Heavy density re-bonded polyurethane foam with MLV (polymer) SGM Prime Barrier Mix 6 mm is a premium multi-layer noise barrier from the SGM Prime line. It combines three functional layers into a single high-performance material:

• Face layer — Heavy Mass Loaded Vinyl (MLV) (polymer core) 3 mm for optimal sound blocking across a broad frequency range.
• Inner layer — a high-density rebond polyurethane foam engineered for maximum sound absorption.
• Lower and mounting layer — a pressure-sensitive adhesive backing with siliconized release paper, which facilitates installation and creates a constrained layer damping (CLD) effect to dampen vibrations.

This material provides maximum noise suppression via resonant absorption while maintaining an optimal, minimal thickness.

Thanks to its unique structure and patented technology, SGM Prime Barrier Mix delivers durable and reliable performance even with extreme temperature swings. Note: The material is not suitable for high-humidity areas, as its sound-absorbing layer is permeable to moisture. It is specifically engineered for high sound-pressure zones like the floor, trunk, and wheel arches.
