PolySorb is manufactured from 100% polyester with up to 56% post-consumer recycled content. PolySorb itself is 100% recyclable and environmentally friendly.
PolySorb provides ambient sound absorption where acoustical control is critical. With excellent sound absorption and a 0.9 average NRC value PolySorb is ideal for dealing with and fixing sound issues.
PolySorb is harmless to the atmosphere and human body. There are no carcinogens which make this product excellent for “clean room” environments like hospitals and around technology equipment. PolySorb is 100% formaldehyde free.
PolySorb is water-resistant and if exposed to water no coloring will occur. PolySorb won’t weather when exposed to air over long periods of time. Over time PolySorb won’t disperse due to weather.
