Top-Chem-2000 is a heavy-duty modified PTFE material manufactured with the addition of silicon carbide to improve the mechanical properties of the PTFE base material.

Top-Chem-2003 is a modified PTFE designed for use in low gasket load applications. Glass microspheres aid the compressibility and general mechanical strength without detrimentally affecting the material’s chemical resistance

Top-Chem-2005 is a modified PTFE optimised for use in acidic applications. The addition of glass improves the mechanical properties of PTFE and increases the operational range of PTFE based materials.

Top-Chem-2006 is a modified PTFE optimised for use in alkaline applications. The addition of barium sulphate improves the mechanical properties of PTFE and increases the operational range of PTFE based materials.

Soft-Chem is a pure, expanded PTFE material designed for use in low bolt load applications.
