ALUMINUM TRIHYDRATE, working for a better environment



ATH is used in polyester resins.  However with increased attention being given to smoke & toxic fume emissions, ATH has found large volume application in  vinyl as a low  smoke, non toxic replacement for antimony and in polyurethane, latex, neoprene foam system,  Rubber, wire & Cable insulation, vinyl walls & flooring coverings and epoxies. 

Alumina Trihydrate acts as a flame retardant and smoke suppressor because of its thermodynamic properties.  Its endothermic dehydration cools the plastic & Rubber parts and dilute with water vapour those combustible gases that do escape. 

The latter is probably the main phenomenon associated with smoke suppression other excellent performance include electrical and track resistance.

TOR Minerals: high versatility of applications


Our ATH, Boehmite, Titanium Dioxide and Barium Sulfate have the power to be transformed in many different and incredible results. If you are a manufacturer and you are looking for the best raw materials for your business, pay attention to this article and discover the quality of the best specialty minerals. 

ALUPREM, Premium Aluminum Trihydrate and Boehmite.

These products are suitable for a broad range of applications including Wire & Cable, Printed Circuit Boards, Catalysts, High-Tech Polishing, Coatings and Pigments. Performance benefits include high temperature flame retardant, improved mechanical properties & scratch resistance, good resin compatibility and high brightness.

One of the most important applications of our ATH is the Solid Surface manufacture. Part of the amazing and modern design our clients obtain in their products is thanks to the high quality and high standards of our minerals. See some of these applications here

TITANIUM DIOXIDE, our unique and innovative colored mineral.

Unique, Beige and Gray Colored TiO2 Pigments offer formulation cost savings for paints and coatings (architectural, industrial, metal finishes, powder coating, coil backers, primers and wood coatings), sealants, floor tiles, PVC and plastics master batch.

Barium Sulfate’s high density is one of the primary reasons it is used as a Pigment. Suitable for use in both acid and basic conditions, BARTEX gives weight and body to products ranging from Powder Coatings to Rubber products (floor mats and curtain backings) and Plastics (poker chips and billiard balls). BARTEX is also used as an extender pigment in top coats and primers.

Alumina Trihydrate (ATH) and Boehmite (AMH) halogen-free flame retardant & smoke suppressant fillers for plastics, rubber and specialty applications.

Non-toxic, non-corrosive Alumina Trihydrate (ATH) and Boehmite (AMH) flame retardant and smoke suppressant fillers function on the principal of heat- activated decomposition into aluminum oxide and water. During fire conditions, water vapor is released via an endothermic reaction which acts to cool the surface and displace oxygen required for burning. The resulting aluminum oxide char barrier further hinders combustion and reduces smoke density.

Alumina Trihydrate is the most widely used and increasingly important, environmentally friendly flame retardant in the market. Thermal decomposition occurs at about 200°C, making it suitable for a broad range of plastics and rubber applications. Specialty low viscosity ATH is available for meeting the most stringent performance requirements for a variety of composite processes, substituting halogenated flame retardants. For higher temperature polymers or processing conditions, boehmite is thermally stable to > 300°C and offers excellent mechanical properties, high heat capacity and good resin compatibility.
