Injection Moulding

Injection Moulding Injection moulding grade PLA UK based bioplastics technology company Floreon has developed a new range of PLA based compounds for the injection moulding of durable products. Floreon’s formulations enhance PLA, making it ten times tougher than standard unmodified PLA. Floreon’s high performing bioplastic technology offers an up to 83 % lower carbon footprint than ABS, making it a commercially viable renewable alternative to such traditional plastics. Last year, Floreon has reached a period of accelerated commercialisation which has led to gripping new projects and welcomed additions to the team. Led by customer demand, Floreon can now offer high impact and flame retarded materials which retain a renewable carbon content of 85 % and above. The new grades have impact strength comparable to certain ABS grades and can achieve a UL94V-0 rating for fire resistance over a range of thicknesses. The target applications for these materials include consumer electronics and automotive parts, where first customers are now launching products on the market. This is a significant development for bioplastics as, until now, unmodified PLA lacks the impact strength needed for many durable applications and the inclusion of a flame retardant can cause degradation during processing, something Floreon has been able to overcome. Floreon was founded by serial entrepreneur, Shaun Chatterton, who remains at the commercial forefront of the company as well as having several highly respected HNW investors helping to realise the global potential of Floreon’s technology. The development has been closely supported by Floreon’s collaborative partner Clariant, that has assisted in testing and the provision of additives, to help Floreon meet customers’ performance criteria. “Converting bioplastics into mainstream durable solutions has long been limited, among others, by the lack of suitable high-performance additives. We have taken on this challenge and have been developing new integrated solutions, together with Floreon,” says Nicola Lelli, Head of Global Marketing, BU Additives at Clariant. 2020 ICIS Innovation award-winning Licocare ® RBW Vita, for example, are highperformance additives for bioplastics based on renewable crude rice bran wax. This additives range has also been awarded the OK compost INDUSTRIAL certificate. Beyond the collaboration with Clariant and due to the Coronavirus pandemic, Floreon has also tested an off-the-shelf antimicrobial additive with the new durable grades and found it to be highly effective in preventing the growth of both Grampositive and Gram-negative bacteria. Whilst no claims can yet be made regarding activity against COVID-19, this is anticipated in the not-too-distant future and Floreon are looking forward to making this positive contribution. The team at Floreon believe in the sustainability benefits of using enhanced PLA over oil-based plastics and remain open to new collaborations. AT | 18 bioplastics MAGAZINE [02/21] Vol. 16

Partially biobased transparent PA Evonik (Essen/Marl, Germany) is adding a sustainable, high-performance moulding compound to its range of transparent polyamides. Trogamid ® myCX eCO is produced to 40 % from a biobased monomer and entirely with renewable energy. This results in a 50 % reduction in the CO 2 footprint compared to the qualitatively equivalent premium product produced on a petrochemical basis using conventional energy sources. Sustainable and high quality Trogamid myCX eCO is a high-purity microcrystalline highperformance polyamide specially optimized for the optics industry for products such as lenses, by injection moulding. The name eCO stands for eliminate CO 2 . On the one hand, this is achieved by replacing a petrochemical-based raw material with a biobased one. By mass balance (see also article on pp 54), this results in 40 % biobased raw material in the polymer. Secondly, only renewable energy is used in the production of the granules. This and the resulting halving of the carbon balance compared with the fossil-based product are confirmed by a certification from TÜV Rheinland. The analysis was prepared in accordance with ISO 14040 and ISO 14044, and includes the Cradle-to-Gate stage. The sustainable manufacturing process in no way alters the outstanding properties of Trogamid myCX, which is wellknown on the market, such as its excellent transparency of over 90 % – the crystallites of the material are so small that they do not scatter visible light. Thus, the product appears transparent to the human eye. The microcrystalline structure gives this polymer outstanding mechanical properties, stress cracking resistance, and break resistance. Trogamid myCX eCO thus also ensures long durability and high safety of premium lenses or high-quality visors for ski and snowboard goggles, as well as excellent wearing comfort due to its low weight. Customized plastic materials Trogamid stands for a product family of transparent polyamides that have been successfully used in the optical industry for over 20 years. The portfolio includes innovative high-performance plastics for lenses and frames as well as other materials, for example for UV protection or pole films for high-contrast vision.
