Think, create, Elastollan® (TPU)

Thermoplastic Polyurethane

Elastollan® is the brand name for thermoplastic polyurethane (TPU) from BASF. Over the last few decades, the numerous benefits of Elastollan® in all its forms – aromatic or aliphatic, very soft or glass fiber-reinforced, flame retardant or highly transparent – have been clearly demonstrated across every sector of industry.


Key Advantages of Elastollan®

  • High wear and abrasion resistance
  • High tensile strength and excellent tear resistance
  • High resistance against oils, greases, oxygen, and ozone
  • Very good low-temperature flexibility
  • Very good damping capacity

Focus topic: Plastics for wallbox applications

If you want a relaxed drive with your electric car, you better have a charging station at home. Function and safety are decisive criteria here, but optics and design are also becoming more and more important. In the Wallbox Demonstrator, BASF is showing some plastic materials that are ideally suited for certain application points in a wallbox and that cover the high requirements in the wallbox sector particularly well thanks to their product performance.

Wallbox RSW Teaser

Elastollan® RSW

The material combines properties such as abrasion resistance and flame retardancy in ideal balance with mechanics, usability and flexibility over a wide temperature range while offering strong UV, weather and ozone resistance.

The Ultramid® shows low distortion and offers very high mechanical strength. The material achieves the UL94 HB flame retardant classification.

Ultramid® B3GK24 RSW

Ultramid® Ultradur® FlameRet RSW

Based on non-halogenated flame retardant additives, both materials have a UL94-V0 flame retardant classification and are easy to color. The low content of halides counteracts contact corrosion.

More about Ultramid® and Ultradur®

A special polyamide for high-gloss components without additional coating. The material shows high resistance to scratches, chemicals and UV.

Ultramid® DeepGloss RSW

Ultramid® Vision RSW

The first semi-crystalline and semi-transparent polyamide that allows light to pass through largely unhindered. The polyamide combines chemical, temperature and scratch resistance with colorable transparency.

New mobility concepts require innovative materials. 

Charging cables for electric vehicles also need cable sheathings ensuring a strong resistance to UV, weather, ozone and microbes. In order to make the charging process safe, cables should be made flame retardant without halogens, must be able to form a coil and must be flexible. Elastollan® is perfect for this complex requirements profile. Elastollan® further sets itself apart from other materials by being recyclable.

Elastollan® features an extraordinary property profile combining elasticity with resistance over a wide range of temperatures. It is abrasion- and impact-resistant, has a good elastic recovery, is tear and kink-resistant as well as oil- and grease-resistant. Moreover, Elastollan® can be modified for specific applications, by glass-fiber reinforcement, for instance.
