Plastics - Polypropylene And Propylene-copolymers - Determination Of Thermal Oxidative Stability In Air - Oven Method
出版：Nederlands Normalisatie Instituut
专家解读视频
Gives a procedure to determine resistance of moulded test samples of polypropylene and propylene-copolymers to increased ageing by heat in the presence of air by use of a forced draught oven. The procedure attempts to measure the service life of components made from propylene plastics. Stability determined by the procedure is not related directly to material suitability used when different environmental conditions prevail.
