FR-4 / FR-5 Epoxy Glass Sheet
Flame-retardant epoxy glass sheet for electrical insulation structures, higher thermal reliability and demanding industrial environments.
Product Description
FR-4 and FR-5 epoxy glass sheets are designed for buyers who require flame-retardant performance together with strong mechanical and electrical properties. FR-4 is the well-known mainstream grade, while FR-5 is selected when higher heat resistance and long-term thermal stability are needed.
