Products Description
Glass Polyester Laminated Sheet is made of alkali-free glass fiber cloth impregnated with unsaturated polyester resin and laminated under high temperature and high pressure. It has high mechanical strength, arc resistance, high temperature resistance and other characteristics, and is widely used in insulating structural parts of electrical equipment.
Glass Polyester Laminated Sheet Key parameters (according to IEC 60893 standard):
Heat resistance level: long-term temperature resistance of 155℃ (F grade)
Dielectric strength: ≥30kV/mm (1 minute withstand voltage test)
Density: 1.7~1.9g/cm³
Flexural strength: ≥300MPa (ASTM D790)
Nominal size: 1000×2000mm; 1010×2020mm; 1250×2500mm
Nominal thickness: 0.8～60mm
Note: Special specifications can be negotiated between the supplier and the buyer.
