GPO3 Polyester glass mat sheets Your location:home > Products

  Grade GPO3 sheet is made with unsaturated polyester resin containing glass reinforcement,usually mat of randomly laid glass fibers,and suitable fillers,GPO3 is cured by heat and pressure,the resin system is flame resistant.
  GPO3 sheets has good mechanical strength,dielectric strength,and excellent arc and carbon tracking resistance,grade GPO3 is flame resistant.it is designed for general purpose insulation and mechanical support in electrical equipment,where a flame resistant material is required.
Performances and Applications of GPO3 sheet:
  1. High mechanical strength, mechanical applications and impact resistance.
  2. Can be easily processed by standard mechanical processing equipments.
  3. Available for punching, drilling, mechanical processing, and shearing.
  4. Stable size and small tolerance in thickness, could meet tolerance requirements without granding.
  5. Good electrical performance in high humidity, CTI >300V, good arc resistance(>150 seconds), excellent heat resistance, distortion temperature>240℃, Grade F hear resistance, flame resistance, America UL94 V-0 rating standard, no halogen, less smoke on fire, various types and specifications.
  6. Groove shape, horn, square tubes, square sticks, pipe, round rods.
  7. Available in medium and high voltage inverter, converter, high-voltage switchgear service such as main insulation materials.
  8. Used as pillar, beams, cable trough etc.
  9. Breaker safety baffle, safety cover board, interval liner, alternate with clapboard, arc plate of arcing chamber etc.
  10. Motor armature components and self-sealing cover-plate, slot wedge stator, calm gaskets, thin gasket, carbon brush stands, and so on.
  11. The front-end switchgear, and back-end, top and bottom, alternate with clapboard, etc.
  12. Structural parts for arc resistance and insulation support pieces.
