DONIFLON 2020 Gasket Sheet-1

Qdonit* DONIFLON® 2020 is structurally enhanced PTFE gasket sheet filled with silica. It has outstanding chemical resistance to various media, same as DONIFLON® 900E; especially recommended for inorganic acids in all concentrations, except hydrofluoric acid. This material has enhanced creep performance compared to plain PTFE material. It is recommended for pharmaceutical and food industries as well as LNG & cryogenic applications. GENERAL PURPOSE POTABLE WATER SUPPLY STEAM SUPPLY GAS SUPPLY CHEMICAL INDUSTRY PETROCHEMICAL INDUSTRY PROPERTIES SEALABILITY CHEMICAL PERFORMANCE RESISTANCE ■ General suitability - Under common installation practices and chemical compatibility. Conditional suitability - Appropriate measures ensure maximum performance for joint design and gasket installation. Technical consultation is recommended. Limited suitability - Technical consultation is mandatory. P-T diagram indicates the maximum permissible combination of internal pressure and service temperature which can be simultaneously applied for a given gasket's 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.
