Introduction
Epoxy glass cloth laminate materials are the most versatile and fast growing area in laminated material industry.
They come with higher mechanical strength and electrical performance than phenolic cloth and paper laminates. Especially, the epoxy glass laminate features excellent resistance to moisture and high temperature. Therefore, it finds quite wide applications from power generation to medical instruments, from electronics to aerospace, and from oil transportation to mining.
The F880 series epoxy glass cloth laminated sheets from we are developed to the NEMA standard and boast the product performances under that standard.
