SYNTHETIC FIBER GLAND PACKING
Synthetic Fiber Gland Packing is a high-performance compression sealing material manufactured from engineered synthetic fibers and braided into square or specialized cross-sectional structures. Compared with traditional natural fiber packing, synthetic fiber packing provides improved mechanical strength, chemical resistance, wear resistance, and thermal stability.
Depending on the operating requirements, synthetic gland packings may be produced using materials such as acrylic fiber, aramid fiber, PTFE fiber, PAN fiber, carbon fiber blends, and other advanced synthetic compounds, often combined with lubricants and special impregnation treatments.
Synthetic Fiber Gland Packing is widely applied in pumps, valves, mixers, agitators, marine equipment, chemical plants, and industrial process systems.

DIFFERENT TYPES OF SYNTHETIC FIBER GLAND PACKING
PTFE with Kynol Fiber Corners Packing, Acrylic Fiber Packing, Acrylic Fiber Treated With Graphite Packing, PAN Fiber Packing, PAN Fiber Packing Treated With Graphite, Kynol Fiber Packing:
PTFE with Kynol Fiber Corners Packing
Braided from KynolTM fiber and PTFE fiber. It contains the advantage both PTFE and kynol. It has good strength and lubricates.
Acrylic Fiber Packing
Acrylic fiber packing braided from high strength acrylic fiber with PTFE impregnated twice time. It has excellent properties of sealing, lubricating and resistant to chemical. The acrylic packing can be with or without oil. High elastic red silicone rubber core can absorb vibration.
Acrylic Fiber Treated With Graphite Packing
Braided from high strength acrylic fiber treated with graphite and special lubrication. The graphite increased the temperature and excellent lubricated.
PAN Fiber Packing
Braided from high strength PAN fiber pre-impregnated with PTFE and special lubrication. Re-impregnated during square moulding. It has excellent properties, lubricating and resistance to chemicals.
PAN Fiber Packing Treated With Graphite
Treated braid from high strength PAN fiber and graphite, impregnated with special lubrication. Graphite filler increases the service temperature and density of the packing.
Kynol Fiber Packing
Braided from high-performance KynolTM ( NovilidTM or PhenolicTM) fiber impregnated with PTFE lubricant, good mechanical properties combining softness and strength.
