Description

3242 Epoxy Glass Cloth Laminate

3242 epoxy glass cloth laminate is an upgraded, higher-temperature version of the classic epoxy glass family, manufactured by hot-pressing epoxy-impregnated E-glass cloth into rigid boards rated for Class F (155 °C) service.

It delivers dielectric strength of at least 15 kV/mm and flexural strength ≥340 MPa, with excellent dimensional stability under combined heat and mechanical stress. These properties make 3242 a preferred insulation material for high-temperature transformers, Class F motors and switchgear.

Available from 0.5 mm to 50 mm thick as sheets or CNC-cut parts, our 3242 ships factory-direct to the USA, Mexico, Brazil and Europe.
