DSM has expanded its PIN flame retardant range of high-temperature resistant bio-based polymers with new ForTiiEco 4T nylon grades, using up to 30% renewable resources based on castor beans. The compounds offer high-flow processing, mechanical robustness, high-temperature soldering resistance, stable dielectric constant and loss tangent.
Applications target high performance and thin-wall electronics, including surface-mount technology (SMT) connectors (such as the new micro USBs), antennas, RFID (Rapid Frequency Identification) security casings and switches for mobile devices. The LDS62 grade in particular offers the technology to incorporate fine electronics circuitry by laser direct structuring (LDS). Today, DSM’s entire plastics portfolio for the electronics market is non halogenated.
