Extremely lightweight for sophisticated components in various markets

Want to save weight while protecting the environment?  The solution is Lightweight TPE. Applications in the industrial, automotive and consumer sectors benefit from a lower carbon footprint and increased energy efficiency


Weight reduction up to

  • 35 % compared to standard TPS
  • 30 % compared to TPV
  • 50 % compared to PVC



  • Adhesion to polyolefinic materials (e.g. PP, TPV, TPS) in injection molding and coextrusion (LW/UV Series)
  • Excellent compression set
  • Reduced shrinkage and warpage of parts
  • Closed and uniform surface structure
  • Matted surface
  • Compounds available in black colors, natural and precolored variants possible



  • Exceptionally well-suited for sealing applications: unique compression set comparable to EPDM
  • Ideal for automotive applications
  • Power tools, in aviation or with drones
  • Diverse application possibilities in sports and leisure articles such as protectors of all kinds
  • Ski and cross-country skiing equipment or travel accessories  
  • Thick-walled, lightweight components possible
  • Well suited for sealing applications

Specific MATERIAL PROPERTIES for the Automotive Sector


  • Thoroughly tested for UV- and weathering resistance
    • 2 year-cycle Florida testing (PV3930): passed
    • 2 year-cycle Kalahari testing (PV3929): passed
  • 35 – 90 Shore A while maintaining an excellent compression set 
  • Reduction of cycle time in injection molding is possible
  • Self-lubricating modification as a substitute for lubricant varnish

Do you have a question?

You might find your answer here, among the most frequently asked questions about Lightweight TPE:

How do the light weight grades perform vs flame retardancy? For e-mobility possible requirements etc.

Some of the grades are already tested according to UL94 HB and passed successfully. Therefore listing would be possible on request.

What are the deciding technical properties other than light weight we need to consider for exterior seal application when we choose between EPDM and TPE?

Beside the weight factor properties like CS, long term relaxation, noise absorbtion, wheathering resistance are deciding properties. Our LW TPE shows especially advantage in terms of more cost effective process, easier & better bonding to Corner Molding TPE and recycling possibilities.
