Glass for electrical insulation - gpo3 fr4 fr5 g5 g7 g11

The vetronites may contain epoxy, polyester, melamine and silicone resins with different thermal class depending on the model chosen. They have excellent mechanical and dielectric characteristics and are suitable for use in many sectors and are the excellence for the electromechanical sector. It should be noted that FR4, GPO3 and FR5 glass elements are self-extinguishing according to the UL 94 V0 standard. The GPO3 and FR5 material are also non-marking and halogen-free. The GPO3 material is a layered insulation based on glass mat and filled polyester resin and is used for machined and sheared pieces. It has good mechanical properties and is suitable for blanking up to 6mm thick. It has good dielectric properties. The FR4, G11 and FR5 laminates are layered with a glass fabric and epoxy resin base. They have different thermal classes. LG11 material exists in two versions: - Insulation class F (155 ° C), code LG11 - Insulation class H (180 ° C), code LG11H
