development
tion of electronic parts, by combining the three conventional steps of pre-heating, thermoforming and functional integration into a single process, resulting in lower costs and shorter cycle times. DSM has started a new production line for Arnitel in Emmen, the Netherlands. The capacity will be expanded by 20% and will enable greater supply flexibility and security. The new production line will allow DSM to meet growing demand for Arnitel high performance thermoplastic copolyes- ters (TPCs). The company says these materials combine elasticity, high temperature resistance and mechanical properties, as well as good processing characteristics, and have a number of E&E applications. DSM has also expanded its electric vehicle thermal management range with a new PPS grade. Xytron G4080HR is a 40% glass-reinforced PPS engineered for heat ageing performance, hydroly- sis resistance, dimensional stability, chemical resistance at elevated temperatures and intrinsic flame retardancy. “As our customers work to
enhance the performance of electric vehicles through lightweighting, it is essential for us to design lightweight materials able to withstand the increased heat and prolonged chemical exposure requirements of EV thermal management systems,” says Lu Zhang, global business line director, DSM Engineering Plastics. The company says that because Xytron G4080HR is specifically formulated for typical EV thermal management system lifecycles, it maintains its strength at continuous operating temperatures exceeding 130°C for 6,000-10,000 hours. In a recent 3,000 hour, 135°C water-glycol fluid test versus a comparable competitor grade, Xytron G4080HR delivered 114% higher tensile strength and 63% higher elongation at break. The combina- tion of resistance to heat, moisture and chemicals provide electrical and electronic applications in connectors, structural parts, e-motors, bobbins, switches and sensors. PolyOne has developed new polymer formula- tions for 5G telecommunications network develop- ment. The company says that these advanced materials will help increase speed to market and design flexibility for 5G base station antenna manufacturers. New customisable Edgetek Formulations for 5G feature specific Dk values and reduced dissipation factors (Df), enabling faster design qualification and shorter lead times. Another new formulation within this product family is compatible with SMT (surface mount technol- ogy), allowing greater design flexibility and increased speed to market for 3D circuit boards. Both materials can help 5G base station antenna manufacturers to streamline their design and process development. 5G networks are forecast to bring notable benefits to the mobile phone and tablet user, and are also expected to have a major effect on emerging systems such as smart cities, AI devices,
