Polyester moisture-resistant rods, also known as Polyethylene terephthalate rods, are used in fibers for clothing, containers for liquids and foods, thermoforming for manufacturing, and in combination with glass fiber for engineering resins. These rods are stable, produce little friction, and resist acidic solutions. With low moisture absorption, they are used in mechanical and electrical applications. They are commonly used for manufacturing precision mechanical parts that must sustain high loads and withstand persistent wear. They are also suitable for parts used in food processing equipment.
