The plastics industry is considered one of the most important industries in the modern era, as it is used in a wide range of applications in daily and industrial life. Many economic sectors depend on plastics and their technologies in production and manufacturing processes. It is important to understand the impact that the plastics industry has on the environment and the challenges it faces, in addition to studying innovations and developments in this field to improve its sustainability.
History of the plastic industry:
The history of the plastics industry dates back to the nineteenth century, when the processes of developing plastic materials and discovering polymers began. In 1907, the first synthetic plastic was invented by German scientist Leo Henzel. This new invention was used in a variety of industries, leading to increased interest and development over the following years. Thanks to modern technical developments and innovations, the plastics industry has played an important role in many industrial and life sectors.
Types of plastic and their uses
Types of plastic vary according to their uses in industry, as they are used in the manufacture of household appliances, containers, covers, pipes, electrical wires and cables, and other uses. The properties of each type depend on its chemical composition, density, strength, hardness and elasticity. Common plastics include: polyethylene, polypropylene, polyvinyl chloride, polystyrene, polycarbonate, polyethylene terephthalate, polyurethane and others.
Polyethylene
Polyethylene is considered one of the most widely used types of plastic in the world, as it is characterized by its strength, rigidity, flexibility, and light weight. Polyethylene is used to make plastic bags, bottles, pipes, and electrical insulation applications. Polyethylene is divided into two main types: high-density and low-density, with each type characterized by its own characteristics and uses.
