Abstract
The invention relates to plastic pallets that pass the Underwriters Laboratory UL 2335 protocol for pallets wherein said pallets comprises at least one resin selected from the group consisting of: (a) polyphenylene ether resin and blends containing polyphenylene ether resin, (b) polycarbonate resin and blends containing polycarbonate resin, (c) vinyl aromatic graft copolymer resin; (d) polyetherimide resin and blends containing polyetherimide resin, and (e) thermosetting resins. In a preferred embodiment, the plastic pallet has an open deck design. The invention also relates to a method to make pallets that pass the UL 2335 protocol.
Claims13
A plastic pallet comprising:
- a polyphenylene ether resin;
- a high impact polystyrene;
- a linear low density polyethylene;
- at least one flame retardant in an amount sufficient to impart a degree of flame retardancy to the pallet to pass UL 2335 protocol for pallets;
- and
- at least one impact modifier,
- wherein the pallet meets or exceeds Underwriters Laboratory UL 2335 protocol for pallets.
A plastic pallet consisting of:
- polyphenylene ether resin;
- high impact polystyrene;
- at least one flame retardant;
- at least one additive, wherein the additive is selected from the group consisting of mineral filler, clay, reinforcing agent, glass fiber, glass flakes, glass spheres, plasticizer, stabilizer, colorant, processing aids, and a combination of the foregoing additives;
- and
- at least one impact modifier wherein at least one impact modifier is linear low density polyethylene;
- wherein the pallet meets or exceeds Underwriters Laboratory UT 2335 protocol for pallets.
A method for making a plastic pallet comprising:
- injection molding a composition comprising polyphenylene ether resin;
- a high impact polystyrene;
- at least one flame retardant in an amount necessary to impart a degree of flame retardancy to the pallet to pass the UL 2335 protocol for pallets;
- at least one impact modifier;
- and zinc oxide, zinc sulfide, or combinations of the foregoing, wherein the pallet meets or exceeds Underwriters Laboratory UL 2335 protocol for pallets.
