PTFE Materials
Description
Jinyou ePTFE sheet offers a wide service range across applications in various process industries. The patented UFG multilayer manufacturing method provides reliable sealability, thanks to the material’s low stress and exceptional dimensional stability. This gasket material is produced by expanding 100% pure polytetrafluoroethylene (PTFE) into a highly fibrillated, bi-directional, soft, and compressible sheet, ensuring longer service life and trouble-free sealing. Its form-in-place versatility makes it ideal for flange surfaces that are worn, warped, or scored. The distinct compressibility of the UFG sheet allows it to effectively fill flange imperfections, creating a tight, leak-free seal. Unlike conventional PTFE materials prone to cold flow, Jinyou ePTFE sheet demonstrates excellent creep resistance and bolt torque retention.
The material exhibits outstanding chemical resistance across a pH range of 0–14, making it suitable for most media. Temperature service limits range from -268 °C (-450 °F) to 260 °C maximum, with spikes up to 315 °C (600 °F), and pressure ranges from full vacuum to 206 bar (3,000 psi). These exceptional properties are achieved without the need for fillers such as silica, barium sulfate, or hollow glass spheres. The UFG gasket material is suitable for both high-load metal-flanged applications and low-load applications such as glass-lined steel, glass, and FRP (fiberglass reinforced plastic) piping and vessels. It does not support bacterial growth or cause product contamination and is compliant with FDA 21 CFR 177.1550.
Jinyou ePTFE sheet has an unlimited shelf life and is unaffected by normal environmental conditions.
Beyond its standalone capabilities as a reliable seal in highly corrosive environments, it is also widely used as the primary sealing element in semi-metallic gaskets such as spiral-wound and corrugated types.
By using Jinyou ePTFE sheet, concerns related to process safety and production downtime caused by incorrect gasket materials are greatly reduced.
