    en.wikipedia.org/wiki/Anti-scratch_coating

    The anti-corrosion layer protects car metals from environmental harm. Automotive anti-scratch coatings are becoming stronger (from 10 newtons to 15 newtons of protection) to counter scratch resistance lost due to the industry shift from steel to lightweight, but low-scratch resistant plastics and aluminium. Currently, scratch-formation is ...

    en.wikipedia.org/wiki/Polymer_stabilizer

    Aerobic degradation occurs gradually at room temperature, but almost all polymers are at risk of thermal-oxidation when they are processed at high temperatures. The molding or casting of plastics (e.g. injection molding) require them to be above their melting point or glass transition temperature (~200-300 °C). Under these conditions reactions ...

  5. Photo-oxidation of polymers - Wikipedia

    en.wikipedia.org/wiki/Photo-oxidation_of_polymers

    Radicals formed by photolysis may initiate the photo-oxidation in PET. Photo-oxidation of the aromatic terephthalic acid core results in its step-wise oxidation to 2,5-dihydroxyterephthalic acid. The photo-oxidation process at aliphatic sites is similar to that seen for polyolefins, with the formation of hydroperoxide species eventually leading ...
