Product Description

Basic Feature

Material: Premium Modified Expanded PTFE (ePTFE)
Density (at delivery): 0.6 - 0.7 g/cm³
Temperature range: -255ºC - +260ºC
Short-term temperature resistance up to +335ºC
Pressure range: Full vacuum to 320 bar
Chemical resistance: Highly inert to all corrosive media, including strong acids, alkalis, organic solvents and oxidants, pH 0-14

Features

Advanced integral molding and precision calendering process ensures balanced mechanical strength in all directions, greatly reducing the risk of sealing failure.
Effectively resists cold flow, creep and stress relaxation during long-term continuous operation, maintaining consistent sealing performance.
Outstanding flexibility and compressibility, enabling close fit with flange surfaces and enhancing sealing tightness in complex working conditions.

Advantages

Advantage	Description
Excellent Dimensional Stability	No permanent deformation even after long-term compression and repeated rebound, ensuring long-lasting sealing integrity and reducing maintenance frequency.
Easy Machining & On-site Adaptation	Can be quickly cut, punched and customized into various sizes and shapes on site, perfectly matching different flange specifications and installation requirements.
Broad Flange Adaptability	Ideal for enamel, glass-lined, alloy steel and stainless steel flanges, as well as high-precision pressure vessels and reaction equipment.
Effective Flange Surface Compensation	Can well compensate for minor scratches, unevenness and tiny defects on flange faces, avoiding leakage caused by surface irregularities.
Superior Inheritance of PTFE Properties	Retains all the excellent characteristics of pure PTFE, including non-toxicity, non-contamination, high temperature resistance and corrosion resistance, while enhancing overall mechanical strength and sealing reliability.

Reference Applications

Static and dynamic sealing for joints of industrial pipelines, storage tanks, chemical reaction kettles and precision equipment.
Suitable for pressure-sensitive, vibration-sensitive and stress-sensitive connection parts in high-temperature, high-pressure and corrosive environments.
Ideal for sealing in highly corrosive media such as strong acids, strong alkalis, organic solvents, high-purity chemicals and industrial reagents.
Non-toxic, non-polluting and meets the strict hygienic requirements of food, pharmaceutical, medical and beverage industries.
Widely applied in flange connections, pressure vessels, chemical reactors, pumps, valves, compressors and heat exchangers in petroleum, chemical, pharmaceutical, food, electronics and aerospace fields.
