Product Description

Product Description

Basic Feature

Material: High-Seal Modified Expanded PTFE (ePTFE)
Density (at delivery): 0.73 g/cm³
Temperature range: -249ºC - +260ºC
Short-term temperature resistance up to +336ºC
Pressure range: Full vacuum to 278 bar
Chemical resistance: Inert to all industrial corrosive substances, no chemical reaction or dissolution, fully compatible with pH 0-14 various media

Features

Adopt professional continuous stretching and high-precision sintering technology, ensuring balanced mechanical strength and toughness in all directions, avoiding local performance defects.
Effectively resists cold flow, creep deformation and stress relaxation under long-term continuous high-temperature operation, maintaining stable and reliable sealing performance.
Superior flexibility and proper compression hardness, closely attaching to various flange surfaces without damaging fragile enamel or glass-lined flange materials.

Advantages

Advantage	Detailed Description
Reliable Dimensional Stability	No permanent deformation or shrinkage after long-term compression and repeated assembly-disassembly operations, ensuring consistent sealing effect and prolonging service cycle.
Easy On-site Processing	Can be conveniently cut, punched and shaped on site according to actual flange specifications, suitable for non-standard sizes and emergency installation needs.
Versatile Flange Adaptability	Compatible with enamel flanges, glass-lined flanges, stainless steel flanges and carbon steel alloy flanges, as well as high-precision pressure vessels and chemical reaction equipment.
Effective Flange Defect Compensation	Effectively offsets slight scratches, surface unevenness and minor wear on flange sealing surfaces, avoiding medium leakage caused by surface imperfections.
Upgraded Virgin PTFE Properties	Retains all core advantages of virgin PTFE including non-toxicity, non-contamination and corrosion resistance, while enhancing sealing stability and wear resistance in harsh industrial conditions.

Reference Applications

Static sealing for connecting joints of industrial pipelines, storage tanks, reaction kettles and purification equipment.
Ideal sealing choice for pressure-sensitive, vibration-sensitive and stress-sensitive connecting parts in severe industrial environments.
Suitable for sealing various corrosive media including concentrated inorganic acids, strong organic alkalis, industrial solvents and high-purity chemical agents.
Non-polluting and hygienic, complying with the sealing standards of food processing, pharmaceutical production and fine chemical fields.
Widely applied in flange connections, pressure vessels, chemical reactors, centrifugal pumps, valves, compressors and heat exchangers in petrochemical, pharmaceutical, food and environmental protection industries
