In these applications, Tecodur ECO PBT – which includes recycled PET from consum- er bottles – can be used to reduce material footprint with high mechanical properties and good UV resistance.

Antenna design Kraiburg TPE has developed a new thermoplastic elastomer that it says can improve the design of automotive antennas. Its Thermolast R RC/UV/AP materials boast a


range of advantages that claim to “redefine automotive antenna performance”. For one, it incorporates 15-40% recycled raw

materials, aligning with sustainability goals. At the same time, it shows high adhesion to PP, for seamless integration, is low density (allowing lightweight design without compromising durabil- ity) and has a temperature stability up to 90°C, for reliable performance in various conditions. Other benefits include: superior weather


resistance; enabling of recycling-specific raw material influences for enhanced sustainability; using injection moulding for efficient and cost- effective manufacturing; and availability in black for


IATF 16949:2016 certification for automotive quality. This, it says, confirms its ability to respond to the


increasingly stringent requirements of the automo- tive market. IATF 16949:2016 enables Lati to guarantee high quality standards in its processes and products for the automotive sector. It says the combination of the IATF certification and its technical expertise in the electrical and electronics sectors will open up opportunities in the electric vehicle market. “This certification will allow us to more effectively present our solutions in the automotive sector, creating new growth opportunities,” said Vittorio Gerola, group general manager business at Lati.


Recycled TPVs Teknor Apex has developed a new series of Sarlink thermoplastic vulcanizates (TPVs) with up to 40% recycled content. Its Sarlink RX 3100B TPVs contain post-industrial recycled (PIR) content, to ensure high processability and performance. The series was developed to help automotive


brands achieve sustainability targets, by incorpo- rating up to 40% PIR, depending on the hardness. The grades can be processed in multiple ways, including injection moulding and overmoulding. The two grades – an 84 Shore A and 94 Shore A


– are based on the existing Sarlink 3100 technology, but contain 25% and 40% recycled content, respec- tively. The materials behave similarly to their virgin counterparts but with sustainability benefits, such as a reduced amount if virgin material – which could help OEMs increase sustainable material content in vehicles. Sarlink RX 3100B TPVs are pre-coloured black and can themselves be recycled. Using PIR – rather than post-consumer recyclate
