TAGS: Formulations and Transparency
SOCAR Polymer has expanded its portfolio of high-performance polypropylene resins with the addition of its first pair of random copolymers (RCPs). Milliken’s Millad® NX® 8000 family of clarifiers imparts many of the key properties to the resins. These resins are designed to yield rigid packaging via thin-wall injection molding (TWIM), along with a host of other benefits.
Clarifiers for Transparency and Clarity
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.
Energy Savings for Injection Molders
Additionally, these Millad® NX® 8000-modified 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.
The very good flowability of these grades make them ideal for high-transparency TWIM packaging applications such as caps and closures, containers and housewares.
