Coatings
Aluminium Hydroxide can be used as a filler or functional raw material in selected paper, coating and related formulations, depending on the required whiteness, particle size and surface characteristics.
Other Industrial Applications
Aluminium Hydroxide Grades
Aluminium Hydroxide is available in different grades and specifications. A suitable grade should be selected according to the final application rather than using a single specification for every industry.
Pharmaceutical Grade
Pharmaceutical applications require controlled quality and compliance with the applicable regulatory or pharmacopeial requirements. Buyers should specify the required pharmacopeia, purity and intended dosage-form application when requesting pharmaceutical material.
Industrial Grade
Industrial grades can be selected for applications such as polymer compounds, rubber, coatings, paper and other technical formulations. Particle size, moisture, purity and other parameters may be important depending on the application.
ATH / Aluminium Trihydrate
Aluminium Trihydrate (ATH) is a commonly used name for Aluminium Hydroxide in industrial flame-retardant and filler applications. Different ATH products can have significantly different particle-size distributions and performance profiles, so the technical specification should be reviewed before purchase.
How to Select the Right Grade
- Define the final application and processing method.
- Confirm required purity and applicable standard.
- Review particle-size distribution.
- Check moisture and loss-on-drying requirements.
- Confirm bulk density and handling requirements.
- Request a current Certificate of Analysis before approval.
- Confirm packaging and storage conditions.
Quality, Documentation & Packaging
Quality Documentation
For commercial procurement, customers can request the applicable technical documentation for the selected grade. Depending on product and order requirements, this may include a Certificate of Analysis (COA), Safety Data Sheet (SDS), product specification sheet and other relevant quality documents.
Key Parameters Buyers May Specify
- Aluminium Hydroxide purity
- Particle-size distribution
- Moisture / Loss on Drying
