Low-melt polyaryletherletone (LMPAEK) unidirectional tapes provide outstanding thermal and fire protection, demonstrating their effectiveness through rigorous testing. These tapes are fire, smoke and toxicity compliant with FAR25.853 and meet OSU Heat Release Rate standards. The tapes were tested under ISO 2685/AC 20-135 Change 1, meeting the fireproof criteria. Additionally, they met UL 2596 requirements for battery thermal runaway tests. These tapes are crucial for high-temperature applications showcasing their resilience and safety in both aerospace and automotive applications.

Part of a broader range that includes films and compounds, Victrex LMPAEK materials are valued for their excellent processability and weldability. They offer versatile solutions for complex needs beyond traditional structural parts, such as: thermal runaway and lightning strike protection, heat sinking, and intricate bracketry.

Victrex LMPAEK materials facilitate automation and high-rate production while addressing performance and sustainability challenges. With reduced environmental impact, lower weight and cost-efficiency, they meet the evolving demands of the transportation industry and support innovative design solutions.
