EconCore has developed new honeycomb cores for laminated sandwich panels made with SABIC’s NORYL GTX resin. The new honeycomb core is designed to provide higher heat performance, better dimensional stability and lower water absorption compared to honeycomb structures made with traditional thermoplastics. SABIC says the new core material can be used in EV applications and, when combined with thermoplastic composite skins to produce an all-thermoplastic sandwich panel, can facilitate recycling.
“We turned to SABIC for expert assistance in enhancing our honeycomb cores with high-performance thermoplastics to expand our product’s use in a range of applications and overcome the limitations of incumbent materials,” said EconCore COO Tomasz Czarnecki. “We have been impressed with NORYL GTX resin’s ease of use in conversion and appreciated the fact that it works well in our existing equipment. We believe its well-balanced properties will allow honeycomb cores to be used more widely in transportation, clean energy and e-mobility applications.”
SABIC’s NORYL GTX resin provides heat resistance up to 240° C (465° F), with conductive grades that may be used in powder-coated automotive body panels. SABIC is also developing a new grade with extreme low-temperature impact performance for potential use in honeycomb cores for EV battery protection.
