HYTAC® LPX
Thermoset Syntactic Foam
HYTAC® LPX is a new epoxy syntactic plug assist material aimed at providing heavy gauge thermoformers with a proven solution that meets the demands of large plug requirements. HYTAC® LPX is designed for custom-cast requirements where wood cannot provide the required quality and where heated aluminum is too expensive. It 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. LPX is a specialized formulation that enhances friction and reduces the risk of cracking in large geometries. Low thermal conductivity and specific heat Easily machined or formed |
ApplicationsHYTAC-LPX now makes it possible for heavy gauge thermoforming applications to realize the same material distribution/sheet thickness reductions and energy savings as are expected in thin-gauge thermoforming. Resources:
