Have you looked carefully at the back or bottom of a plastic product? If you look closely, you can find words such as PP, PS, LDPE, and HDPE.
They refer to plastic materials. While they may look like same plastic, they are actually made of different materials.
The raw materials that are used to make plastics are called synthetic resins, which are petrochemical products made from petroleum.
When crude oil is refined at its boiling point, it results in various types of oils. Of these, naphtha is the raw material used to make petrochemical products.
When naphtha undergoes pyrolysis at a decomposition facility, it creates basic ingredients for petrochemical products, including ethylene, propylene, and butadiene.
This facility is called the "naphtha cracking center (NCC)," which is the starting point for making petrochemical products.
The basic raw materials created at the NCC go through several processes to be produced as the final product that we use.
Plastic products are widely used in our daily life in various shapes and applications, such as tires, clothing, paint, and adhesives.
