EconCore Honeycomb ThermHex are hexagonal honecomb cores from a range of thermoplastic polymers. These include for example PP, PE, PET, PLA, PVC, ABS, PC, PPS, PEI, and many others.

During a first production step the polymer resin is extruded into a film, vacuumformed and folded to a honeycomb core. In a second step in the production line skins are laminated onto the core. Thermoplastic skins of the previously mentioned thermoplastic polymers can be added, but also glass fiber filled, CF filled, CPL, non-woven, aluminum or steel skins are possible.

EconCore honeycomb cores are available in a thickness range from 3 – 40 mm, with densities of 40 – 120kg/m³ and compression strength of 0.3 – 3.0 MPa. Cell size varies from 3 – 12 mm diameter and customized core and sandwich panel combinations are available on request.

TorHex are small cell honeycomb cores starting from ordinary corrugated cardboard. The small cells of the honeycomb allow for reduction of skin thickness and hence for reduction of panel weight without degradation of surface quality of the panel. In a first production step the cardboard is slit and turned. In a second step in the production line skins are added onto the core. Paper, Kraftliner, MDF or wood skins can be added to realize a finished sandwich panel. Other options are to finish the part with glass fiber, natural fiber or non-woven in combination with PP or PU.

TorHex technology is suited primarily for, but not limited to, packaging, automotive and furniture applications. These panels can be further processed to final parts for automotive or other applications. TorHex honeycomb cores are available in a thickness range from 5 – 15 mm, with densities of 40 – 100kg/m³ and compression strength of 0.3 – 1.3 MPa.
