New Materials and their Properties In the past, with applications requiring the utilization of modified PTFE, certain limitations regarding reverse bending properties had to be accepted. Now ElringKlinger has managed to launch a new product on the market, HS 22121, which combines all the advantages of modified PTFE.
Benefits
- Higher permeation density
- Low cold flow
- Lower porosity
- Smoother surfaces
- Lower Stretch Void Index
- Weldability
- FDA-Approval
In certain aspects, the new material extent even significantly surpasses the excellent reverse bending properties of non-modified standard PTFE types. The combination of these properties was not possible in the past. HS 22121 is equally suitable for use as a diaphragms or bellows. In addition to the high reverse bending resistance, the material’s reduced cold flow improves the retention of the diaphragm and/or bellows in the clamping area; another plus in terms of sealing performance and service life. |
