PBT Ultra Detectable


What is the Material: PBT Ultra Detectable is a semi-crystalline material filled with a multi detectable filler.

Key Material Features: This material is beneficial in applications requiring increased food safety, while providing many benefits of other PBT materials including impact resistance, chemicals resistance, wear resistance, low coefficient of friction, and low moisture absorption.

Other Considerations: The filler makes the material detectable using x-ray imaging, metal detection, and by optical scanners. This material has higher impact resistance than PET.
