Scope of application
This technical code applies to welding by bending using a heated tool for panels made of polypropylene1) (PP-H, PP-B and PP-R) according to DIN EN ISO 15013 and for panels made of PE1) according to DIN EN ISO 14632.
Paying attention to the instructions in this technical code, weldability may be assumed within the melt flow rates MFR2) 190/5 named below:
1 0.4 - 1.0 g/10 min (PP) - approximately corresponds to the melt flow rate MFR2) 230/2.16 of 0.2 - 0.6 g/10 min
2 0.3 - 1.7 g/10 min or 0.2 - 0.7 g/10 min (PE)
The main areas of application for welding by bending using a heated tool are in tank and apparatus construction as well as in ventilation and air conditioning technology. DVS 2207-1 and DVS 2207-11 are technical codes which are also applicable.
1) The material designation should be understood as a generic term for the group of thermoplastics and includes the PE 63, PE 80 and PE 100 types. The information corresponds to the current status of the standardisation.
2) MFR = melt flow rate (old designation: MFI = melt flow index)
