Application Description

Technical textiles demonstrate their strengths in a variety of different industrial applications. For instance, in emery paper manufacturing velours are laminated to the reverse side of paper. The material compound is then rolled and stored for approx. 24 hours, after which it is die cut and packaged.
Generally applied by slot nozzle or roller systems, laminating adhesives promote highly efficient manufacturing processes and the properties of the end product. Emery paper is exposed to high mechanical stress and heat during use and therefore the adhesive has to facilitate a high compound strength. The separate layers must remain bonded together until all the abrasive has been worn down. Therefore, PUR hot melts which are characterised by very high initial strength and optimum adhesion to resinated papers are the adhesive of choice for laminating emery paper. These properties already play a crucial role immediately after laminating and ensure optimum resistance in downline processing.
Filter media are also manufactured from a laminated material compound and activated charcoal bonded to the textile. The laminated layers must promote the absorption capacity and the permeability of the product which is a critical demand for filter media. Thermoplastic PO and reactive PUR hot melts provide high compound strength with minimal adhesive application amounts.
