Abstract:
The invention relates to a polyamide composition comprising: a. A semi-crystalline polyamide; b. An impact modifier in an amount ranging from 1 wt % to 50 wt %; c. A branching agent in an amount ranging from 0.01 to 6.0 wt %; d. An inorganic stabilizer in an amount ranging from 0.01 wt % to 2.0 wt %; e. An organic stabilizer E1 comprising a primary antioxidant group in an amount ranging from 0.01 wt % to 2.0 wt and an organic stabilizer E2 comprising a hindered amine group in an amount ranging from 0.01 wt % to 4.0 wt %; or an organic stabilizer E3 comprising a primary antioxidant group and a hindered amine group in an amount ranging from 0.02 to 6.0 wt %; or a combination of E1, E2 and E3 in a total amount of 0.02 to 6.0 wt %; wherein all wt % are based on the total amount of polyamide composition. The invention also relates to a process for preparing a container by blow molding this composition, as well as use of the container in various applications.
