K2019 PREVIEW | POLYMERS AND ADDITIVES I
Right: Bieglo will show its range of food contact approved PEEK compounds
grades that provide the high melt strength required for extrusion and thermo- forming applications. Both new grades offer the high melting point, low water absorption, high dimensional stability and good barrier properties expected of PBT. Ultradur B6551 LNI is suitable for production of pipes, profiles and mandrels while Ultradur B6560 M2 FC TF is optimised for extrusion of films and thermoforming of packaging or technical parts. �

Bieglo will display a selection of high temperature PEEK compounds, including a full range carrying FDA and EU food contact approvals. With its resistance to alkaline cleaning products and high temperature steam cleaning, PEEK is a popular choice for food processing machinery applications. Bieglo offers self-lubricating versions for bearings and gears, as well as coloured and detectable grades. The company can also offer PPSU options for food processing. These grades are translucent, sterilisable and can withstand continuous operat- ing temperatures of up to 160°C. �

Below: Recycled polyolefins from MTM Plastics feature among the Borealis display
Borealis will be exhibiting together with sister companies Borouge and Nova Chemicals at K2019, where the emphasis will be on it efforts to develop more sustainable “circular” products. These include its move into mechanical recycling through its investments in MTM Plastics and Ecoplast. The show will see the launch of the company’s
Borcycle technology for reprocessing waste polyolefin to high quality plastic compounds. The first commercial example is Borcycle MF1981SY, which is developed for production of visible black
B :
appliance parts and contains 80% recycled content. The 10% talc-filled grade is said to provide a good balance of stiffness and impact resistance while offering a 30% reduction in CO2
emissions compared to
a virgin equivalent. Borealis will also introduce improved versions of its Purpolen recycled grades.
Purpolen PP Y40 is a recycled PP with a MFR of 40 suitable for produc- tion of pails, thin wall packaging and appliance parts; Purpolen PE FF is a fine-
filtered PE with a low gel level; and Purpolen PE Y01 is a 100% post-consumer recycled grade with a low MFR suitable for pipe and large bottle production. �

Brüggemann will present its full range of additives for enhancing the performance of polyamide resins, including new flow enhancers and heat stabilisers as well as products specifically formu- lated for “upcycling” recycled resins. Flow enhancing products include Brügge-
mann TP-P1810, which the company claims is the first additive of its type that shows a significant flow improvement with polyphthalamide (PPA) resins, such as PA6T, PA6T/6I and PA6T/66, without compromising mechanical property characteristics. The ability to significantly widen the processing window makes it possible to process compounds with fibre contents of up to 60%, the company claims. The additive will be displayed alongside the company’s TP-P1507 grade, which was intro- duced at the previous K fair for use with aliphatic polyamides such as PA6, PA66 and PA12. Three new heat stabilisers will be introduced at
K2019.Phenolic Plus TP-H1803 is said to fill the price/performance gap between current phenolic and copper-based stabiliser blends, extending the temperature range to peaks of 180°C. Brug- golenTP-H1607is a copper iodide-based stabiliser that can provide long term performance at up to 180˚C at low addition levels. Bruggolen TP-H1805 is formulated to stabilise fibre-reinforced aliphatic polyamides for long-term application at tempera- tures up to 200°C for PA6 or up 230°C for PA66 without separate activation. The company says the new product will allow PA compounders to produce grades suitable for applications currently served by PPA or PPS materials. In the recycling area, Brüggemann will introduce two new reactive chain modifiers, which allow
