Epoxy Glass Cloth FR4 Sheet ,Grade FR4 Sheet exhibits extremely high mechanical strength(flexural,impact,and bonding) at room temperature and has good dielectric loss and electric strength properties under both dry and humid conditions.Light Green FR4 Sheet are electrical alkali-free glass woven fabric base impregnated epoxy resin binder by processing under pressure and heat, which have extremely high mechanical strength, good dielectric properties, good electric strength properties and fine heat and humidity resistance. In addition, it has anti-fire property.
Grade FR4 sheet exhibits good chemical resistance and its heat resistance is better than FR-4,material is intended for use as electrical and electronic insulation where low moisture absorption and high physical strength is needed,it is not recommended for wear applications.
Epoxies are thermosetting polymer resins where the resin molecule contains one or more epoxide groups. The chemistry can be adjusted to perfect the molecular weight or viscosity as required by the end use. Their are two primary types of epoxies, glycidyl epoxy and non-glycidyl. Glycidyl epoxy resins can be further defined as either glycidyl-amine, glycidyl-ester, or glycidyl ether. Non-gylcidyl epoxy resins are either aliphatic or cyloaliphatic resins.
