PTFE Liner
PTFE (polytetrafluoroethylene) is a synthetic fluoropolymer that is used as a liner in catheters due to its unique properties. PTFE has a very low coefficient of friction and is a highly durable material with excellent tensile strength. Catheter liners made of PTFE can withstand the stresses of use in medical devices and resist breaking or tearing.
PTFE is used as a liner in catheters because it provides a smooth, low-friction surface that helps reduce the risk of infection and tissue damage. They are also biocompatible so that most people won’t experience an allergic reaction or any negative response.
