SmithLamina FR4 glass epoxy laminates are continuous filament woven fiberglass sheets bonded with flame resistant epoxy resin. The material has the ability to maintain excellent mechanical, electrical, and physical properties at elevated temperature to 130�C.

FR-4 epoxy resin systems typically employ bromine, a halogen or halogen free, to facilitate flame-resistant properties in FR-4 glass epoxy laminates.

FR-4 glass epoxy is a popular and versatile high-pressure thermoset plastic laminate grade with good strength to weight ratios. With near zero water absorption, FR-4 is most commonly used as an electrical insulator possessing considerable mechanical strength. The material is known to retain its high mechanical values and electrical insulating qualities in both dry and humid conditions. These attributes, along with good fabrication characteristics, lend utility to this grade for a wide variety of electrical and mechanical applications.
