Abstract
The present invention relates to a polyamide moulding compound which consists of a blend of two specific polyamides. The first polyamide is thereby based substantially on 1,5-pentanediamine as diamine component used during polycondensation. The second polyamide is thereby polyamide 6I/6T. The polyamide moulding compounds according to the invention are distinguished by extremely low shrinkage and low differential shrinkage (difference between shrinkage of the moulded article longitudinally and transversely relative to the injection flow). In addition, the present invention relates to moulded articles which are producible from the polyamide moulding compounds according to the invention and also to purposes of use of the polyamide moulding compounds.
