SOCAR Polymer has introduced two new impact copolymer polypropylene (ICP) grades ideal for rigid, thin-wall packaging such as caps, closures, and opaque containers, as well as for various housewares, sporting goods, and toys. Containing Milliken Chemical’s Hyperform® HPN® additive, the new CB 4848 MO (with a melt flow rate of 48) and CB 6448 MO (with a melt flow rate of 64) grades deliver molded parts that exhibit low shrinkage, improved thermal resistance (HDT), superior rigidity, dimensional stability, and an excellent balance between stiffness and impact resistance. With their good flowability, they enable faster processing and reduction of energy usage, while allowing both newer and older injection molding machines to efficiently process the material.
The two new grades are currently marketed to customers in Russia, Turkey, and CIS.
SOCAR Polymer has worked collaboratively with the Milliken company for a year to provide customers with these reactor grades of heterophasic copolymers, which use no organic peroxides, and abide by SOCAR Polymer’s zero-phthalate philosophy, meaning that no catalysts and chemicals containing phthalate compounds are used at any stage of production. The collaboration built upon the previous cooperation between the companies that late last year led to the introduction of SOCAR’s first two random copolymer PP grades – RB 4545 MO and RB 6545 MO. Those grades use Milliken’s Millad® NX® 8000 family of clarifiers to boost clarity in TWIM packaging products while maintaining an excellent balance of overall properties.
