Polytetrafluoroethylene (PTFE)—commonly recognized by the brand name Teflon or celebrated as the "King of Plastics" is a cornerstone material in modern industry. Due to its high chemical resistance, extreme temperature tolerance, low friction coefficient, and [...]

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, [...]

Overview Polytetrafluoroethylene (PTFE) has a distinctive helical molecular conformation. In a PTFE molecule, fluorine atoms form a helical “shell” encapsulating the carbon backbone. This inert perfluorinated helix shields the PTFE main chain from chemical attack. [...]

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 [...]

Expanded PTFE (ePTFE) gaskets—also commonly known as expanded PTFE gasket sheets—are premium sealing materials produced by expanding polytetrafluoroethylene (PTFE). Featuring a robust internal multi-directional fiber structure, ePTFE gaskets significantly surpass traditional gasket materials by offering [...]

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 [...]

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 [...]

Expanded polytetrafluoroethylene (ePTFE) sheets—also known as expanded Teflon sheets—are one of the best sealing solutions, delivering reliability across diverse industrial sectors. Reasoned for their microporous structure, superior chemical resistance, and mechanical resistance, our expanded PTFE [...]

Expanded PTFE (ePTFE) gasket quality directly affects sealing reliability, safety, and service life. Whether you’re doing quick site acceptance or a full laboratory verification for critical service, a good evaluation should cover appearance, dimensional accuracy, [...]

LongSeal Expanded PTFE (ePTFE) gaskets are made from 100% PTFE material that has been expanded into a unique, strong, and porous material. This highly fibrous material retains all the remarkable properties of PTFE itself—such as [...]
