Plastic is an indispensable part of our current life. It can be understood literally as a material that can be shaped. It is a polymer material. The main component is synthetic polymer compounds, also called synthetic resins. For some properties of the product, some additives will be added to change its properties, so what exactly is plastic and how to distinguish various plastic materials.
Crude oil and natural gas are first extracted, and then sent to refineries, where many substances are extracted, including the main components of plastics, namely ethane from oil, propane from natural gas, ethane and Propane is sent to a cracking plant to be broken down into molecules, ethane is used to make ethylene, and propane is used to make propylene, and then a catalyst is added to combine the molecules to form resinous polymers. Plastics are easily shaped at high temperatures and pressures because of this structure.
Polymerization turns ethylene into polyethylene and propylene into polypropylene. These resins are melted and cooled, and then cut into plastic raw material pellets. The plastic pellets are sent to factories to be heated to make various plastic products.
