⩟ With high thermal conductivity, up to 220W/(℃*m), small thermal expansion coefficient, only around 4*10-6/℃, thermal shock resistance is good.
⩟ Good electric insulation, high breakdown voltage, large current carrying capacity.
⩟ High mechanical strength, good toughness, strong resistance to mechanical impact.
⩟ It can resist erosion of various acid, alkali and other chemical substances, corrosion resistance is very good.
⩟ Low dielectric constant and dielectric loss can reduce the energy loss during signal transmission.
