Compressed Fibre

Product catalog summary

Product Overview:
The document provides detailed specifications and applications for various compressed fiber and graphite sheet materials, including SF1630, SF2401, SF2420, SF3300, SF3500, SF5000, AF2100, Flexicarb ST, and Flexicarb SR. These materials are used in sealing applications across different industries.

Specifications:
- Sheet Sizes: Available in 60” x 60” and 60” x 120”, with other sizes on request.
- Thicknesses: Range from 1/64” to 1/8”, with custom thicknesses available.
- Density: Varies by product, e.g., SF1630 has a density of 112 lb/ft³ (1.8 g/cc).
- Compressibility and Recovery: ASTM F36 standards are used to measure these properties, with compressibility ranging from 7.5% to 18% and recovery from 52% to 68%.

Service & Application:
- SF1630 is ideal for hydrotesting and low-temperature, non-critical applications, suitable for sealing water and mild chemicals.
- SF2401, SF2420, and SF3300 are suitable for sealing steam, water, gases, oils, and mild solvents.
- SF3500 and SF5000 offer increased strength and are ideal for use in pumps and sealing caustic liquors.

Performance Parameters:
- Maximum Temperature: Ranges from 356°F (180°C) to 887°F (475°C) depending on the material.
- Maximum Pressure: Ranges from 1015 psi (70 bar) to 3000 psi (207 bar).
- pH Range: Typically from 3 to 14, depending on the material.

Chemical Resistance:
The document includes a comprehensive chemical resistance chart indicating the suitability of each material for various chemicals. For example, SF2401 is suitable for acetic acid, acetone, and air, but not for aqua-regia or bromine.

Gasket Constants:
- ASME m and Y values are provided for each material, indicating their mechanical properties under stress.

Additional Notes:
- The document emphasizes that the data provided is for guidance only and does not constitute a warranty of suitability for specific applications.
- Antistick coating is standard on compressed fiber sheets, and materials are recommended for class 150 and 300# flanges.
