Comparison of the stress crack resistance of polyethylene grades with the test performance behaviour of packagings for the transport of dangerous goods

  • Technically high-quality hollow articles made of polyethylene have proved many times their value as dangerous goods packagings. Design type tests according to the international regulations for the transport of dangerous goods - drop test, stacking test, hydraulic pressure test and leakproofness test must be performed for every design type and manufacturer. The properties melt flow rate (MFR), relative density (D), low temperature notched Impact strength (N.I.S.) at -30 °C, environmental stress crack resistance (FNCT) and resistance to oxidative degradation Ox by nitric acid (determined by the increase of MFR) have been selected together with the corresponding test methods and tolerances for a comparison of polyethylene grades of one design type in the procedural rule on suitability proof for alternative plastic resins used for dangerous goods packagings and intermediate bulk containers (IBCs) – EN 15507. We wanted to proof the practical relevance of this standard by comparing theTechnically high-quality hollow articles made of polyethylene have proved many times their value as dangerous goods packagings.
