Product Description

Product Description

Basic Feature

Material: Reinforced Expanded PTFE (ePTFE)
Density (at delivery): 0.68 g/cm³
Temperature range: -245ºC - +260ºC
Short-term temperature resistance up to +325ºC
Pressure range: Full vacuum to 270 bar
Chemical resistance: Inert to all common corrosive media, including strong acids, alkalis and organic solvents, pH 0-14

Features

Advanced composite stretching and sintering process ensures consistent mechanical performance in all directions, improving sealing stability and service life.
Effectively prevents cold flow, creep deformation and stress relaxation under long-term high-temperature and high-pressure working conditions.

Advantages

Advantage	Details
Stable Compression Rebound	Maintains stable dimensions without permanent deformation after repeated compression and rebound, ensuring long-term sealing integrity.
Easy Machining & Installation	Convenient to cut, punch and process on site, adaptable to various flange sizes and installation scenarios.
Wide Flange Compatibility	Perfectly suitable for enamel, glass-lined, stainless steel flanges and high-precision pressure vessels.
Flange Surface Compensation	Effectively compensates for minor scratches, unevenness and tiny damages on flange faces, avoiding sealing leakage.
Superior PTFE Performance	Inherits all excellent properties of virgin PTFE and enhances sealing reliability and wear resistance.

Reference Applications

Static sealing for pipelines, storage tanks, reaction kettles and other industrial equipment joints.
Suitable for pressure-sensitive, vibration-sensitive and stress-sensitive connecting parts in harsh environments.
Applicable to highly corrosive media such as strong acids, alkalis, organic solvents and high-purity chemicals.
Non-toxic, non-polluting, meeting the hygienic requirements of food, pharmaceutical and medical industries.
Widely used in flange connections, pressure vessels, chemical reactors, pumps, valves and compressors in petroleum, chemical and electronic industries.
