Abstract
This invention relates to metal composite panels and to a core composition, or core filler composition, used for making them.

A core composition comprising:
- a polymer, a lubricant selected from the group consisting of fatty acids, fluoropolymers, metallic fatty acids, paraffin wax, polyethylene wax, polysiloxanes, polyalkylsiloxanes and polyorganosiloxanes with functional groups, and greater than or equal to about 90 wt % of a flame retardant comprising aluminum hydroxide (ATH);
- wherein:
- the ATH has a particle size distribution characterized by a d50 ranging from about 75 μm to about 150 μm, a d10 ranging from about 40 μm to about 70 μm, and a d90 ranging from about 100 μm to about 200 μm.
