For over 25 years, MP Global Products have been upcycling and repurposing fiber materials that were otherwise deemed as unusable waste from other manufacturing lifecycles. Diverting these fibers from our landfills and consuming them into our patented manufacturing process has been the backbone of MP Global from the very beginning. Because of the material DNA from these recycled materials, our products intentionally control sound transmission, add support, and protect against harmful moisture. While others are trying to define their "green" story, we have been "green" long before it was popular.
