Product Description

Product Description

Basic Feature

Material: Ultra-Durable Modified Expanded PTFE (ePTFE)
Density (at delivery): 0.72 g/cm³
Temperature range: -240ºC - +260ºC
Short-term temperature resistance up to +335ºC
Pressure range: Full vacuum to 290 bar
Chemical resistance: Fully inert to all corrosive media, including strong oxidants, concentrated alkalis and organic solvents, pH 0-14

Features

Advanced precision sintering and composite stretching process ensures balanced mechanical performance in all directions, significantly boosting sealing reliability and service life.
Effectively suppresses cold flow, creep deformation and stress relaxation during long-term continuous operation in extreme industrial environments.

Advantages

Advantage	Details
Superior Compression Stability	Maintains intact dimensions without permanent deformation after long-term compression and repeated rebound, ensuring stable sealing effect and reducing maintenance costs.
Convenient Machining & Fitting	Easy to cut, punch and customize on site, perfectly matching various flange sizes and adapting to complex on-site installation scenarios.
Broad Flange Compatibility	Suitable for enamel, glass-lined, stainless steel and carbon steel flanges, as well as high-precision pressure vessels and chemical reaction kettles.
Reliable Surface Defect Compensation	Effectively offsets minor scratches, unevenness and tiny defects on flange surfaces, avoiding sealing leakage caused by surface imperfections.
Optimized PTFE Performance	Retains all excellent properties of virgin PTFE and further improves compression rebound, wear resistance and overall sealing durability.

Reference Applications

Static sealing for joints of industrial pipelines, storage tanks, chemical reaction equipment and precision mechanical parts.
Suitable for pressure-sensitive, vibration-sensitive and stress-sensitive connecting parts in high-temperature, high-pressure and corrosive working conditions.
Applicable to highly corrosive media such as strong oxidants, concentrated acids, strong alkalis and high-purity organic solvents.
Non-toxic, non-polluting, meeting the strict hygienic standards of food, pharmaceutical, medical and beverage industries.
Widely used in flange connections, pressure vessels, chemical reactors, pumps, valves and compressors in petroleum, chemical, electronic, automotive and marine industries.
