SCHWARZENBACH - Sandler has launched bluefiber, a new brand of acoustic nonwovens products made from 100% polyester.

Bluefiber products are made to a large extent from recycled PET bottles, and as a single polymer, are also easily recyclable themselves. They are odorless and, in contrast to other fibrous materials, do not pose health risks to workers and users alike.

According to Sandler, smart acoustic polyester also has additional advantages over other materials; it is resistant to ageing and to various environmental influences.

Bluefiber products are therefore durable and, owing to their open-pore structure, efficiently dampen sound – free of harmful substances and entirely without chemical additives. As the nonwoven is fully recyclable, even after many years of use, the material can be reprocessed and fed back into the production process keeping the use of new resources to a minimum.

In comparison with wood or other fibrous materials, polyester is also considerably lighter, the fibers are more resistant to breakage, and thus the products are easier to handle. bluefiber products are flame-resistant and tested according to EN 13501.

"Owing to their excellent sound absorption properties the lightweight textile materials offer an ideal basis for individual interior design concepts, creating a pleasant living space," Sandler said. "Self-supporting panels and pads in different thicknesses, performance types and color versions; flexible roll goods, optimally adaptable to component contours; or custom-made solutions for your specific application: bluefiber products are ready to use, combining function and design."
