Problems printing on polyurethane.

[alansimpson]

I have a molded product that was rushed through production without much thought to printing on company logo. So far printing has come off.
Material is IROGRAN A 75 P 4581 from Huntsman. It is a polyether-polyurethane used for molding and extrusion of cable.
Product is 80mm X 13mm diameter and curved in two directions. See attached picture. Logo is two colour.

Material manufacturers have been no help and I am not sure what printing has been tried.

Can anybody make suggestions apart from starting from scratch with a known print compatible material?

Thanks in advance
