Astra MT77 is Isola's ultra-low-loss thermoset material designed specifically for 77 GHz automotive radar and other millimeter-wave applications. With Dk 3.00 and Df 0.0017 at 10 GHz, it delivers near-PTFE performance without PTFE processing headaches. Temperature stability from -40°C to +140°C covers automotive requirements. Unlike RT/duroid and other PTFE materials, Astra MT77 requires no plasma decontamination or sodium naphthalene treatment. This simplifies fabrication and reduces cost for automotive radar modules including adaptive cruise control, pre-crash sensing, and blind-spot detection. Consider Astra MT77 when you need 77 GHz performance but want to avoid PTFE processing complexity.
