Excellent Material: PVDF
The filament (“yarn”) we spin from the high-tech polymer Polyvinylidene Fluoride (PVDF) is the first guarantee of the high quality of DynaMesh®products: a filament with many positive “natural” properties. The textile structures warp-knitted from this are the second guarantee.
Very high body compatibility
PVDF filaments have excellent biocompatibility and reduce adverse foreign body reactions, such as scar contractions or pain. In addition, they are finer and smoother than conventional filaments. So PVDF is associated with substantially lower granuloma formation (scar tissue) compared with conventional polymers [literature number 2,3,4].
High ageing resistance
It is not just experience that shows that PVDF provides lasting success in many surgical disciplines. A long-term study over seven years has demonstrated that the condition of the PVDF surface remains unchanged. Thread and warp-knitted fabric remain stable and othing becomes brittle [literature number 2].
A long-term trial (7 years):
- PVDF loses only 7.5% tensile strength
- PP loses 46.6% tensile strength
