Pallet with fire retardant and method of manufacture

Abstract

A plastic pallet having a fire retardant. The fire retardant is prepared in an FR masterbatch before mixing with HDPE to form the pallet. In one embodiment, the FR masterbatch includes a brominated fire retardant, a hydrated mineral, antimony trioxide and a carrier resin. In some embodiments, the brominated fire retardant is a non-blooming brominated fire retardant such as poly pentabromobenzyl acrylate or ethylenebistetrabromophthalamide. The hydrated mineral advantageously enhances both the vapor phase and condensed phase fire retardant properties of the final product and may be magnesium hydroxide. In other embodiments, melamine pyrophosphate or a blend of melamine pyrophosphate and polyhydric compound may be substituted for the hydrated mineral or used as the sole fire retardant. The polyhydric compound may be bis-pentaerythritol phosphate alcohol. A method of manufacturing a plastic pallet is also disclosed.
