Quantity
Gylon 3500 Flange Gaskets are high-performance non-metallic insulating gaskets that comply with the ASME B16.5 standard. Manufactured from modified PTFE material, they combine exceptional temperature resistance (-268°C to 260°C) with pressure-bearing capability (150LB). Designed specifically for 12-inch piping systems and used in conjunction with G10 sleeves, washers, and ZPS components, they provide a comprehensive sealing and insulation solution, suitable for corrosion prevention and electrical isolation requirements in demanding service conditions.
How is the creep resistance and stress relaxation resistance of Gylon 3500? Can it maintain sealing under long-term high temperatures?
Gylon 3500 Flange Gaskets demonstrate outstanding performance in creep resistance and stress relaxation resistance, providing reliable and long-lasting sealing even under long-term high-temperature conditions. This is primarily attributed to the unique material formulation and manufacturing process of these high-performance Gylon 3500 Flange Gaskets.

Interpretation of Creep and Stress Relaxation Resistance
The excellent creep and stress relaxation resistance of Gylon 3500 Flange Gaskets is mainly due to the following characteristics:
Silica-Filled Modified PTFE: Gylon 3500 Flange Gaskets utilize a high-performance modified Polytetrafluoroethylene (PTFE) material, with silica added as a filler. This filling modification effectively inhibits the slippage of PTFE molecular chains under the influence of stress and temperature, thereby significantly enhancing the material's ability to resist slow shape change under long-term static load (i.e., creep resistance).

Unique Manufacturing Process: Through a unique manufacturing process, Gylon 3500 Flange Gaskets minimize the inherent"cold flow"issue associated with the cutting and expansion of PTFE sheets. Cold flow is the tendency of PTFE material to undergo plastic deformation over time under pressure and is one of the primary causes of sealing failure. This process directly enhances the gasket's creep resistance.
Excellent Bolt Torque Retention: This indicates that Gylon 3500 Flange Gaskets can effectively maintain the sealing compression stress generated by the initial bolt tightening, resisting the decay of this stress during temperature and pressure cycles (i.e., stress relaxation resistance). Consequently, the flange connection remains tight over long-term operation.
Analysis of Long-Term High-Temperature Sealing Performance
Regarding sealing durability under long-term high temperatures, Gylon 3500 Flange Gaskets also demonstrate reliable performance:
Broad Operating Temperature Range: The applicable temperature range for Gylon 3500 Flange Gaskets is -268°C to 260°C. This means that even at a high temperature of 260°C, it can maintain the stability of its material structure and properties.

Stable Performance under High Temperature and Pressure: According to product specifications, the maximum PxT value (Pressure x Temperature product) for 1/16-inch thick Gylon 3500 Flange Gaskets can reach 350,000 °F x PSIG. This parameter comprehensively reflects the material's load-bearing and sealing capacity under the combined action of high temperature and pressure; a higher value generally indicates greater reliability of its long-term high-temperature sealing performance.
Practical Application Evidence: Gylon 3500 Flange Gaskets are recommended for use in various industries such as chemical, pharmaceutical, and food processing, capable of handling aggressive media including strong acids (except hydrofluoric acid), solvents, hydrocarbons, and steam. For instance, their long-term sealing stability has been verified in piping systems potentially involving high-temperature steam.
Summary
In conclusion, leveraging the material properties of silica-filled PTFE and its unique manufacturing process, Gylon 3500 Flange Gaskets provide exceptional creep resistance and stress relaxation resistance. This enables Gylon 3500 Flange Gaskets to persistently maintain the sealing integrity of flange connections across a broad temperature range from -268°C to 260°C, even under long-term exposure to high temperatures and pressure cycling conditions, making them a reliable choice for many demanding applications.
