What is EPTFE Gasket Sheet?
EPTFE gasket sheet is produced from 100% multi-directional expanded PTFE without any pigments or adhesives. The flexible EPTFE gasket sheet material adapts well to sealing surfaces, compensates irregularities and seals at very low stress. EPTFE gasket sheet is suitable for use in steel flanges and glass-lined steel flanges, as well as stress sensitive connections.EPTFE gasket sheet is resistant to virtually all chemicals and has excellent creep and cold flow resistance. It is capable of withstanding a wide range of pressure and temperature conditions and is ideal for tight sealing of bolted joints in all process industries including chemical, petrochemical, food, power generation, pulp/paper and general industrial.
Advantanges of EPTFE Gasket Sheet
EPTFE gasket sheet adapts well to sealing surfaces, compensates irregularities and it has superior resistance to creep and cold flow and very high sealability especially at very low stresses. It conforms to FDA requirements.Applications of EPTFE Gasket Sheet
EPTFE gasket sheet material is designed for use in process piping and equipment in chemical, pulp and paper, food and beverage and other general industrial applications where resistance to highly aggressive chemicals is required. EPTFE gasket sheet is suitable for use in steel flanges and flanges with irregular surfaces.Certificate
• EC1935/2004 - suitable for applications with food contact• FDA 21 CFR 177.1550 tested
What is the Difference between PTFE and Expanded PTFE?
PTFE stands for Polytetrafluoroethylene. It is a synthetic fluoropolymer of tetrafluoroethylene. Expanded PTFE is made of 100% pure PTFE which can be used as a sealing agent. It is lightweight but strong. These materials are used for various industrial applications but you should know whether PTFE or ePTFE is better for your application.Why Should You Go for an ePTFE over a PTFE?
Both PTFE and ePTFE have superb industrial applications with excellent features. But the range of application of ePTFE is wider than PTFE. The multi-directional fibrous structure of ePTFE makes it capable of performing at a high surface pressure condition. For maximum safety demands like flange sealing of oxygen-carrying tubes, ePTFE is the appropriate material as it can be highly customized. ePTFE has a better performance rate than PTFE. It has so much demand in the market that it is now manufactured with varying heights, densities, and dimensions.Available size
The width and length can be 1500mm and 1520mm, the thickness of expanded PTFE sheet can be 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 4mm, 5mm, 6mm and 7mm. Other sizes also can be.Shelf Life of EPTFE Gasket Sheet
