Graphite Filled Teflon PTFE Gland Packing

Description

Graphite-filled Teflon PTFE gland packing is a braided packing material that combines the chemical resistance of PTFE with the high-temperature resistance of graphite. It’s used in pumps, valves, mixers, and other rotating equipment. 

How it works

• The graphite in the packing is integrated into the yarn, so it stays smooth when rubbed. 
• The packing is self-lubricating and absorbs abrasive particles. 
• The graphite improves the packing’s thermal conductivity, which is useful for sealing tubes in high-speed pumps. 

Where it’s used 

• Chemical and pharmaceutical industries: Used to seal hostile chemical systems, acids, and bases
• Food processing industry: Used in food processing plants
• Oil and gas industry: Used in petroleum refining plants
• Power supply industry: Used in chemical services

Properties 

Chemical resistant, Heat resistant, Wear resistant, Self-lubricating, Absorbs abrasive particles, Versatile, and Small shrinkage

Graphite-filled PTFE gland packing has many properties, including:

• Chemical resistance: PTFE is chemically inert and resistant to most hydraulic fluids. Graphite is also resistant to corrosion. 
• Thermal conductivity: Graphite improves the thermal conductivity of PTFE, making it ideal for high-temperature applications. 
• Low friction: Graphite-filled PTFE has a low coefficient of friction, which reduces energy consumption and wear. 
• Wear resistance: Graphite-filled PTFE has excellent wear resistance and can handle high loads in high-speed applications. 
• High pressure: Graphite improves the packing’s ability to handle higher pressures. 
• Extrusion resistance: Graphite-filled PTFE has excellent extrusion resistance. 
• Self-lubricating: Graphite-filled PTFE can be self-lubricating. 
• Absorbs abrasive particles: Graphite-filled PTFE can absorb abrasive particles. 

Graphite-filled PTFE gland packing is used in a variety of applications, including: 

• Pumps
• Mixers
• Stirrers
• Chemical processing
• Power generation
• Hydraulic/pneumatic compression type rod and piston seals
• Bearing bands
• Rotary applications
