Monofilament having chemical durability and dimensional stability, production method and use thereof

摘要

The invention relates to chemically-resistant and shape-retaining monofilaments made from a dual component material with a core-sheath structure, comprising a core of a shape-retaining material and a sheath of a chemically-resistant material, a method for production and use thereof. Said monofilaments preferably find application in demisters, sieves and filters. A preferred method for production is winding a core material with an unsintered PTFE ribbon and subsequent sintering.
