Fig. 5From: Quantifying the fragmentation of polypropylene upon exposure to accelerated weatheringA-D SEM images of PP with stabilizer and E-H without stabilizer. A&E Virgin particles, reference material, B&F smoothed particles after 200 h, C&G particle fragments after 800 h and D&H particle surfaces after 2000 h. Smaller particles in the nanometer-range are visible on the surfacesBack to article page
