Garlock GYLON 3504 (Blue Sheet)

A high performance gasket sheet of PTFE with an aluminosilicate microsphere filler.  Widely used in glass-lined flanges and other light duty flanges where available torque is limited.

Garlock GYLON® gasketing is a family of flat PTFE gasketing materials. GYLON® high-performance PTFE gasketing is manufactured using a proprietary process that imparts unique physical properties, which are not obtainable through conventional manufacturing methods: Designed for severe chemical service, color-coded for easy identification, superior sealability, which helps reduce process and media loss as well as fugitive emissions, reduced creep and cold flow characteristics, and patented thermal bonding process to fabricate virtually any size gasket. The innovative GYLON® gasketing process reorients the PTFE and fillers in such a way to increase the material’s tensile properties and decrease the creep relaxation problems that usually plague PTFE products. In addition, the mixing process creates a homogenous material with consistent, superior physical properties that, unlike inexpensive skived PTFE sheet materials, do not fluctuate from one side of the sheet to another.  

Applications:

• Tighter seal
• Improved performance over conventional PTFE
• Reduced product loss and emissions
• Reduced creep relaxation
• Unique manufacturing process minimizes cold flow problems typical of skived and expanded PTFE sheets
• Excellent bolt torque retention
• Chemical resistance - Withstands a wide range of chemicals for extended service life in a wide variety of applications
• Cost savings - Cuts operational costs through reduced:
  • Fluid loss
  • Energy consumption
  • Maintenance costs
  • Inventory costs- Waste. 

Compatible With:

• Moderate concentrations of acids and some caustics
• Hydrocarbons
• Solvents
• Water
• Refrigerants
• Cryogenics, hydrogen peroxide (For oxygen service, specify "Style 3505 for oxygen service.")
