A Lightweight Absorber (LWA) semi-rigid foam for automotive applications

ACOUSTIFLEX® S NBR* polyurethane foam system is a Lightweight Absorber (LWA) semi-rigid foam system designed for acoustic applications in engine and trunk compartments. This new system is fully formulated and includes the mix of a polyol blend with SUPRASEC® diisocyanate and additives for efficient production of acoustic components for the automotive industry. ACOUSTIFLEX® S NBR foam system is thermoformable, boasting superior acoustics absorption and offering greater flexibility to satisfy a range of design needs.

* Self-supporting Non-Burning Rate

Excellent performance, efficient production

• A lightweight, thermoformable semi-rigid foam with improved sound absorption
• Phenolic free
• Enables cost-efficient production with consistent batch-to-batch quality
• Self-supporting, requiring a reduced number of clips for faster assembly
• Consistent acoustic performance and density through the block
• Good flammability characteristics - MVSS 302 and UL-94V0
