Industry Leading, Standard Loss, Thermally Robust Epoxy Laminate and Prepreg

  isola 370hr is the industry's “best in class” lead-free compatible product for high-reliability applications across a wide range of markets.

  isola 370hr laminates and prepregs, deigned by Polyclad, are made using a patented high performance 180°C Tg FR-4 multifunctional epoxy resin system that is designed for multilayer Printed Wiring Board (PWB) applications where maximum thermal performance and reliability are required. isola manufacture isola 370hr laminates and prepregs with high quality E-glass glass fabric for superior Conductive Anodic Filament (CAF) resistance.  isola 370hr provides superior thermal performance with low Coefficient of Thermal Expansion (CTE) and the mechanical, chemical and moisture resistance properties that equal or exceed the performance of traditional FR-4 materials.

  isola 370hr is used in thousands of PWB designs and has proven to be best in class for thermal reliability, CAF performance, ease of processing and proven performance on sequential lamination designs.
