1. If the slippers are made of plastic, they cannot be changed back. The plastic polymer will decompose under the high-energy rays of the sun and cause damage to the plastic. The main component of plastic is resin. Resin refers to a polymer compound that has not been mixed with various additives. The term resin was originally named after the lipids secreted by animals and plants, such as rosin and shellac.

Resin accounts for about 40% to 100% of the total weight of plastic. The basic properties of plastics are mainly determined by the nature of the resin, but additives also play an important role. Some plastics are basically composed of synthetic resins, with no or few additives, such as plexiglass, polystyrene, etc. Material damage after sun exposure is irreversible.
