High definition Flexible Fiberglass Sheets - FR4 Rigid Epoxy Glassfiber Laminated Sheet – Xinxing Detail:

Product Description

This product was laminated by the high temperature and high pressure with electronic glassfiber cloth impregnated with brominated epoxy resin.It with high mechanical properties,dielectric properties and flame retardant properties,it also with good heat resistance and moisture resistance;

FR-4 is a code of a grade of flame-resistant materials, which means a material specification that a resin material must be able to extinguish by itself after burning. It is not a material name, but a material grade. The name FR4 comes from the NEMA grading system where the ‘FR’ stands for ‘fire retardant’, compliant with the UL94V-0 standard. Therefore, general PCB circuit boards, There are many types of FR-4 grade materials used, but most of them are composite materials made of Tera-Function epoxy resin with filler and glass fiber.

Compliance With Standards

In accordance with GB/T 1303.4-2009 electrical thermosetting resin industrial hard laminates – Part 4: epoxy resin hard laminates, IEC 60893-3-2-2011 insulating materials – electrical thermosetting resin industrial hard laminates – Part 3-2 of the individual material specification EPGC202.
