Abstract
Thermoplastic, flame-retarded plastic moulding compounds with improved mechanical properties, in particular for LDS applications, are described. The thermoplastic moulding compound consists of: (A) 21-81.9 wt. % thermoplastic material, consisting of (A1) 55-100 wt. % polyamide, containing at least 50 wt. % partly aromatic, partly crystalline polyamide; (A2) 0-45 wt. % non-polyamide based thermoplastic material, wherein (A1) and (A2) add up to 100 wt. % component (A); (B) 10-70 wt. % glass fibres; (C) 0.1-10 wt. % LDS additive or a mixture of LDS additives; (D) 8-18 wt. % halogen-free flame retardant; (E) 0-40 wt. % particulate filler, different from (C); (F) 0-2 wt. % other further additives; wherein the sum of (A)-(F) makes up 100 wt. %.
