Envalior received two top honors at the Society of Plastics Engineers (SPE) Automotive Awards in Bonn, Germany – the Grand Innovation Award for “Most Innovative Use of Plastics” and 1st Place in “Enabler Technology”, recognizing its leadership in sustainable, high-performance lightweighting solutions.

Grand Innovation Award for “Most Innovative Use of Plastics”: Lightweight roof cap

Envalior’s contribution to the development of a lightweight roof cap for a premium German automotive convertible, manufactured by Röchling Automotive, has been recognized with the Grand Innovation Award.

Lightweight, high-performance roof crossmember made with Durethan and Tepex materials, integrated at the front of the convertible’s fabric roof for strength and design flexibility.

The roof cap was developed through close collaboration between Envalior, Röchling Automotive, and the German automotive OEM. It combines Envalior’s materials expertise with Röchling’s advanced manufacturing and the OEM’s demanding design requirements, resulting a lightweight, high-performance solution that meets stringent safety and aesthetic standards.

Additionally, the new roof cap is fully recyclable, aligning with upcoming European Union End-of-Life Vehicle Regulation (ELVR), which sets ambitious recyclability and recoverability targets for new vehicles.

“The roof cap sets new standards in an area where plastics were previously unthinkable. We are proud to have received this award together with our partners and are convinced that lightweight, sustainable composite solutions will be an integral part of future automotive series,” said Dr. Klaus Vonberg, Sales & Project Manager for Tepex at Envalior.

First Place in “Enabler Technology”: Hybrid composite battery cover

Envalior received another award, the 1st Place in “Enabler Technology”, with a collaborative project on hybrid composite battery cover with SABIC, Siebenwurst, Ensinger, and Forward Engineering.

Hybrid composite battery cover.

The innovative design features a sandwich architecture composed of two Tepex Dynalite PP-glass fiber laminates and a flame-retardant, fiber-reinforced core. This configuration delivers low weight, improved heat management, enhanced safety, and greater cost efficiency, helping extend EV range and performance.
