摘要： Flame-retardant polyamide molding material for sheathing optical waveguides/cables, includes: (A) 40-71 wt.-% copolyamide MACMI/12; (B) 20-51 wt.-% of at least one aliphatic polyamide; (C) 6-20 wt.-% melamine cyanurate; (D) 3-10 wt.-% aryl phosphate; and (E) 0-6 wt.-% further additives. Components total 100 wt.-% of polyamide molding material. Copolyamide a MACMI/12 has laurin lactam content of 23-45 mol-% in relation to molar sum of monomers MACM, isophthalic acid, and laurin lactam of this copolyamide. Isophthalic acid in copolyamide MACMI/12 can be entirely/partially replaced by terephthalic acid. Test specimen produced from this polyamide molding material has Shore hardness D of at least 77, and buckling test using PA12 extrudate coated with this molding material is passed upon winding around metal rod having 12 mm diameter. PA12 extrudate for buckling test has diameter of 1.5 mm and coating 0.7 mm thick. Optical waveguides/cables sheaths made of this polyamide molding material have bite-inhibiting effect in relation to rodents.
