Multi-Extrusion (coex/triex)
Combination of various materials and colours

Multi-Extrusion with two (coex) or three (triex) materials or colours offers many options for design and functionality combinations for not only the lighting sector, but also for technical and POS applications.

BWF Profiles also offers profiles in various colours and materials from a single tool. Mechanically, mono-material combinations - such as that of PC + PC combinations - are formed as a single component since the molecules are bonded across multiple extrusion edges.


  • profile from one tool, no mechanical bonds necessary
  • no adhesive or weld connections necessary
  • points of separation only visual (colour separations)
  • combination of functions
  • low-stress profiles also with multi-extrusion


  • lighting
  • POS and display
  • bus and rail
  • designer lighting
  • seals, reflectors
  • combination of BWF products possible, e.g. a BWF lens with diffusing layer for optimal lighting technology as well as a seal for your current IP requirements
