Sunmax 71A2000000 Expanded PTFE Sheet is a high-performance sheet gasket material made of multi-directionally expanded virgin PTFE. It is a soft, form-in-place gasket material that conforms to almost any sealing surface. It is capable of withstanding a wide range of pressure, temperature and chemical environments. Due to its highly fibrillated microstructure, it has excellent creep resistance compared with other PTFE products. It is a food approved product and has excellent resistance to a wide range of chemicals, making it a popular sealing material in the food, drink and pharmaceutical industries.

Excellent mechanical and chemical properties, an immediate, cost effective solution to sealing challenges that demand reliable performance and extended durability.

Application:

Material is used for flange sealing in a wide range of media like oils, petrol water,  acids, etc. at temperature up to 260°C / peak temperature 315°C. It is chemically  inert against the most aggressive acids, except molten alkali metals and  elemental fluorine. Sheets are used for cutting of gaskets and seals for  fragile surfaces as glass, ceramic or glazed flanges. During the bolt tightening process of such flanges it is possible that they are damaged or broken in case the gasket is not soft enough. Therefore, gasket sheets are preferred material for usage when there is risk of breaking the surface of the sealed parts.  Performs as an excellent in the sealing of irregular surfaces, filling even smallest unevenness.
