Colback®Technology

Colback nonwovens are made with bi-component filaments with a polyester core and a specific polymer skin. We tailor the filaments’ polymer skin and core/skin ratio to meet your specific needs.

Thermal bonding - no chemicals or fillers

Our bi-component design creates a set of unique properties. Most importantly, there’s no need for chemical bonding, so Colback is free from formaldehyde. Instead, we thermally bond the filaments’ skins, forming countless connections to give the material its unrivalled performance.

Inlays

Colback technology also means we can add ingredients to meet specific demands – for example, glass scrim and fleeces can reinforce a membrane or increase fire resistance.

Operational efficiency

Colback nonwovens are uniform and have excellent mass evenness. So, as well as complying with building code requirements, they also make processing easy and improve operational efficiency.
