Lightweight products-hard back plate(ZTT-CHC)

To improve the impact resistance of lightweight components, the hard black plate products are introduced. Synergetic work of the laminated reinforcement materials and the resin coating corresponding to the characteristic groups realizes perfect mechanical property, electrical insulation property and  excellent weather resistance, and excellent product performance after different aging has been achieved.

Product  Details
  • High strength, impact resistance: glass fiber content reaches 60%,good mechanical property
  • Good insulation: glass fiber base material has good electrical insulation performance,insulation and voltage resistance
  • Excellent weather resistance: good performance after various agings
