Pinfa member company, A. Schulman, leading international supplier of high-performance plastic compounds, composites and resins, has developed a new PIN flame retardant polyethylene compound powder for rotomolding offering UL94 V-0 fire performance. Rotational molding (rotomolding) is a specific plastics production process where the plastic is input as a powder (not pellets) and melts in the mold (rather than being input into the mold as a hot liquid) with a mold with biaxial rotation (rotated simultaneously in two planes) so enabling low operating pressures, cheap and simple molds. This results in stress-free items with well controlled wall thickness and very low plastic wastage. Applications include storage tanks, containers, industrial and automotive parts, toys, sports equipment, amongst others, both large and small and with complex shapes. A. Schulman’s new PIN FR polyethylene rotomolding compound combines fire performance and processing qualities with non-halogenated formulation.
