Melamine glass cloth laminated sheet is made from a continuous filament woven giass fabric with a melamine resin binder,the melamine resin system is flame and arc resistant. The melamine resin system is flame retardant and arc resistant.Melamine sheet can be processed into all kinds of insulation parts, The products are widely used transformers, electric motors, cabinets, control boxes, electric switches, household appliances, railway, automobile, computer and medical appliance,etc.
Grade G-5 exhibits high mechanical strength at room temperature and is one of the hardest
laminate grades.Fair dielectric loss and electric strength properties under dry conditions. Excellent arc rasistance. Meets UL 94 V-O.
Grade G-5 is flame and arc resistant. It is designed for mechanical support in electrical equipment applications.
Grade G-9 Sheets-High mechanical strength(flexural and impact) at room temperature. Fair dielectric loss and electric strength properties under dry condrtions. Excellent arc resistance. Meets UL 94 V-O.
Grade G-9 is flame and arc resistant.it is designed for mechanical support in electrical equipment applications. The laminate should not be used where the continuous electric stress exceeds the volts per mil of thickness.
