PART NUMBER ANALYSIS

To properly select or replace this material

The Role of Silicon Carbide

top-chem 2000 utilizes a silicon carbide filler within a modified PTFE matrix. This formulation difference can directly impact load-bearing performance and stress relaxation at elevated temperatures. Key engineering data include pressure/temperature curves, deformation under load, and mechanical test results. The PTFE designation alone does not guarantee that an alternative grade will compress or seal identically.

Comparing Filled PTFE and Expanded PTFE

Garlock GYLON 3500 is silica-filled, whereas other products utilize different filler systems. Expanded PTFEs feature an entirely different structural matrix. An engineered alternative must not only be compatible with the process fluid, concentration, temperature, and flange face condition, but must also achieve proper gasket seating stress using the existing bolting. Relevant certifications and approvals must be verified for the specific grade and thickness supplied.

Required Documentation to Request

For reliable selection, gather the top-chem 2000 technical data sheet, the applicable P/T curve, flange rating, sealing surface finish, operating temperature, and thermal cycling parameters. Then, cross-reference the candidate material's stress relaxation, compressibility, and leakage rate data. Never assume interchangeability based solely on maximum catalog ratings.

Construction and Properties

Silicon carbide (SiC) is the signature filler in KLINGER top-chem 2000. It enhances the PTFE matrix's stability under bolt load and improves creep resistance, particularly as operating temperatures increase.

Applications and Replacement

top-chem 2000 soft provides a higher compressibility profile, whereas grades 2003, 2005, and 2006 incorporate different filler systems. When selecting a replacement, document the process chemicals, concentrations, thermal cycles, and achievable bolt loads on the flange assembly.

To compare material constructions: KLINGER top-chem 2000 soft and KLINGER top-chem 2005. The composition of fillers and reinforcements fundamentally alters gasket performance. Membership in the same PTFE family does not establish functional equivalence.

KEY COMPARISON CRITERIA

Silicon carbide is integral to the technical specification of top-chem 2000. Another material merely designated as PTFE may feature a different filler and mechanical behaviour. Always verify the complete formulation before selecting an alternative.
