Martinal® OL-104C & Martinal® OL-107C - Flame retardants


Aluminium hydroxide - halogen free flame retardant.


MARTINAL OL-104 LEO and OL-107 LEO are new fine precipitated aluminum hydroxide grades with improved compounding performance, higher thermal stability, better powder flowability and higher bulk density after conveying, as well as lower compound viscosity. Target polymers are polyolefins and their copolymers, PVC and Rubber.

Aluminium hydroxide finds use as a fire retardant filler for polymer applications. It is selected for these applications because it is colorless (like most polymers), inexpensive, and has good fire retardant properties. It decomposes at about 180 °C (356 °F), absorbing a considerable amount of heat in the process and giving off water vapour. In addition to behaving as a fire retardant, it is very effective as a smoke suppressant in a wide range of polymers, most especially in polyesters, acrylics, ethylene vinyl acetate, epoxies, PVC and rubber.
