Voith's Magma dryer fabrics are made from hydrolysis-resistant PPS.

Voith has added to its CleanWeave product line with the new Magma and MagmaHigh dryer fabrics. Magma dryer fabrics are made from hydrolysis-resistant PPS which ensures performance in the hottest dryer positions.

Extreme temperatures in some paper machines put dryer fabrics under severe stress and call for special material properties. Hydrolysis-resistant PPS reduces the stress on the fabric, allows service intervals to be properly planned and thus prevents unscheduled machine downtimes, says Voith.

Both Magma and MagmaHigh use the weave pattern that has already proven effective in the CleanWeave product range. The weave structure features low internal void volume, which significantly reduces dirt within the fabric. Due to its relatively low number of yarn crossover points, this compact weave pattern makes surface cleaning easier and ensures constant air permeability. This guarantees that the fabric maintains its air permeability for optimum drying and web running properties over its entire service life.
