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.
Standard flanges (also with larger diameters), apparatus flanges, complex designs
Steel flanges and flanges made of other metal alloys in force main connection
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).
