HYTAC® LPXT  

HYTAC® LPXT is a PTFE-impregnated epoxy syntactic plug assist material aimed at providing heavy gauge thermoformers with a robust solution to challenges associated with large, complex part geometries.

HYTAC® LPXT is one of the newest offering in the CMT lineup of syntactic foams engineered for specific plug assist requirements.  LPXT is impregnated with PTFE to provide a smooth, no-stick and mark-off free surface.  It is uniquely formulated to meet the requirements of the custom cast and cure approach used for large, complex part geometries in the heavy gauge thermoforming industry.  A crack-arresting additive ensures product life for cycle after cycle and year after year performance.

HYTAC® LPXT is available as a solid syntactic or as the outer layer of a two-part system consisting of a core of epoxy-coated large, hollow composite spheres and an exterior of high-performance syntactic foam. It has been designed to enhance the cosmetic appearance of parts made from TPO and other capped materials.

Low thermal conductivity and specific heat
The syntactic foam structure of HYTAC® LPXT maintains low thermal conductivity while providing the release characteristics associated with PTFE.

Easily machined or formed
HYTAC® LPXT may be cast to near net shape and/or machined using conventional equipment.

Applications

HYTAC-LPXT now makes it possible for heavy gauge thermoformers to form engineered plastics such as TPO without mark-off or thin spots while improving cosmetic appearance.
