Description
NEMA FR4 is a high-performance laminate composed of continuous woven glass fabric impregnated with an epoxy resin binder. These materials are commonly found in shades of yellowish to light green and are highly versatile, making them ideal for a wide range of applications, including electrical insulation, aerospace, marine and automotive industries.
Epoxy resins are highly valued in the electronics and electrical industries due to their minimal water absorption, making them exceptional electrical insulators. Additionally, they offer remarkable dimensional stability and strong adhesive properties. NEMA FR4 laminates exhibit outstanding mechanical strength, low dielectric loss and high electrical insulation performance making them preferable for high-performance engineering solutions.
