UTN: polyester, needle punched
Needle-punched polyester with a three-dimensional fibre structure. High load capacity and the widest weight range in the programme. Variants: K1 (standard fibre) and HF (finer fibre for finer filtration at the same weight).
Material and application
Material: Polyester, needle punched
Weights: 40–400 g/m²
Typical processes: turning, drilling, milling, grinding, honing
Standard widths 0.39–1.0 m; widths above 1 m are made to order. Rolls are supplied in lengths from 50 to 300 m, and the core diameter is matched to the holder on your system.
Test standards
Weight is measured to DIN EN 29073.1, thickness to DIN EN 29073.2, tensile strength and elongation to DIN EN 29073.3 and air permeability to EN ISO 9237. Pore size is stated as Bubblepoint (BP) and Meanflow (MF).
All values are averages subject to normal production tolerances. The current datasheet (PDF) is always the reference.
