ANTI-YELLOWING POLYAMIDE COMPOSITION |
摘要 |
The invention relates to a polyamide composition with an improved resistance against yellowing. The invention also relates to a shaped article made from the composition and to a method of forming such a shaped article. The polyamide composition comprises:
a. 90 to 40 wt% of one or more semi- aromatic polyamides and
b. 10 to 60 wt% of one or more of aliphatic polyamides and
c. Optionally one or more secondary components,
wherein the sum of the amount of semi-aromatic and aliphatic polyamide is 100wt% and wherein:
i. the semi-aromatic polyamide is derived from one or more aliphatic diamine monomers containing 4 to 12 carbon atoms and one or more benzene dicarboxylic acid monomers and
ii. the aliphatic polyamide is derived from one or more aliphatic diamine monomers containing 4 to 10 carbon atoms and one or more aliphatic dicarboxylic acids with 6 to 12 carbon atoms with the proviso that no additionally thermally conductive material is present in the composition. |
