(sabic) -- To meet the need of converters for materials that deliver better finished products and that can be produced cost-effectively, SABIC has developed two new high clarity SABIC PP Qrystal polypropylenes. These random copolymers, typically for injection moulding, were specially designed with unique flow behavior, providing processors with the flexibility to produce parts faster and with lower energy consumption.
SABIC PP QR674K, with a melt flow rate (MFR) of 40g/10min, was typically developed for more sensitive food contact applications, owing to its improved organoleptic performance low odor. Typical target applications are caps and closures, houseware, kitchenware and food/non-food containers.
SABIC PP QR678K, with its high MFR of 80 g/10 min, is better suited to production of parts with complex shapes and/or long and narrow flow paths. Customer trials have shown around 15% higher flow than a standard PP random at the same MFR level, allowing machines to run at lower processing temperatures and 15% faster cycle times, potentially decreasing production costs.
SABIC has a broad package of PP random copolymers that provide solutions for a wide range of applications, providing a combination of good transparency with lower conversion costs. The SABIC PP Qrystal range, which was launched in 2010, now comprises four grades, with MFRs ranging from 25 to 80 g/10 min.
