SOCAR Polymer has expanded its portfolio of high-performance polypropylene resins with the addition of its first pair of random copolymers (RCPs). These resins are designed to yield rigid packaging via thin-wall injection molding (TWIM), along with a host of other benefits.
High Quality Products for TWIM Items
The two new grades are
RB 4545 MO (with a melt flow index of 45) and
RB 6545 MO (with a melt flow index of 65). Those viscosities account for the majority of TWIM items made from random copolymers, according to Milliken, whose Millad® NX® 8000 family of clarifiers imparts many of the key properties to the resins.
The aim of these materials is to provide the best possible balance between processability, good mechanical and optical properties, along with high-end aesthetics and excellent safety of the final molded products. The use of the Milliken clarifier provides superb transparency and clarity to the resulting resins, which enables the replacement of other plastic materials with the highly recyclable PP.
The very good flowability of these grades make them ideal for high-transparency TWIM packaging applications such as caps and closures, containers and housewares.
Energy Saving in Packaging Production
Additionally, these grades can be processed at lower temperatures, and for shorter cycle times, which translates into energy savings for the injection molder. This independently verified lower energy usage allows brand owners to apply the UL Environmental Claim Validation label on injection molded packaging made with these PP resins, further emphasizing their sustainability commitment.
These latest SOCAR Polymer PP grades also yield parts with an excellent balance between stiffness (rigidity) and impact resistance, as well as with good antistatic and mold-release properties. They are food contact-approved, 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.
SOCAR Polymer, based in Azerbaijan, currently is marketing these materials to customers in Russia and other countries in the Commonwealth of Independent States. The company suggests that these new RCP grades will qualitatively complement its portfolio of PP products intended for the segment of rigid packaging produced by thin-walled injection molding.
