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.
SOCAR Polymer, based in Azerbaijan, is currently 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.
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.
SOCAR Polymer started using Milliken additives after they were recommended by its licensor. During product development, the company decided to completely redevelop its RCP grades intended for TWIM applications. The resin maker re-engineered its products and introduced Millad NX 8000 to its formulation recipe. Milliken provided samples for development, and the two parties met at the K 2019 trade show in Dusseldorf to confirm the plan to proceed.
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.
Additionally, these Millad NX 8000-modified grades can be processed at lower temperatures and 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.
The excellent flowability of these grades makes them ideal for high-transparency TWIM packaging applications such as caps and closures, containers, and housewares.
Established in 2013, the SOCAR Polymer company has constructed and is operating two polymer production units with all the associated infrastructure in place: a Polypropylene production unit capable of producing 184 kilotons per annum on the basis of the Spheripol Process technology licensed by LyondellBasell and an HDPE unit with the design capacity of 120-kilo ton per annum based on the Innovene S technology licensed by INEOS. Its product strategy is oriented towards the production of competitive goods, with a focus on export development and substitution of imports. Following the first export of products in October of 2018, SOCAR Polymer kept expanding the geography of its sales market to include Russia, Turkey, Ukraine, Belarus, Lithuania, Poland, Uzbekistan, China, Turkmenistan, Georgia, Austria, and Romania. Product quality is controlled at every stage of production by a well-equipped Laboratory located on the site.
