Custom Size Eptfe Gasket Chemical Resistant Sealing Washer

Product Description

Product Description

Basic Feature

Material: High-Toughness Modified Expanded PTFE (ePTFE)
Density (at delivery): 0.71 g/cm³
Temperature range: -248ºC - +260ºC
Short-term temperature resistance up to +332ºC
Pressure range: Full vacuum to 275 bar
Chemical resistance: Highly inert to all industrial corrosive substances, no chemical reaction or dissolution, pH 0-14

Features

Adopt advanced integral stretching and precision sintering technology, ensuring balanced mechanical strength and ductility in all directions, eliminating local performance deficiencies.
Effectively resists cold flow, creep deformation and stress relaxation under long-term high-temperature and high-pressure operation, maintaining reliable sealing performance without failure.
Excellent flexibility and moderate compression hardness, closely fitting various flange surfaces without causing damage to fragile flange materials.

Advantages

Advantage	Detailed Description
Superior Dimensional Retention	No permanent deformation or shrinkage after long-term compression and repeated assembly-disassembly, maintaining consistent sealing effect and extending service life.
Easy On-site Customization	Can be conveniently cut, punched and trimmed on site according to actual installation needs, suitable for non-standard flange sizes and urgent installation scenarios.
Strong Flange Compatibility	Applicable to enamel flanges, glass-lined flanges, carbon steel flanges and alloy flanges, as well as high-precision pressure vessels and reaction tanks.
Effective Flange Surface Compensation	Effectively compensates for slight scratches, surface irregularities and minor wear on flange sealing faces, preventing medium leakage caused by surface defects.
Upgraded Virgin PTFE Performance	Retains all core advantages of virgin PTFE such as non-toxicity, non-pollution and corrosion resistance, and enhances sealing stability and wear resistance for harsh working environments.

Reference Applications

Static sealing for connecting joints of industrial pipelines, storage tanks, reaction kettles and purification equipment.
Perfect sealing solution for pressure-sensitive, vibration-sensitive and stress-sensitive connecting parts in harsh industrial environments.
Suitable for sealing various corrosive media including strong inorganic acids, organic alkalis, industrial solvents and high-purity liquid media.
Non-contaminating and hygienic, meeting the sealing standards of food processing, pharmaceutical manufacturing and fine chemical industries.
Widely used in flange connections, pressure vessels, chemical reactors, centrifugal pumps, valves, compressors and heat exchangers in petrochemical, pharmaceutical, food and environmental engineering industries.
