PBT Lubricated

PBT Lubricated


What is the Material: PBT Lubricated is a semi-crystalline material filled with a proprietary lubricant and PTFE (Teflon).

Key Material Features: This material is beneficial in applications requiring a lower coefficient of friction and higher wear resistance, while maintaining properties of other PBT materials including including impact resistance, chemicals resistance, and low moisture absorption.

Other Considerations: It has diverse resistance to many common cleaning chemicals. This material has higher impact resistance than PET.
