Product Description

Product Description

Basic Feature

Material: Wear-Resistant Modified Expanded PTFE (ePTFE)
Density (at delivery): 0.66 g/cm³
Temperature range: -247ºC - +260ºC
Short-term temperature resistance up to +334ºC
Pressure range: Full vacuum to 290 bar
Chemical resistance: Highly inert to all corrosive industrial media, no reaction or dissolution occurs, fully compatible with pH 0-14 media

Features

Adopt advanced multi-station stretching and precision sintering technology, ensuring uniform mechanical strength and ductility in all directions, eliminating local performance weaknesses.
Effectively inhibits cold flow, creep deformation and stress relaxation under long-term continuous high-pressure operation, maintaining consistent and stable sealing performance.
Exceptional flexibility and optimal compression hardness, closely fitting various flange surfaces without causing damage to fragile glass-lined or enamel flange materials.

Advantages

Advantage	Detailed Description
Stable Dimensional Performance	No permanent deformation or shrinkage after long-term compression and repeated assembly-disassembly processes, ensuring consistent sealing effect and extending service life.
Hassle-free On-site Customization	Can be easily cut, punched and tailored on site according to actual flange sizes, suitable for non-standard specifications and urgent installation scenarios.
Broad Flange Compatibility	Compatible with enamel flanges, glass-lined flanges, stainless steel flanges and alloy steel flanges, as well as high-precision pressure vessels and chemical reaction kettles.
Efficient Flange Defect Offset	Effectively compensates for slight scratches, surface unevenness and minor wear on flange sealing faces, preventing medium leakage caused by surface defects.
Enhanced Virgin PTFE Performance	Retains all core advantages of virgin PTFE such as non-toxicity, non-pollution and corrosion resistance, while upgrading sealing reliability and wear resistance in harsh industrial environments.

Reference Applications

Static sealing for connecting joints of industrial pipelines, storage tanks, reaction kettles and separation equipment.
Perfect sealing solution for pressure-sensitive, vibration-sensitive and stress-sensitive connecting parts in harsh industrial environments.
Suitable for sealing various corrosive media including concentrated organic acids, strong alkalis, industrial solvents and high-purity chemical reagents.
Non-contaminating and hygienic, meeting the sealing standards of food processing, pharmaceutical manufacturing and fine chemical industries.
Widely applied in flange connections, pressure vessels, chemical reactors, gear pumps, valves, compressors and heat exchangers in petrochemical, pharmaceutical, food and environmental engineering fields.
