Engineering Thermoplastics
PET Glass Filled — Polyethylene Terephthalate, Glass Fiber Reinforced
Glass-filled PET grades exhibit significantly improved mechanical properties, such as higher tensile strength, stiffness, and heat deflection temperature, compared to unfilled PET. This makes them suitable for more demanding engineering applications.
