Scope of application
This technical code applies to the heated tool butt welding of panels and to the heated tool butt and sleeve welding of pipes and fittings which are made of PVDF and serve to transport gases, liquids and solids.
Paying attention to the following instructions and on the basis of the practical experience, it may be assumed that melt flow rates MFR1) 230/5 of 1.0 - 25 g/10 min are suitable for densities of 1.70 - 1.80 g/cm³. For this purpose, reference must be made to the data sheets from the suppliers of the semi-finished products - in cases of doubt, Works Certificate 2.1 according to DIN EN 10204.
