SABIC® PP QR674K is a high melt flow index random copolymer with excellent transparency and good antistatic properties. This grade combines improved aesthetics of the finished articles with low temperature processability and a very good organoleptic performance. Part aesthetics are not affected by the lower temperatures, providing for a broader operating window. The SABIC®PP QR674K presents excellent flow behaviour, easy demoulding and good stiffness to impact ratio.
SABIC® PP QR674K is mainly used in injection moulding processes. The SABIC® PP QR674K aims at transparent applications were higher MFI's with good flow are required. Its intended applications include injection moulded housewares, office & home storage boxes, thin wall packaging, lids and caps & closures.
The product mentioned herein is in particular not tested and therefore not validated for use in pharmaceutical/medical applications.
