UTH: polyester, high density
Dense polyester spunbond for fine filtration. Low air permeability and small pore size give efficient particle capture in precision machining.
Material and application
Material: Polyester spunbond, high density
Weights: 30–70 g/m²
Typical processes: grinding, honing, lapping, fine wire drawing
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.
