Semi-crystalline copolyamides, moulding compounds comprising same and their use, and mouldings manufactured from same

The present invention relates to polyamide moulding compounds that contain a semi-crystalline copolyamide, at least one filler, and optionally additives. The invention likewise relates to mouldings manufacture from these moulding compounds and to the use of the moulding compounds to manufacture mouldings.

Polyamide moulding compound and its use and mouldings manufactured from the moulding compound

Disclosed are polyamide moulding compounds having a relative permittivity of no more than 3.5 at 2.45 GHz, and having the following components: (A) 25 to 80% by weight of a mixture made of at least one partially crystalline aliphatic polyamide and at least one amorphous or microcrystalline polyamide, (B) 20 to 65% by weight of at least one glass filler, and (C) 0 to 10% by weight of additives, the sum of components (A), (B) and (C) producing 100% by weight. The polyamide moulding compounds are for use in components of devices such as laptops and mobile phones.
