The company’s North American business unit, Nabaltec USA, has manufacturing operations located in Corpus Christi, Texas (Nashtec LLC) and Chattanooga, Tennessee (Naprotec LLC).

Naprotec LLC is a large-capacity plant dedicated to the production of a wide range of alumina trihydrate (ATH) based flame retardants. Naprotec products include standard ground particle distributions, silane surface modified grades and enhanced- or optimized-viscosity ATH products.

Naprotec’s ATH-based products reportedly serve as multifunctional flame retardants and smoke suppressing extenders in a wide range of applications, like thermosets, thermoplastics, rubber, adhesives, sealants and coatings. The division manufactures Apyral ground hydrates, Apyral mixed hydrates and Apyral surface-treated hydrates.

According to the company, the ground hydrates come in a wide range of particle sizes; the mixed hydrates are formulated to achieve very high loading levels by minimizing viscosity increase; and the surface-treated hydrates offer surface-tailored reactive, non-reactive, hydrophilic and hydrophobic options.
