NEMA Grade FR4 materials are glass fabric reinforced laminates, bonded with frame resistant epoxy resin.
The material has the ability to maintain excellent mechanical, electrical and physical properties at elevated
temperature to 130°C.
We provide a wide range of material solutions from rigid, glass epoxy composites to high-temperature
This model provides application-specific solutions, shorter lead times, and materials that meet or exceed our customers’ most demanding application requirements.
