Polyester glass mat sheet Your location:home > Products

  Polyester glass mat sheet is made with unsaturated polyester resin containing glass reinforcement,usually mat of randomly laid glass fibers,and suitable fillers.
  Grade GPO1 is cured by heat and pressure.the material has good mechanical strength and arc resistance,it is suited for general-purpose electrical equipment applications requiring good dielectric properties.grade GPO1 is not flame resistant.GPO2 is designed for general purpose insulation and mechanical support in electrical equipment.
  Grade GPO2 is cured by heat and pressure.the resin system is flame resistant.the material has good mechanical strength,dielectric strength,and arc resistance,GPO2 is flame resistant.GPO2 is designed for general purpose insulation and mechanical support in electrical equipment,where a flame resistant material is required.
  GPO3 is cured by heat and pressure.the resin system is flame resistant.the material has good mechanical strength,dielectric strength,and excellent arc and carbon tracking resistance,GPO2 is flame resistant.GPO3 is designed for general purpose insulation and mechanical support in electrical equipment,where a flame resistant material is required.
