HPAM®

HPAM High Performance Acoustic media is a nonwoven NVH (noise, vibration and harshness) solution offering improved sound absorption at lower frequencies in all types of appliances, automobiles and even large trucks and farm vehicles.

 

  • Details

    HPAM media significantly improves sound absorption at lower frequencies through an enhanced fiber matrix and a tunable scrim on both sides.

    With this tunable scrim, Monadnock HPAM provides excellent sound absorption and addresses the challenges of meeting or exceeding both acoustical targets and weight reduction targets for all vehicle types – including steel, aluminum or composite bodies with internal combustion, hybrid, or electric engines.

    HPAM is suitable for acoustic control in all types of appliances, automobiles and even large trucks and farm vehicles.

    For environmentally conscious industries, HPAM is made with 100% recyclable polypropylene.

    Our Validation Guide is available on request.
