CHEMICALLY RESISTANT THERMOPLASTIC COMPOSITIONS |
摘要 |
The present invention relates to a thermoplastic composition comprising: a) a polyamide component comprising at least three amide monomer units and b) a stabilizer characterized in that at least one of the at least three amide monomer units is an aliphatic amide monomer unit having a carbon to nitrogen ratio (C/N) equal to, or above 6.5, in that at least two of the at least three amide monomer units are semi- aromatic amide monomer units which polymerized provide at least one semi-crystalline semi-aromatic polyamide having a melting temperature of at least 290 °C as measured by DSC at a heating rate of 10°C/min according to standard ISO 1 1357-3 (2009), and in that the amount of aliphatic amide monomer unit is in the range from 20 to 60 wt. % relative to the total weight of the at least three amide monomer units in the polyamide components and the total amount of semi-aromatic amide monomer units is in the range from 40 to 80 wt. % relative to the total weight of the at least three amide monomer units in the polyamide components and characterized in that the stabilizer is chosen from a copper-containing stabilizer, an iron-containing stabilizer and a stabilizer containing copper and iron. |
