What is Orgalloy®
Immiscible blend of Polyamide
and Polyolefin
•Bad mixture of the 2 materials.
•Poor performance.
3
Polyamide 6 or 6,6 based alloy
with a dispersed polyolefin phase
• Intimate mixture of materials.
• Compatibilizers guarantee the morphology
and a constant level of performance.
• Stable over multiple processing runs.

Orgalloy®: unique synergies
● PA matrix: Excellent barrier performance to HCs and apolar components.
● PE phase: Good barrier performance to polar components.
Orgalloy® “alloy-technology”: permeation is lower than blend/mixture of
PA6/PE. This is the “nanocomposites” synergetic effect of alloys.
