Pet absorption spectrum
Web20. jan 2015 · PET density usually ranges from 1.33 to 1.37 g/cm 3 whereas PVC density ranges in a larger interval 1.10–1.61 g/cm 3 which partially overlaps the PET density range. PVC and PET have been selected among the other plastic polymers because they both have density values larger than 1 g/cm 3 and generally within a small interval.

WebAbsorption Spectra This spectrum is constituted by the frequencies of light transmitted with dark bands when the electrons absorb energy in the ground state to reach higher energy states. This type of spectrum is produced when atoms absorb energy. Let’s know how absorption spectra are formed.
