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 combines 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.
The overall performance advantages and superior impact characteristics 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 addresses 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 molding 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 mold. The resulting boost in productivity supports further energy savings.
The new grade initiates viable opportunities for customers to replace regular random copolymers in applications where optical property and impact resistance are required, and 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, comments: "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."
