  • Flame retardant polyolefin pallets and flame retardant master batch for their production
    Patent number: 6998433
    Abstract: Polyolefin-based pallets capable of passing standard pallet flammability tests are prepared by molding the pallet or one or more subassemblies thereof, of a polyolefin molding resin containing a flame retardant package containing magnesium hydroxide, and optionally alumina trihydrate, and zinc borate. The flame retardants may be supplied as a master batch at a concentration higher than that desired in the pallet or subassembly, in a polyolefin-compatible polymer, and result in pallets having a significantly lower heat release rate.
