Uchungechunge lwe-EPGC I-Epoxy Glass Cloth Rigid Laminated Sheet liqukethe indwangu yengilazi elukiwe efakwe i-epoxy thermoseting resin, elamine ngaphansi kwezinga lokushisa eliphezulu nokucindezela okukhulu. Indwangu yengilazi elukiwe ngeke ingabi ne-alkali futhi iphathwe nge-silane coupler. Amashidi ochungechunge e-EPGC ahlanganisa i-EPGC201 (NMEMA G10), EPGC202( NEMA FR4), EPGC203(NEMA G11), EPGC204 (NEMA FR5), EPGC306 kanye ne-EPGC308.
