| abstract |
The invention relates to a laser-markable polyamide composition comprising: ⋅ a first phase comprising Sb2O3 and an aliphatic polyamide with an amide density AD1, and • a second phase comprising an aliphatic polyamide with an amide density AD2, wherein AD1 -AD2 is at least 0.01, and wherein the amount of Sb2O3 is between 0.1 and 5 wt %, • a halogen-free flame retardant in an amount of between 1 to 25 wt%, wherein the amount in weight percentage are based on the total amount of composition. The invention also relates to a process for preparing a laser-markable polyamide composition, as well as laser-marked products comprising the composition. |
