  • Patent number: 8697801
    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.

  • Patent number: 7381357
    Abstract: The present invention is the apparatus and method for producing a plastic sheet having a pattern produced in a layer therein. The plastic sheet is a single layer sheet or a multi-layer sheet. The pattern is produced by mixing two or more plastic extrudants together in a mixer. The pattern is visible in the layer containing the two or more plastic extrudants because an at least one of the plastic extrudants is at least partially transparent. The mixer used to produce the pattern includes a housing having an end configured to expel the mixture of the two or more extrudants through a plurality of outlets. The mixer further comprises a rotatable shaft and at least one projection coupled to the shaft and rotatable with the shaft, the at least one projection configured to orient the mixture of the two or more extrudants relative to the plurality of outlets in the housing. The mixer further comprising a thrust bearing configured to couple an end of the shaft to the housing.
