Basic knowledge of six common plastics

PE is a polyethylene plastic and has stable chemical properties. It is usually made of food bags and various containers. It is resistant to acids, alkalis, and salts, but it should not be wiped or soaked with strong alkaline detergents.

PP is polypropylene plastic, non-toxic, odorless, can be soaked in boiling water at 100 °C without deformation, no damage, common acid and alkali organic solvents have little effect on it. Used for tableware.

PS is a polystyrene plastic, easy to color, good transparency, used for making lampshades, toothbrush handles, toys, electrical components. It is resistant to acid and alkali corrosion, but it is easily soluble in organic solvents such as chloroform, dichloroethylene, and banana water.

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

ABS is a polymer made of acrylonitrile, butadiene, and styrene. It is eye-catching, heat-resistant, strong, and can be chrome-plated, nickel-plated and other metal films. It can be used to make keys, buttons, knife holders, TV cases, umbrella handles. Wait.

PA is a nylon plastic. Its characteristics are tough, firm, and hard-wearing. It is often used to make combs, toothbrushes, coat hooks, fan bones, mesh bags, and fruit packaging bags. Non-toxic, but not long-term contact with acid and alkali.
