HYTAC® WFT improves on the strength and clarity of the popular HYTAC® WF through the incorporation of PTFE into the formulation. The result is a 425°F (218°C) high temperature syntactic plug material for use where excessive buildup of residue from the sheet is a problem. HYTAC® WFT may be easily polished for use where a smooth surface is critical to part quality.
