The Clever Combination of Two Polymer Components

Thermoplastic elastomers (TPE) combine the properties of thermoplastics and elastomers. For example, TPE exhibits elastic behavior at room temperature (comparable to classic elastomers), but can be shaped plastically when heat is applied (thermoplastic behavior).

TPEs are copolymers consisting of a hard and soft segment, which are used either as random or block copolymers. The properties of the thermoplastic elastomers can be specifically adjusted by the segments used and their quantity ratio to each other. As a result, they exhibit excellent mechanical properties with high flexibility and good chemical resistance.

A special position among the thermoplastic elastomers is held by TPE-U's (PUR cables), which have a particularly high tear resistance, very good low-temperature flexibility and good hydrolysis resistance. They are therefore ideal for use in moving applications.

The areas of application for TPE are wide-ranging:

  • Robot cables
  • drag chain cables
  • railroad cables
  • Special cables (hybrid cables)
  • Military cables (navy/air force)
  • Charging cables for e-vehicles
