New at the K show: Cyclic olefin copolymer optimized for tough applications

Advancements in this supplier's metallocene catalyst technology have enabled it to develop new grades for both injection molding and blowmolding that are said to offer enhanced processability, high heat resistance and superior aesthetics. Applications are foreseen in the medical and food packaging fields, among others. The supplier, TOPAS Advanced Polymers, will unveil the new materials next week at the plastics industry's leading exhibition, the K show (Oct. 27-Nov. 3) in Düsseldorf, Germany. TOPAS is at the K at Stand 8aC28.

TOPAS 6013M-07, the first grade made using the new metallocene catalysts, provides a wide injection molding-processing window and doesn't require the use of an external lubricant for injection blowmolding (IBM) and injection stretch blowmolding (ISBM) applications. The material is also being considered for extrusion blowmolding (EBM).

Speaking about the company's new metallocene catalyst technology, Matthias Bruch, R&D director for TOPAS Advanced Polymers, said, "This technology sets a new standard for processing and performance while maintaining TOPAS' traditional purity and thermal properties without lubricant additives." The new grade has a heat distortion temperature (HDT) of 130°C and the typical clarity associated with COC. It can be used for monolayer and multilayer barrier bottles for the medical and food industries along with non-barrier uses such as baby bottles.

The new material is expected to be suitable with all standard methods of sterilization including gamma, EtO, steam, and hydrogen peroxide. It also has the potential to meet the temperature demands of microwave use. It complies with USP Class VI requirements for medical use, ISO 10993 for biocompatibility, and U.S. FDA food-contact regulations. Commercial quantities have been produced at TOPAS Advanced Polymers' plant in Oberhausen, Germany, and product is currently available worldwide.
