BASF Elastollan® S90A Polyester Type Polyurethane Elastomer

Subcategory: Elastomer, TPE; Polymer; Polyurethane, TP; Thermoplastic

Key Words: TPU Rubbers

Material Notes:
Processed by extrusion or injection molding. Elastollan S series of products are polyester-based thermoplastic polyurethanes that exhibit good hydrolytic stability. They also exhibit good oil, fuel and solvent resistance. These products can be injection and blow molded and extruded.

As with all TPU products this grade must be dried prior to processing.

Property values below are typical values based on test samples cured 20 hours at 100°C before testing. Information provided by BASF Corporation.
