Latest Patents
One of Lehnert's latest patents is focused on a filter medium. This invention relates to a method for the manufacture of a multilayered filter medium whose air permeability is at least 500 l/msec. The multilayered filter medium produced by this method, when charged with 5 mg/cm² SAE-dust of the class 'fine', exhibits a pressure increase of no more than 100 Pa. Another significant patent is for a laminate with improved properties. This invention describes composites made from at least two plies, where one of the outer layers comprises glass fibers, specifically a staple glass fiber nonwoven. The layers are bonded through needling, allowing some fibers of the organic nonwoven to emerge from the surface of the glass fiber sheet. The composite is then treated with a binder using a rotating roll for single-side application to the glass fiber surface. These composites are particularly suitable for producing bituminized prefabricated roofing and waterproofing sheets, as well as backings for coatings like PVC coatings.
