SB‐36 Aluminium hydroxide (ATH)


Aluminium hydroxide - halogen free flame retardant.


SB-36 is a coarse, mechanically ground ATH used to suppress flame and smoke in applications such as latex, vinyl and urethane compounds.

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.
