What’s your process?
Elastollan® TPU is as versatile in its processibility as it is in its performance characteristics. Blow molding. Calendering. Extrusion. Injection molding. Each process has its own purpose and best-practices, and Elastollan can help maximize productivity while delivering the high-performance properties you need to make your product better.

A common process that manufacturers use to produce hollow parts or products is known as blow molding. BASF's Elastollan TPU is ideal for this process because of its superior melt strength, easy processibility and excellent demolding properties.
After Elastollan is extruded as a film or sheet, it can be further smoothed and flattened by calendering. This involves passing the extruded Elastollan through a series of hard rollers, called "calenders," which are often heated and usually made of cast iron or steel.
Elastollan products can be successfully used in the extrusion process to make various forms such as hoses, tubes, cables, belts, films, sheets and more.
Injection molding is a commonly used process for manufacturing products that have complex geometries. It uses high pressure to inject melted Elastollan into a metal mold, which gives the final part or product its shape.
