The Powder Injection Molding (PIM) process provides the ability to manufacture a wide variety of materials with mechanical properties that are near equivalent or in some cases exceed machining or cast process.

The binder system comprises of three different components

LOXIOL® 3172, typically 25 – 35 w% of the binder

Thermoplastic polymer (special co-polyamide) as backbone

  • Polyamides provide a high material strength, which is beneficial for green and brown part stability
  • Polyamides are polar materials and thus provide strong interaction to polar particle surfaces

LOXIOL® 2472, typically 60 – 70 w% of the binder

  • Solid plasticizer, later removed in solvent debinding
  • Lower processing temperature of polyamide
  • Adjustment of binder characteristics such as rigidity and flow by ratio of polymer to plasticizer

LOXIOL® G 20, typically approx. 5 w% of the binder

  • Stearic acid as Release Agent


Binder formulation and binder-to-powder ratio can and should be adjusted according to the powder used. The higher the specific surface of the powder (lower particle size, water- vs. gas-atomized powder), the higher the plasticizer share in the binder and the higher the binder share in the feedstock.

The binder share in the feedstock is typically 35 – 40 % by volume.

Guide formulations can be provided upon request.

Assets of the Emery Oleochemicals Binder System

  • Superior green and brown part strength; mechanical post-treatment in green state feasible
  • Highest dimensional accuracy thanks to high powder loading and low shrinkage as well as low temperature solvent debinding
  • A binder system made by experts in optimization of polymer processing
