Polyether polymer materials, such as polyethylene terephthalate and polyacrylate, are commonly used for spraying white materials in cold storage. Ethylene terephthalate is an amorphous thermoplastic polymer material, which is often used to make bottles, fibers and other products. It has good mechanical properties, chemical stability and heat resistance. PET whitewashed material has good frost resistance and moisture resistance in cold storage, but relatively speaking, its quality and price are slightly higher.
Polyacrylate is a recyclable thermoplastic polymer material, which is widely used in the manufacture of food packaging, household items, medical devices and so on. It has excellent machinability, wear resistance and corrosion resistance. PPA spraying white material shows good waterproof, anti-corrosion and anti-ultraviolet performance in cold storage, and its price is relatively low.
