Insulating ceramics ring characteristics: the product uniformity good, small loss at high frequency, insulation performance is strong, dielectric constant is small, high mechanical strength, good air-tightness, thermal stability, chemistry stability is good.

High wear resistance, high strength, wear low, long service life, no pollution to the material

Special ceramics with high intensity, high temperature resistance, corrosion resistance, wear resistance, high insulation of metal and plastic incomparable characteristics.
