PET (POLYETHYLENE TEREPHTHALATE)
PET is a semi-crystalline Polyethylene Terephthalate (PET) polymer that exhibits excellent strength, rigidity, and is easily machined. Additionally, this material offers dimensional stability and wear resistance that meets or exceeds that of polyamide or acetal. Due to it’s superior chemical resistance and food contact approvals, PET sheets and rods are the preferred material for components in food processing applications such as pistons, valves, feed screws, and food product forming and extrusion dies. PET is highly resistant to moisture and chemical resistant to organic material and water. It has a high strength to weight ratio. The low moisture absorption and low rate of thermal expansion makes it ideal for demanding applications that require close tolerance, precisely machined component parts.
