PET is a kind of polymer material, the full name is polyethylene terephthalate, and it is widely used. The bottles of Nongfu Mountain Spring are made of it, which belongs to degradable recycling materials. A

PET mainly includes polyethylene terephthalate (PET) and polybutylene terephthalate (PBT). A

PET molecular structure is highly symmetrical and has a certain degree of crystal orientation, so it has high film-forming and flexibility. PET has good optical properties and weather resistance, and amorphous PET has good optical transparency. In addition, PET has excellent wear resistance and dimensional stability. A

Products made of PET have good transparency, non-toxicity, anti-permeation, light weight, high production efficiency, etc. and are therefore widely used. A

The main uses of PET are: all kinds of food, medicine, non-toxic and sterile packaging materials; high-grade packaging materials for textiles, precision instruments, electrical components; decorative products, color wall stickers, degradable decorative materials and other environmental protection is better Accessories; audio tapes, video tapes, movie films, computer floppy disks, metal coatings and photosensitive films, etc .; electrical insulation materials, capacitor films, flexible printed circuit boards and membrane switches and other electronic and mechanical fields.

PVC material is a kind of plastic decorative material. The full name is polyvinyl chloride material. It takes polyvinyl chloride resin as the main raw material, adding appropriate amount of anti-aging agent, modifier, etc., after mixing, calendering, vacuum blister and other processes Material. A

PVC material has the characteristics of light weight, heat insulation, heat preservation, moisture proof, flame retardant, and easy construction. It is one of the most widely used decorative materials among plastic materials.
