MSA - Wool Bag ECR-glass

Offer - Marine Industry


MSA-Marine Sound Absorber ECR-glass
Perfect silencers absorber filled into acoustic properties PP bags.

Volume and perfect open glass fiber filled into PP bags. Begs melts in early beginning and fiber expands into silencers chamber. Glass fiber is a perfect absorber material as well as thermal insulation material. It is also very flexible that gives warranty that fiber will not be accumulate only on the bottom of chamber.

Advantages of using bags

  • Guaranty weight of insulation per muffler is the same in each one, so noise reduction of each muffler is replicate and controlled.
  • Significantly reduced time of muffler production process; labor consuming is lower and reduces costs
  • That is all well environmental solution (no flying fibers, no WASTE) during muffler assembly
  • Glass fibers absorbs 3-4 times less water than mineral wool – lower corrosion of the muffler
  • There is no “flying” all around fibers on the production line – operators has only contact with polyethylene/polipropylene bag delivered in paper cardboard
