Freudenberg Performance Materials, Low & Bonar and Filc shared details of their latest technical textile solutions together for the first time since their merger in 2020 at the recent IDEA nonwovens show in Miami (March 28 to 31).

With Evolon RE, Freudenberg presented an even more sustainable version of its high-performance microfilament textiles. Evolon RE is manufactured from an average of 70% recycled polyester, which the company makes by recycling post-consumer PET bottles in-house. It is available for various applications, including high-tech wiping and technical packaging, in weights currently ranging from 80-300gsm.

Colback Plus is a pleatable medium with a built-in filtration capacity layer for use as a carrier in the manufacturing of cabin air, room air and HVAC filters. The well-known performance characteristics of Colback support media – ensuring low pressure drop and high pleat stiffness – is combined with a unique fine fibre technology, creating new capabilities for manufacturing and added value for customers.

Dripstop for simple and economical condensation control in metal roofing. © Freudenberg

A new panel with Dripstop, an anti-condensation membrane, provides a simpler and more economical way of controlling condensation in metal roofs.

When the temperature and humidity conditions reach the dew point, moisture condenses on the underside of an uninsulated metal roof. If there is a lot of condensation, drops of water form. The traditional method for dealing with condensation is to try and insulate the roof so that the temperature on the panel never reaches the dew point. The roof panel provides a medium for trapping this moisture in the membrane’s specially designed pockets. Dripstop holds that moisture until conditions go back below the dew point and it is released back into the air in the form of normal humidity.
