Premiere for Elastollan TPU as laminate films for printing on textiles
Techtextil, the international trade fair for technical textiles and nonwovens in Frankfurt, was the platform for BASF to present a new application for its well-known Elastollan TPU.
Due to its high elasticity and mechanical resilience, the thermoplastic polyurethane is well suited for the production of various basic materials in the textile industry. For the first time, BASF demonstrated Elastollan used as laminate films for printed textiles. For this application especially, the material offers a broad range of advantages: Apart from very good material adhesion and wash and abrasion resistance, it also has very good printability even for complex contours.
Elastollan is suitable for breathable and water-vapour permeable membranes and also for particularly tear-resistant fabrics, for example, in the construction industry: roof linings made from this TPU are durable and show particularly high tear propagation strength. Moreover, they provide good adhesiveness and weldability under lathing and tiles. In textile and medical membranes, the TPU offers high water-vapour permeability. Polyester fibres coated with Elastollan can be processed, among other things, into UV-resistant and flexible fabrics for shading systems as well as outdoor furniture.
BASF introduced two new products at the trade fair:
- Elastollan Bondura, a TPU for adhesives that contain solvents 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 melt adhesives. The melt flow index can be adapted depending on the precise type.
