The invention relates to polyamide molding compounds with improved scratch resistance, which are constructed from

Transparent polyamide moulding compound

The present invention relates to polyamide moulding compounds which have very low distortion with good mechanical properties. This is achieved by a combination of transparent polyamide with fibrous reinforcing materials and also particulate fillers. The moulding compounds according to the invention are used for the production of any moulded articles, semi-finished products or finished products.

Polyamide moulding compound and use thereof

The invention is directed to a transparent mold made of a polyamide molding material containing at least one polyamide formed from at least one diamine selected from the group of hexamethylene diamine (HMDA), bis-(4-amino-3-methylcyclohexyl)methane (MACM) and/or bis-(4-amino-cyclohexyl)methane (PACM) as well as from at least one dicarboxylic acid selected from the group of isophthalic acid (IPS), terephthalic acid (TPS) and/or dodecanedioic acid (DDS) or from the aforementioned diamines and dicarboxylic acids in combination with lactams and/or &#x3b1;-/&#x3c9;-amino acids.
