K2022 PREVIEW | MATERIALS
Above: HPF will show its mineral filler-based odour absorb- ers for use with post consumer recycled plastics
DuPont will show its Hytrel Eco B range of bio- based (mass balance) TPC-ET thermoplastic elastomers in Dusseldorf. Eco B grades are claimed to deliver performance equivalent to regular grades but carry an attributed biomass content up to 72% by weight. The biomass content of Hytrel Eco B grades is
certified by the ISCC Plus standard. The material uses attributed feedstocks derived from second- generation bio residue or waste streams that do compete with food/feed resources. The company will also show its latest technology advance allowing production of Zytel HTN over- moulded busbars for high voltage and power appli- cation in electric vehicles. DuPont has fine-tuned an overmoulding support package that combines supply of Zytel HTN resins along with the required technical analysis tools and processing support. �

increasingly important, the use of high-quality plastic recyclates in new products is demanded wherever possible. However, contaminated post-consumer or post-industrial plastic waste represents a challenge as the required level of quality often cannot be achieved. The odour profile of recyclates, in particular, often causes dissatisfac- tion, with impurities or the recycling process itself causing unpleasant odours. HPF has formulated a range of mine-
ral-based odour absorbers. Olfato- metric tests have shown that, when blended into a post-consumer PP recyclate at a level of 5% in a twin-screw extruder,

the resulting compounds present an odour intensity significantly below the threshold set in the VDA 270 automotive standard. The company will also display a number of polymer parts produced using its Silatherm mineral additives, which can be used in compounds to enhance thermal conductivity. Heat generation and dissipation is becoming an important considera- tion in areas such as automotive, says the company, where electronics are becoming increasingly widely used. Silatherm additives can be used to improve thermal conductivity without negatively impacting electrical properties. With a variety of surface treatment options available, good mechanical properties and processing characteristics can be maintained, the company says. �

Ineos Styrolution will be showing a number of sustainable additions to its range at K2022, includ- ing its Luran S ECO range of ASA compounds with 50% bio-attributed content (mass balance). Luran S is particularly known for use in outdoor
applications, where its UV resistance makes it a good choice for the toy, sport and leisure indus- tries. The ECO grades offer the same UV resistance together with a 58% carbon footprint reduction, depending on the specific grade, it says. The company will also show its first SBC prod-
ucts produced from 100% bio-attributed feedstock. The new materials are available in its Styrolux and Styroflex product lines. Both the styrene and butadiene components are derived from bio-attrib- uted feedstock, such as kitchen and food waste. The result is a material with a neutral or negative carbon footprint, the company says. Like conventional Styrolux and Styroflex grades,
the bio-attributed products provide a good combination of transparency, brilliance, and impact resistance. Ineos Styrolution says Styrolux resin is a good choice for applications such as labelling and twist films, food packaging, and medical applica- tions; Styroflex is a thermoplastic elastomer (S-TPE) that can be used in wrap films, stretch hoods and as a modifier.
