Polymers, which are long chains of repeating molecular units, can be naturally occurring or synthetic. The latter, including plastics like polyethylene, polypropylene, and polystyrene, dominate the market due to their adaptability and cost-effectiveness. The versatility of these materials allows them to be molded into almost any shape, making them ideal for countless applications. As a result, polymer material factories are at the forefront of innovation, contributing to advancements in material science and engineering.
