New resin know-how boosts COC material performance - company
The German company said its Topas 6013M-07 is the first grade to employ the new resin technology. The product provides a wide injection moulding processing window and does not need an external lubricant for either injection blow moulding (IBM) or injection stretch blow moulding (ISBM) applications, said the firm.
Topas added that the material was also being considered for extrusion blow moulding.
Technical advancements
The Frankfurt-based company said advancements in its metallocene catalyst technology had made the development of the new material possible. Topas said the breakthrough produced material that was both easier to process and had a better appearance.
“This technology sets a new standard for processing and performance while maintaining Topas’ traditional purity and thermal properties without lubricant additives,” said company R&D director Dr Matthias Bruch.
The firm said the material was suitable for monolayer and multibarrier bottles for food applications thanks to a heat distortion temperature (HDT) of 130°C and its “excellent” clarity properties.
“The new material is expected to be suitable with all standard methods of sterilisation including gamma, EtO, steam, and hydrogen peroxide,” said Topas. “It also has the potential to meet the temperature demands of microwave use.”
Commercial quantities have already been produced at its German plant and product is available for shipment worldwide, said Topas, which is showcasing the material at the K2010 trade fair in Dusseldorf, Germany, 27 Oct- 3 Nov.
