Epoxy glass cloth laminated sheet Your location:home > Products

  Epoxy glass cloth laminated sheets(insulation sheet,industry laminate sheet,Epoxy sheet) are made of alkali-free E-glass cloth impregnated with epoxy resins and phenolic resins by processing under heat and pressure. Epoxy glass cloth 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 G10 sheets exhibits extremely hight mechanical strengths(flexural,impact,and bonding) at room temperature,good dielectric loss and electric strength properties under both dry and humid conditions.
  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.
  Grade G11 sheet exhibits extremely high mechanical strengths(flexural,impact) at room temperature,and maintains a minimum of 30.0 ksi flexural strength at 150℃,good dielectric loss and electric strength properties under both dry and humid conditions.
  Grade FR5 sheet exhibits good chemical resistance and its heat resistance is better than FR-4,material is intended for use as electrical and electronic insulation whrer low moisture absorption and high physical strength is needed,it is not recommended for wear applications.
