SLX OptiForm® – The new DUST-FREE pink material for plug assist

OptiForm® SLX is a plug assist material wich combines the toughness of engineering thermoplastics with the low thermal conductivity of a syntactic foam.

OptiForm® SLX eliminates machining dust compare to the standard FLX material but with a similar finish.

The formulation has been designed to minimize chilling of the sheet and improve plug/sheet interaction to get the best thickness distribution and high transparency.

OptiForm® SLX   gives a very smooth finish surface.

OptiForm® materials are DUST FREE during machining, finishing, and cutting.

For PET Thermoformed parts:

  • Productivity + 5 % to 35 %
  • Reduce Thickness -3 to 15 %

OptiForm® SLX may be used in a wide variety of applications on sheet-fed, rotary, or in-line machines. With PET or PP we will give better productivity than any other epoxy syntactic. OptiForm SLX is ready to replace other  syntactic materials such as Hytac® FLX and avoid dust in your workshop and your CNC machine.
