摘要：This study deals with polypropylene (PP) which was subjected the drop-weight test. PP is a semicrystalline thermoplastic polymer which is commonly used in many indoor applications and also in the automotive industry in the car interiors. The injection moulded PP samples were subjected the penetration test at different fall heights and the results were subsequently evaluated and discussed. It was found out that the fall heights from 100 to 230 J are suitable for PP penetration, but the optimal one is 100 J. Higher heights are not needed because of increasing power consumption of the test device.
