Performance and use of common plastics

PE is polyethylene plastic, its chemical properties are stable. It usually produces food bags and various containers, and is resistant to acid, alkali and salt solution. But it is not suitable to wipe or soak with strong alkaline detergent.

PP is a polypropylene plastic, non-toxic, tasteless, can be 100 degrees in the boiling water soak deformation, no damage, common acid, alkali and organic solvent on it is almost no effect. For more food.

PS is polystyrene plastic. It is easy to stain and has good transparency. It is used for making lampshade, toothbrush handle, toys and electrical components. It is resistant to acid and alkali corrosion, but it is easily dissolved in chloroform, two vinyl chloride, banana water and other organic solvents.

PVC is polyvinyl chloride plastic, bright color, corrosion-resistant and durable. Due to the addition of some plasticizers, anti-aging agents and other toxic auxiliary materials in the manufacturing process, its products generally do not store food and drugs.

ABS is made from acrylonitrile, butadiene and styrene. Its color is striking, heat-resistant and strong. The outer surface can be plated with chromium, nickel and other metal thin films. It can make keyboard, button, knife rack, TV case, umbrella handle and so on.

PA nylon plastics, its characteristic tenacity, strong wear resistance, commonly used in the production of comb, toothbrush, rope bag, hook, a fan, fruit bags. No toxicity, but not long-term contact with acid and alkali.
