GRAFILIT SL Gasket Sheet

Product catalog summary
Overview: The document provides technical specifications and guidelines for GRAFILIT® SL, a sealing material composed of expanded natural graphite with a stainless steel foil insert. It is designed for use in demanding industrial applications due to its excellent chemical and thermal resistance.
Material Composition: GRAFILIT® SL consists of over 99% pure expanded natural graphite and a 0.05 mm stainless steel foil insert (AISI 316). The material is black in color and approved by BAM for oxygen applications.
Properties and Performance: The material exhibits superior sealability, thermal resistance, mechanical resistance, and chemical resistance. It is suitable for various industries including chemical, petrochemical, power plants, and more. Typical technical data for a 1.5 mm thickness include a density of 1.3 g/cm³, compressibility of 42%, and recovery of 15%.
Operating Conditions: GRAFILIT® SL can operate at temperatures ranging from -200°C to 700°C, depending on the atmosphere. It can withstand pressures up to 140 bar for liquids and 100 bar for steam and gases.
Chemical Resistance: The document includes a comprehensive chemical resistance chart indicating the material's compatibility with various substances. It is generally recommended for use with many chemicals, though some require technical consultation or are not recommended.
P-T Diagrams: Pressure-Temperature diagrams are provided to guide the maximum permissible combinations of internal pressure and service temperature for the gasket material. Thinner gaskets generally exhibit better P-T properties.
Standard Dimensions: Sheets are available in sizes of 1000 x 1000 mm and 1500 x 1500 mm, with thicknesses ranging from 0.5 mm to 3.0 mm. Custom sizes and thicknesses are available upon request.
Disclaimer: The document notes that the data provided is based on extensive experience but does not support warranty claims. It is subject to change without notice.
