New PP based on Milliken's clarifier technology launched for transparent moulded parts
Carmel Olefins Ltd (BAZAN Group) has announced the launch of a new polypropylene (PP) grade its says offers both excellent transparency and high impact performance to injection moulded applications.
The company says its advanced features are complemented with good resistance to stress whitening, high gloss and excellent organoleptic performance.
New Capilene CT 80A is a clarified and antistatic modified PP grade with a melt flow rate (MFR) 25, produced with Milliken’s clarifier technology Millad NX 8000. It is the first in a new series under development by Carmel to enhance its existing portfolio of PP copolymers based on Millad NX 8000.
Capilene CT 80A is said to combine excellent flow with many of the typical advantages of PP random and heterophasic copolymers to achieve “outstanding transparency” plus very high gloss with a good stiffness/impact balance. Its ability to maintain such high transparency with good impact performance at 0°C is of particular significance for refrigerated applications.
Carmel Olefins says the overall performance advantages of the new grade create a step forward for converters looking to reduce breakage potential and avoid stress whitening of highly-transparent packaging and container solutions, for example, for thin wall packaging, clear containers for food packaging, caps & closures, and clear pails. It is also suitable for large storage boxes, crates, heavy duty transparent toolboxes, appliances and toys.
In addition, Capilene CT 80A is said to address converters’ sustainability requirements through its ability to deliver energy savings and shorten cycle times. The use of latest generation clarifier Millad NX 8000 allows a reduction in moulding temperatures compared to previous generation clarifiers. The temperature reduction delivers energy savings and also allows the cooling time of the part to be shortened prior to ejection from the mould. The resulting boost in productivity supports further energy savings, says Carmel Olefins.
The new grade brings about viable opportunities for customers to replace regular random copolymers in applications where optical property and impact resistance are required, the company added, as well as to replace heterophasic impact copolymers in applications where transparency should be combined with high impact or high impact without stress whitening.
Anita Vaxman, R&D and Technical Service Manager at Carmel Olefins, commented: “Capilene CT 80A takes the impact performance of our existing transparent PP grades to a new level. The innovation opens up new prospects for customers serving the food and non-food containers and houseware segments to produce attractive transparent articles that are less prone to breakage during shipment and handling, while also benefitting from energy savings during processing. It is a drop-in solution that we are looking forward to introducing to the market.”
