ThermHex and Gubesch are one of the TecPart innovators
At October 8, 2025, ThermHex Waben received the TecPart Innovation Award together with Gubesch Group at the K – The World’s No.1 Trade Fair for Plastics and Rubber in Düsseldorf for the super-lightweight underbody panel constructed for the Porsche 911.
The panel is at least one kilogram lighter than the previous series without compromising on mechanical properties. The new underbody component comprises a ThermHex Waben GmbH sandwich panel with a hexagonal honeycomb core made of polypropylene (PP) and cover layers made of PP with glass fiber reinforcement.
Compared to the previous LWRT component, the new honeycomb sandwich semi-finished product from the patented ThermHex production process does not use glass fibers in the core, but only in the load-bearing cover layers. The new underbody panel, consisting of three components, now weighs exactly 1.2 kg less and has passed all hardness and durability tests at Porsche.
“We would like to thank our partner Gubesch for the trusting and pleasant cooperation and look forward to further developments”, remarks Dr.-Ing. Jochen Pflug, CEO of ThermHex Waben GmbH.
