Pinneberg/Germany, September 20th, 2018 - The new ROMILOY® PA/PP blends have polyamide to thank for their good mechanical properties, and the polypropylene reduces the inherent water absorption of the polyamides, leading to a greater dimensional stability. In a direct comparison with polyamide 6, the new ROMILOY® PA/PP blends already have higher notched bar impact strength even at dry-as-molded state and offer a constant mechanical properties profile after conditioning. What’s more, polypropylene reduces the density of the products and thus the volume consumption and costs for the user.
Strictly speaking, the two products polyamide and polypropylene are incompatible, i.e. cannot be mixed. However, thanks to ROMIRA’s recipe and process know-how it has been possible to mix and distribute the two phases homogeneously and stably.
The new products will be used wherever the good properties of polyamide are needed, but without any losses through the absorption of water. Examples include sports equipment, in particular ski bindings, as well as the automotive, industrial and electronic sectors.
