Patent ID: 8859652

Claim:
A flame-retardant polyamide molding material for sheathing optical waveguides and optical cables, wherein the polyamide molding material is composed of: (A) 40 to 71 wt.-% copolyamide MACMI/12; (B) 20 to 51 wt.-% of at least one aliphatic polyamide; (C) 6 to 20 wt.-% melamine cyanurate; (D) 3 to 10 wt.-% aryl phosphate; and (E) 0 to 6 wt.-% further additives; wherein the components (A) to (E) add up to 100 wt.-% of the polyamide molding material, wherein the copolyamide MACMI/12 has a laurin lactam content of 23 to 45 mol-% in relation to the molar sum of the monomers MACM, isophthalic acid, and laurin lactam of this copolyamide, and wherein the isophthalic acid in the copolyamide MACMI/12 can be entirely or partially replaced by terephthalic acid.
