Rulon J


What is the Material: Rulon J is a semi-crystalline material. It is a modified PTFE (Teflon) filled with a proprietary polymer additive.

Key Material Features: This material is beneficial in applications requiring low friction, wear resistance, and self-lubricating properties.

Other Considerations: It is ideally suited in applications where slip-stick of start/stop applications must be eliminated. It does not perform well in tight tolerance applications.
