WebFR4 material is a glass-reinforced epoxy laminate commonly used in applications requiring high stiffness and rigidity, such as printed circuit boards (PCBs). It is generally available in two forms: as a solid core laminate or as a multilayer laminate. In either form, it’s a fire-resistant material used to create high-quality PCBs. http://frontlinefireprotection.com/Testing.html
