Acoustic Felt has been designed for the acoustic contractor, from 100% polyester
Acoustic felt is made from Polyester. It is made from a chemical base called polyethylene terephthalate, or PET for short. PET can be found in many plastics that are used on a daily basis, including plastic water bottles. It is completely recyclable.
Because P.E.T acoustic felt is made from 100% polyester, warm water and soap can be used to remove any stains.
