Monadnock Non-Wovens (MNW), a leader in the manufacture of melt-blown polypropylene (MBPP) roll goods, has announced the official trademark registration of its next generation of sound attenuation media – HPAM (High Performance Acoustic Media).
Leveraging its manufacturing experience and long history of partnership with the automotive industry, MNW designed and developed HPAM to improve sound absorption at lower frequencies through an enhanced fibre matrix and a tunable scrim on both sides.
With this tunable scrim, Monadnock HPAM is said to provide excellent sound absorption and address the challenges of meeting or exceeding both acoustical targets and weight reduction targets for all vehicle types – including steel, aluminium or composite bodies with internal combustion, hybrid, or electric engines.
“We are pleased that HPAM is now a registered trademark and the product is already approved by most major car manufacturers,” said Monadnock Managing Director Keith Hayward. “HPAM is suitable for use in all types of appliances, automobiles and even large trucks and farm vehicles.”
As with all MNW products, HPAM is made with 100% renewable electricity through the purchase of Green-e certified renewable wind power energy certificates. Constructed with 100% virgin polypropylene, HPAM is lighter than competitive products – critical for fuel economy, and it is fully recyclable at the end of its useful life, the company reports.
Monadnock Non-Wovens was established in 1999 to manufacture nonwoven material for the fast-growing filtration, facemask, healthcare, automotive, appliance and consumer markets. It supplies nonwoven roll goods media to converters around the world using advanced fibre technology to meet global standards.
