PE is a polyethylene plastic, chemical stability, usually made of food bags and a variety of containers, acid, alkali and salt solution erosion, but not with a strong alkaline detergent wipe or soak. PP is a polypropylene plastic, non-toxic, tasteless, can be soaked in boiling water at 100 ℃ without deformation, no damage, common acid, alkali organic solvents it almost does not work. Used for utensils. PS is a polystyrene plastic, easy to color, good transparency, and more for the production of shade, toothbrush handle, toys, electrical components. It is acid and alkali corrosion, but soluble in chloroform, vinylidene chloride, banana water and other organic solvents. PVC is PVC plastic, bright color, corrosion resistance, durable, due to the increase in the manufacturing process of plasticizers, anti-aging agents and some other toxic auxiliary materials, so its products are generally not stored foods and medicines. ABS is a polymerized plastic made of acrylonitrile, butadiene and styrene. Its color is striking, heat-resistant and sturdy. The outer surface can be chrome-plated, nickel and other metal films. It can be used to make keys, buttons, knife holders, TV housings, Wait. PA is nylon plastic, its characteristics tough, strong, wear-resistant, commonly used in the production of combs, toothbrushes, hooks, fan, net bag rope, fruit bags and so on. Non-toxic, but not long-term and acid-base contact. Five common plastics: polyethylene, polypropylene, polystyrene, PVC, ABS (acrylonitrile - butadiene - styrene copolymer).
