TenCate Polyfelt - Model F - Filter Fabrics
TenCate Polyfelt F filter fabrics are geocomposites, consisting of two layers of mechanically bonded continuous-filament nonwoven made from 100% UV-stabilised polypropylene. One filament layer is designed as a filter, the other as a protection layer preventing mechanical damage to the filter. The optimised opening size and number of constrictions ensure excellent long-term filter performance.
The Benefits of TenCate Polyfelt F at a Glance:
- Optimum number of constrictions for excellent filter performance: adequate soil retention capability, minimum danger of internal clogging, and an opening size suitable for almost all types of soil
- High water permeability
- High filter stability: Due to the non-woven structure, the hydraulic and mechanical properties do not change significantly under mechanical stress, unlike wovens
- Two layers fulfilling two completely different requirements: high filter performance, and high mechanical resistance
- The continuous filaments of F have an indefinite anchor length, so that they cannot be dissolved from the fiber structure under cyclic mechanical stresses such as wave actions.
