Technical data sheet - GRAFILIT® SP-Pure GRAFILIT® SP-Pure GRAFILIT® SP-Pure is a gasket material made of high-quality expanded graphite mechanically bonded to tanged stainless steel foil. Its properties profile matches the production applications for foodstuff and consumables, where integrity and hygiene are the top priorities. With its excellent chemical resistance and operating temperature ranging from -200 to +550°C, this food-grade gasket material can be used extensively in a variety of food and beverage processing equipment. The material is taint- and taste-free and withstands harsh conditions during equipment operation as well as cleaning and sterilization.

Technical data sheet - GRAFILIT® SP-Pure EN 1514-1, Type IBC, PN 40, DIN 28091-2 / 3.8, 1.5 mm P-T diagrams indicate the maximum permissible combination of internal pressure and service temperature which can be simultaneously applied to a given gaskets thickness, size and tightness class. Given the wide variety of gasket applications and service conditions, these values should only be regarded as a guidance for the proper gasket assembly. In general, thinner gaskets exhibit better P-T properties. Aggressive gasses ■ General suitability - Under common installation practices and chemical compatibility...
