Similarly, in PE and PP the presence of chromophores in PVC due to impurities can absorb UV radiation and generate free radicals. The free radicals form hydroperoxides that can break the double bonds of the backbone chain and generate smaller degradation products (Law 2016; Yang et al., 2018).

These materials absorb light in the ultraviolet region below 380 nm and emit at longer wavelengths in the blue part of the spectrum. This gives the appearance of extra whiteness, as in some cases blue light reflected from the sample is more than the blue light incident on it, due to the conversion of UV radiation into blue light emission.
White surfaces can reflect a considerable amount of light, but without the mobile electrons to oppose the electric field of light, white surfaces allow light to penetrate up to several wavelengths. This allows them to experience multiple reflections from crystal grains and other irregularities within the structure of the surface.
