LyondellBasell has added a high clarity, polypropylene-based copolymer to its family of metallocene-based resins. The Metocene RM2231 resin is said to combine the clarity and gloss of PET with the density and recyclability of polypropylene. Injection moulded plaques of 1mm produced using Metocene RM2231 are claimed to show just 4% haze, exceeding previous benchmark values of 6-10% haze.
The new resin also provides improved surface characteristics in non-transparent applications and doesn’t require pre-drying or high temperatures, saving time and energy.
