Touching lives, enhancing safety

Both aluminum oxide and aluminum hydroxide are very good insulator materials, with a low dielectric loss factor and high dielectric strength.

Functionalities in electrical properties

Technical ceramics made from Martoxid® calcined aluminum oxides provide highest thermal resistance, mechanical strength, extreme hardness, excellent resistance to wear, corrosion, excellent thermal conductivity and good electrical insulation. Our materials are available as unground, ground and superground grades, as well as ready-to-press granules. 

Martinal® and Magnifin® grades have extremely low electrolyte content and therefore are the ideal choice for use in wire and cable insulation compounds. They provide highest volume resistivity even when in contact with water. In addition to their outstanding electrical properties, our Martinal® and Magnifin® products exhibit high thermal stability, outstanding compounding performance and good flowability.
