Soft Flexible Eptfe Gasket Anti-Creep Expanded PTFE Sealing Gasket

Product Description

Product Description

Basic Feature

Material: Enhanced Expanded PTFE (ePTFE)
Density (at delivery): 0.65 - 0.75 g/cm³
Temperature range: -260ºC - +260ºC
Short-term temperature resistance up to +330ºC
Pressure range: Full vacuum to 300 bar
Chemical resistance: Completely inert to most chemicals, acids, alkalis and organic solvents, pH 0-14

Features

Advanced composite molding technology ensures consistent tensile strength and elongation in all directions, improving overall sealing stability.
Effectively prevents cold flow, creep and stress relaxation even under long-term high-temperature and high-pressure working conditions.
Excellent compression rebound performance, maintaining reliable sealing effect after multiple disassembly and assembly.

Advantages

Advantage	Description
Stable Dimensional Performance	No permanent deformation after compression and rebound, ensuring long-term sealing integrity.
Easy Machining & Installation	Can be easily cut, punched and trimmed on site, adapting to various flange sizes and installation scenarios.
Wide Flange Adaptability	Perfect for enamel, glass-lined, carbon steel and stainless steel flanges, as well as precision pressure vessels.
Flange Surface Compensation	Effectively compensates for minor scratches, unevenness and tiny damages on flange faces, improving sealing tightness.
Superior PTFE Inheritance	Retains all inherent advantages of pure PTFE (non-toxic, non-contaminating, corrosion-resistant) while enhancing wear resistance and sealing reliability.

Reference Applications

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