What is the Material: This is a food grade acetal homopolymer filled with PTFE (Teflon). This material is known by the tradename TECAFORM HPV 13. It is a semi-crystalline material.

Key Material Features: This material is beneficial in applications requiring low friction, toughness, low moisture absorption, and wear resistance.

Other Considerations: This material has chemical resistance very similar to unfilled acetal homopolymer.
