Elastollan® (TPU) for film membranes, nonwovens, textile coatings and adhesives
Flexible films made from Elastollan® not only look appealing, but they also protect, seal and provide adhesion. Elastollan® has a versatile set of properties so that it has numerous possible applications.
Outstanding elasticity means that the thermoplastics polyurethane (TPU) Elastollan® is particularly suitable for producing mono- and multi-filaments, as well as for coating polyester and glass fibers used for shading systems and covering chairs.
Elastollan® can also be worked into nonwoven fabrics using the melt blown as well as spun bond techniques. For these applications, particular importance is placed on product benefits such as elasticity of up to 500 %, high rebound and adjustable gas permeability.
In textile membranes and medical membranes, Elastollan® offers high water-vapor permeability whilst still being wind- and waterproof, combined with good elasticity.
Even without the use of additional additives, the unique morphology of Elastollan® grades SP 806 and SP 883 produces a matte, non-blocking film surface. It is characterized by a low surface tension and very good adhesion to the substrate. The surface is particularly skin-friendly, which is vital for medical applications among others.
Elastollan® Hotbond is a TPU for melt adhesives. The melt flow index can be adapted to the individual classes.
