Polytetrafluoroethylene (PTFE) is a high-polymer compound with fluorine atoms in the main chain of its molecule. Due to the high dissociation energy of the C-F bond in the molecule, as well as the high electronegativity [...]
1 — Introduction: A New Way to Look at Sealing Economics In the complex ecosystem of modern heavy industry and precision manufacturing, fluid sealing technology is often physically small but disproportionately critical to operational safety, [...]
Expanded PTFE (ePTFE) has revolutionized the sealing industry. By modifying traditional Polytetrafluoroethylene (PTFE) through a biaxial stretching and lamination process, ePTFE retains PTFE's legendary chemical resistance while addressing its two biggest weaknesses: high creep (cold [...]
Polytetrafluoroethylene (PTFE) is a fluoropolymer renowned for its exceptional chemical resistance and ultra-high purity. PTFE sheet and rod exhibit self-lubricating behavior and a very low coefficient of friction, making them ideal for high-temperature seals, insulators, [...]
Gland Packing (also called sealing packing or braided packing) is usually braided from relatively soft, flexible yarns and is installed in the stuffing box as a strip-shaped sealing element to prevent media leakage. In early [...]
Expanded PTFE gasket tape is a sealing material offered as continuous, white, 100% ePTFE tape. It is known for its excellent flexibility, compression resilience, and ease of installation, making it a popular choice in various [...]
Reliable gland packing (compression packing) is one of the most cost-effective ways to control leakage, improve uptime, and meet environmental requirements in industrial fluid systems. Whether you’re sealing a pump shaft, agitator, or valve stem, the packing material you choose [...]
From PTFE Chemistry to ePTFE Performance Polytetrafluoroethylene (PTFE) is renowned for its excellent chemical stability, wide service temperature range, electrical insulation properties, low friction, and anti-stick characteristics. It has one of the lowest coefficients of [...]
In petrochemical, metallurgy, and nuclear plants, bolted flange connections rely on gaskets to prevent leaks in pressure vessels and piping. Under high-temperature and high-pressure conditions, the sealing performance and reliability must be exceptional. Any leakage [...]
In the production processes of the petroleum, chemical, and pharmaceutical industries, equipment such as pipelines, valves, and pressure vessels is interconnected through passages. To prevent leakage at every flange joint, a sealing gasket is typically [...]
