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. It is a degradable recycling material.
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. Products made of PET have good transparency, non-toxicity, anti-permeation, light weight, high production efficiency and are therefore widely used.
PET is used in food, medicine, non-toxic and sterile packaging materials. Some high-grade packaging materials are used for textiles, precision instruments, electrical components, decorative products, and color wall stickers. Degradable decorative materials and other environmental protection are good accessories to use in some fields such as audio tapes, video tapes, movie films, computer floppy disks, metal coatings and photosensitive films etc. Electrical insulation materials are used in capacitor films, flexible printed circuit boards, membrane switches, and other electronic and mechanical fields.
PVC material is a kind of plastic decorative material. The full name is polyvinyl chloride material. Its feature is that it takes polyvinyl chloride resin as the main raw material, adding an appropriate amount of anti-aging agent, modifier, etc. then mixing, calendering, vacuum blistering and other processings. Also, PVC material has some special characteristics such as 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.
