multiFlon® PRO and GMP

multidirectionally expanded PTFE gasket sheets

multidirectional ePTFE sheets for highest demands on purity and conformity, FDA, EG1935 and GMP compliant

multiFlon® PRO – gasket sheets are made of 100% pure, multidirectionally expanded PTFE, with virtually unlimited chemical resistance.

When installed, gaskets made of multiFlon® PRO gasket sheets have exceptionally good adaptability to flange roughness and unevenness.

During operation, a high surface pressure is maintained even under high pressure and temperature loads. As a result, multiFlon® PRO achieves very good stability and tightness, especially in demanding steel flange applications, with high blow-out safety.
The good recovery behaviour of the material leads to increased operational safety even under changing operating conditions.

For demanding applications with high purity requirements, multiFlon® PRO-GMP gasket sheets are available in the embossed version.

Typical applications
  • Components
    Standard flanges (also with larger diameters), apparatus flanges, complex designs
  • Flanges
    Steel flanges and flanges made of other metal alloys in force main connection
  • Media
    Sealing of pipelines and apparatus with highly aggressive media, applications in the food industry, use in pharmaceutical applications (multiFlon® PRO gasket sheets are also available neutral/unprinted or embossed).
