EPGM203 Epoxy Glass Mat Laminate

Product features: EPGM203 epoxy glass mat laminate is made of alkali-free glass mat impregnated with epoxy resin by hot pressing. It is an F-class epoxy glass mat laminate produced according to the requirements of the IEC60893-3-2 "Specification for Industrial Rigid Laminates of Thermosetting Resin for Electrical Use". It has the characteristics of high mechanical strength at medium temperature, good electrical performance stability at high humidity, and high parallel layer breakdown voltage. Application areas: EPGM203 epoxy glass mat laminate is suitable for Class F motors, electrical equipment as insulating structural parts and other purposes. Thickness range: 0.2mm--100mm Main dimensions: 1500mm * 3000mm, 1220mm * 3000mm, 1020mm * 3000mm, 1020mm * 2440mm, 1220mm * 2440mm, 1500mm * 2440mm, 1000mm * 2000mm, 1200mm * 2000mm and other sizes based on the agreement between the supply and demand sides.
