FR4 Epoxy Fiber Glass Sheet
FR4 Epoxy Fiber Glass Sheet is a thermosetting laminate plastic. FR4 Sheets are made of multiple layers of electrical fiberglass cloth impregnated with epoxy resin and heat pressed under high temperature and pressure. This kind of composite material is highly distinguished by its impressive mechanical strength and dielectric properties. FR4 is flame retardant UL94-V0. TG:266F±41F（130±5℃） It is manufactured in flat sheets.Thickness ranges from 0.01″(0.3mm) to 4″(100mm), and available size in 12″x 12″, 24″x24″, 48″x 80″,48″x 48″and 48″x 96″. All of our FR4 sheets come with a protective film to avoid scratches during handling and transport.

FAQ
Is G-10 different from FR-4?
G10 composite materials on the same properties as FR4, but FR4 is flame retardant, and it has a UL flammability rating of 94 V-0. The FR 4 material can usually be used where G10 material is specified, however, G10 Laminate should not be used where FR-4 is specified.
What is FR4 made of?
FR4 is a printed circuit board substrate made of laminating flame-retardant epoxy resin and glass fiber cloth. FR stands for this material is flame retardant and meets UL94V-0 requirements.
Does FR4 contain bromide?
Yes, FR4 contains bromides because of the addition of flame retardant inorganics. Ask our plastics experts for bromide-free.
