  • Asbestos Joint sheet
    Asbestos Joint sheet with low density, high performance gasket material designed for elevated temperature applications. It is composed of a blend of asbestos fibre, inorganic fillers nitrile binder. This provides the material with good torque retentions when combined with a metal core. It's low density makes it ideally suitable for perforated core applications & the high compressibility imparts go
  • PTFE sheet
    PTFE gasket sheetMATERIAL:100% ptfe resin TEMPERATURE LIMIT:-180-250 PRESSURE LIMIT:20Mpa MAIN APPLICATIONS:processing spacers and irregular parts used for sealing, insulation,and antisepsis SURFACE:
  • Carbon Fiber Packing
    Carbon Fiber Packing
    The carbonized fiber yarn is treated with graphite particles, and then is braided to form packing. Its surface is coated with a high-temperature-proof lubricant. It is able to bear high temperature and pressure, and helps prevent abrasion and also help to minimize the effects of electrolytic pitting of the valve stem.
  • Expanded Graphite Braided Packing
    Materials: Expanded graphite yarn
    Temperature:450 degree (in oxidized atmosphere) 850 degree(in non-oxidized atmosphere)
    Pressure:25.0mpa
    Main uses: It is widely used in the steam valves of power plant, or as static sealing
    In places where high temperature and pressure, or chemical corrosion prevails.
