The compacting principle (one pack)

    Compacting is the agglomeration of a homogeneous mix of powders by melting one of the additives (the binder). This melting is carried out by applying pressure to the mix on the draw-plate.

     The main advantage of compacting (one pack or blend) is the absence of polymer in the final formulation.

This presents the following advantages :

  • Reduction of the final cost
  • Improvement in productivity
  • Improvement of work and safety conditions (no handling of powder and absence of dust)
  • Increased proportioning accuracy resulting from a constant ratio of the various additives
  • Possibility of incorporating liquid additives
  • Constant and regular feeding
  • Good dispersion within the polymer during transformations.

     Polytechs' goal is to implement the formulations of each of our customers. It is a service that we offer solely as toll compounding.

      For complex formulations, Polytechs offers an alternative by carrying out this time of mixture by extrusion

      Just as is the case for any toll compounding given to Polytechs, customers may freely choose their additive suppliers.
