COLOUR: White SERVICE: Sigma 600 is specifically designed for use in flanges where only low bolt loading is available. Such flanges can be glass lined, ceramic, plastic or be so distorted that they include areas of low gasket stress. Suitable for sealing all chemicals across the whole pH range (0-14) with the exception of molten alkali metals and fluorine gas. Consisting entirely of pure PTFE, this material is suitable for use with hydrogen fluoride. Maximum recommended temperature: 260OC (500OF) Maximum recommended pressure: 8.5 MPa (85 bar; 1235 psi) These temperature and pressure guides cannot necessarily be used simultaneously and may not apply at all thicknesses. Complies with the requirements of FDA regulations. Do NOT use gasket pastes.

HEALTH AND SAFETY Because of the processes which take place during manufacture, the product is believed to present no health and safety hazard and, under normal handling and use it is unlikely that the product will give rise to significant levels of exposure to constituent materials. SIGMA 600 contains PTFE. Under harsh mechanical treatment (e.g. high speed stamping operations or abrasion) the constituents may give rise to irritant dusts which, in extreme cases of exposure, could lead to more serious respiratory problems. Occupational exposure to such dusts should therefore be minimised and...
