Think, create, Elastollan®

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.

Benefits

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

Elastollan®

Elastollan® is the brand name for thermoplastic polyurethane (TPU) from BASF. It stands for maximum reliability, consistent product quality and cost efficiency. Elastollan® can be extruded into hoses, cable sheathing, belts, films and profiles, and can also be processed using blow molding and injection molding technologies. 

This extensive product portfolio, which makes use of a variety of raw materials and formulations, is the starting point for successfully bringing innovative customer projects to fruition.

We thrive on creative ideas and complex challenges – come and talk to us!                                 

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.

Pneumatic tube made of TPU

Elastollan® 1598 A 10 FC 

Elastollan® 1598 A 10 FC is a thermoplastic polyether polyurethane with a unique product performance

e.g.

  • outstanding hydrolysis resistance,
  • excellent burst behavior and
  • significantly reduced creep behavior.

It’s suitable for applications like pneumatic tubes, conveyor belts and elevator straps.

Aerothan bicycle tube and valve made of TPU

The new Schwalbe Aerothan tube

The new Schwalbe Aerothan tube is made of 100% Elastollan® from the valve shaft to the tube. The TPU convinces with outstanding rubber elastic properties and low wearing effects. The tube is fully recyclable.

Elastollan® is the material of choice because of its characteristics like:

  • Outstanding rubber elastic properties
  • Long-lasting with very low wearing effects
  • Extraordinary flexibility and damping properties at different temperatures
  • Recyclability
