PART NUMBER ANALYSIS

To properly select or replace this material

Construction and Documented Properties

SF 5001 is a non-asbestos sheet composed of synthetic fibres and graphite flakes within an NBR nitrile rubber binder. It is not a homogeneous flexible graphite sheet, despite the presence of graphite. At 1.5 mm thickness, the typical density is 1.65 g/cm³, ASTM compressibility is 8.7%, and recovery is 62%. The manufacturer states a maximum temperature of 350°C and a maximum pressure of 100 bar, which cannot be combined simultaneously.

Applications and Service Limits

Manufacturer technical data sheet PDS309 Rev5 lists oils, fuels, steam, water, and dilute acids. It specifically recommends SF 5001 for select concentrated caustic liquors, provided chemical composition and process operating temperatures are verified.

Material Selection and Replacement Analysis

Compared to carbon and aramid fibre-based SF 5000, SF 5001 incorporates graphite flakes within a fibrous NBR sheet. An optional Sark III anti-stick coating is available upon request, but does not imply identical service ratings. The specific media, sheet thickness, flange design, and bolt load must be validated for actual operating conditions.

Comparable grades for technical evaluation: TEADIT NA1100 and Durlon 8900. These do not represent certified direct equivalents.
