Polyester is a thermoplastic polymer synthesized from polyols and polycarboxylic acids, widely available in both virgin and recycled forms. It is used extensively in textiles, packaging films, beverage containers, and automotive components due to its excellent chemical resistance, ease of processing, and cost-effectiveness. Polyester is favored over alternatives like polycarbonate or nylon when lower cost and good dimensional stability are priorities, though it is often reinforced with glass fiber for structural applications requiring higher stiffness.
