Product Description

Product Description

Basic Feature

Material: High-Durability Expanded PTFE (ePTFE) with Composite Reinforcement
Density (at delivery): 0.58 - 0.68 g/cm³
Temperature range: -250ºC - +260ºC
Short-term temperature resistance up to +330ºC
Pressure range: Full vacuum to 310 bar
Chemical resistance: Highly inert to all corrosive media, including concentrated acids, strong alkalis, organic solvents and oxidants, pH 0-14 without chemical reaction

Features

Advanced precision stretching and composite molding technology ensures balanced mechanical strength in all directions, effectively avoiding sealing failure caused by uneven performance.
Excellent resistance to cold flow, creep and stress relaxation during long-term continuous operation, maintaining consistent and reliable sealing performance.
Superior flexibility and compressibility, enabling close adhesion to flange surfaces and enhancing sealing tightness in extreme working environments.

Advantages

Stable Compression Performance	Maintains intact shape after long-term compression and repeated rebound, no permanent deformation, ensuring long-term sealing effect and reducing maintenance workload.
Flexible On-site Customization	Easy to cut, punch and adjust into various sizes and shapes on site, perfectly matching different flange specifications and installation needs.
Strong Flange Adaptability	Applicable to enamel, glass-lined, stainless steel and carbon steel flanges, as well as high-precision pressure vessels and reaction equipment.
Effective Surface Defect Compensation	Well compensates for minor scratches, unevenness and small defects on flange surfaces, avoiding sealing leakage caused by surface irregularities.
Superior PTFE Performance Inheritance	Retains all excellent characteristics of pure PTFE, such as non-toxicity, non-contamination, high temperature and corrosion resistance, while improving overall durability and service life.

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 working environments.
Ideal for sealing in highly corrosive media such as concentrated acids, strong alkalis, organic solvents, high-purity chemicals and industrial reagents.
Non-toxic, non-polluting and meets the strict hygiene standards 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, electronic and aerospace industries.
