A polyamide composition contains a) 88.5-98 wt. % of at least one aliphatic polyamide, wherein at least one monomer unit has 10 to 14 carbon atoms, and wherein the aliphatic polyamide is semi-crystalline; and b) 2-11.5 wt. % of an S glass fiber. The weight percentages of a) and b) are based on a total weight of the polyamide composition. The polyamide composition contains neither a polyolefinic impact modifier nor a core-shell modifier. A moulding material containing the polyamide composition is useful, and a moulded article can be produced from the moulding material. A shoe outsole containing the polyamide composition is also useful.

Polyamide composition

A plastic material is useful as an ink receiver or printing medium in dye diffusion thermal transfer printing, wherein the plastic material has a polyamide component (a), and a (co)-polyamide (b) based on ether units and amide units. This plastic material can be used to make a layered structure. The layered structure can be used in dye diffusion thermal transfer printing. A security and/or valuable document with the layered structure can be obtained. Based on the finding that the (co)-polyamide (h) offers sufficient absorbency for the printing ink, the layer produced from the plastic material can be printed on by means of dye diffusion thermal transfer printing with a good color intensity.

Plastic material for printing by dye diffusion thermal transfer printing

A polymer composition includes a linear aliphatic polyamide having on average 10 to 14 carbon atoms in the monomer units, an S glass fibre, and a polyolefinic impact modifier. The polymer composition can achieve higher stiffness and impact strength without impairing the ductility. The polymer composition can be used as a moulding material.

Polymer composition based on linear aliphatic polyamide

A polymer composite includes a linear aliphatic semi-crystalline polyamide having on average 10 to 14 carbon atoms in the monomer units, or the compound thereof, an S glass fiber, and a core-shell impact modifier. The polymer composite can achieve higher stiffness and impact strength without impairing the transparency significantly. The polymer composite can be used as molding material.
