TPU as the basis for fabrics, nonwovens, yarns and coatings
Due to its high elasticity and very good mechanical strength, the plastic is suitable for the production of a wide range of materials for the textile industry.
Elastollan is not only convincing for breathable and water-vapor-permeable membranes, but also for highly tear-resistant fabrics, such as those needed in the construction industry. Roof underlays made of Elastollan, for example, are durable and have a particularly high tear strength. In addition, they are characterized by the fact that they are very good for bonding and welding.
Similar properties are also important in the use of Elastollan in medical films. The new opaque film type Elastollan SP 818, for example, combines very high water vapor permeability with good adhesion and processing properties, especially for blown film extrusion.
Also on show at the Techtextil 2019 are Elastollan-coated polyester and polyether fibers, whose uses include processing into UV-resistant, highly flexible fabrics for shading systems or leisure furniture. The fibers are characterized by their flexibility, high mechanical strength and tear resistance.
Elastollan Bondura is a TPU for solvent-based adhesives and extrusion coatings. It can be used as a base polymer for single-component adhesives or in combination with cross-linking agents. Elastollan Hotbond is a TPU for hot-melt adhesives. The melt flow index can be adapted according to the type.
The company also presents the full suite of Freeflex fiber spun from Elastollan TPU. Everything from rigid fibers to soft and elastic material was displayed. Each fiber is able to fulfill different applications e.g. as shoe uppers, apparel and even anti-run tights. Thanks to its stretch and recovery it ensures an impeccable fit. The fibers are also variable in colors and textures and are also easy-care and sustainable.
Also on show is an engine encapsulation with natural fibers from a cooperation with partner Greiner Perfoam GmbH, Enns/Austria, and a lightweight automotive roof frame from a cooperation with IAC Group, Luxemburg. Further exhibits include glass nonwovens for exhaust air treatment of lacquer cabins and glass meshes for the reinforcement of plaster and insulation systems.
