Constantly bend a point, the molecular chain at this point keeps moving, part of the work you do on the material is converted into the kinetic energy of the molecule, and part of it is converted into the heat generated by the friction of the chain.
When the heat accumulates to a certain level, coupled with the poor thermal conductivity and heat resistance of the polymer, the temperature will rise, and the polymer segment at that position will be oxidized and decomposed, and you can Smells of burning.
