What is the Material: PET-TX is a semi-crystalline material filled with solid lubricant.

Key Material Features: This material is beneficial in applications requiring lower friction, while maintaining properties of other PET materials including toughness, chemical resistance, abrasion resistance, and low moisture absorption.

Other Considerations: This material maintains more strength at higher temperatures than nylon and acetal. In addition, PET lacks center-line porosity, largely found in acetal homopolymer. Also this material is attacked by hot water/steam.
