WebbGrade designations for glass epoxy laminates that Vanderveer Industrial Plastics deals in are: G10, G11, and FR4. Of these, FR4 is the grade most widely in use today. G-10, the predecessor to FR-4, lacks FR-4's self-extinguishing flammability characteristics and for all intents and purposes is distributed by Vanderveer Industrial Plastics as G10/FR4. Thermosetting plastics are generally stronger than thermoplastic materials due to the three-dimensional network of bonds (crosslinking), and are also better suited to high-temperature applications up to the decomposition temperature since they keep their shape as strong covalent bonds between polymer chains cannot be broken easily. The higher the crosslink density and aromatic content of a thermoset polymer, the higher the resistance to heat degradation and che…
