DetailsReplaces Ultimaker2 teflon part but this part can print at 255C continuous for years. Never replace your teflon part again. This is made of PTFE but it's a high temperature teflon. First there was regular PTFE (both Ultimaker and 3dsolex). Then there was "TFT" (3dsolex and soon after Ultimaker). Now there is "TFN".
