High Flow TPE Compounds

We’re bringing novel technology to the polymer industry with Dryflex HiF, a family of very high melt-flow TPS-SEBS compounds. They are part of our portfolio of next generation materials for automotive interiors. They were developed primarily for injection moulded panels and skins, but could also be used in other application areas where very high flowing materials are needed.
Dryflex HiF - High Flow TPEs

Key Facts About The Technology

Dryflex HiF TPE skin on PP carrier backfoamed with PU
  • High-Flow and scratch-resistant TPS-SEBS compounds with hardness 70-90 Shore A
  • Further development of KRATON IMSS™ Technology
  • 1K : Skin moulding with subsequent back foaming
  • 2K : Direct overmoulding of PP carriers
  • Helps to meet sustainability targets due to recyclability in processing, lower density & low fogging
  • Lower systems costs compared to PVC slush, PU and foil processes
