Improved filtration efficiency and dust-holding capacity in particle filters for car interiors and pollen filters.
Colback supports your high-performance melt-blown layer, and is easy to process with knife or rotary pleating.
Our polypropylene skin polymers provide the perfect surface for thermal, glue or point calendar bonding. Colback is a highly adaptable backing layer, ideal as a high-performance support in a wide range of cabin air particle filters.
As single filter layer, Colback is a highly effective pre-filter, protecting high-efficiency filters from coarse dust and water droplets. It’s also exceptionally easy to cut and shape, and therefore well suited to most production processes.
Colback’s performance at high temperatures, and its proven flame retardance, make it ideally suited to automotive filtration applications. It’s tested for dimensional stability up to 80° Celsius, so you can be confident of its efficiency as well as safety.
Whatever pleating method you use, Colback is easy to handle. You achieve high pleat stiffness for maximum filtration efficiency. Plus, our patented embossing technology enables you to create deeper pleats with no collapsing, so you have a much greater effective filter area.
A customer said our proprietary nonwoven fabric was best for their filters, but its seams may affect their new production lines. We found a bonding process that eliminated the seams, and so suits their production. The solution offers expansion opportunities for both our customer and for us.Read success story
