Abstract
Disclosed is a fluid transport pipe which has an inner layer, coming in contact with a fluid, comprising at least one aliphatic polyamide and at least one impact modifier and also at least one outer layer which is connected directly to the inner layer and is formed from an aliphatic polyamide and at least one flame retardant. While the inner layer ensures the chemical resistance relative to the fluids to be transported and the mechanical resistance, the flame resistance is ensured by the outer layer.
Claims17
A fluid transport pipe, comprising
- an inner layer, coming in contact with a fluid, formed from a moulding compound comprising at least one aliphatic polyamide and at least one impact modifier, the at least one polyamide having an amine end group concentration of 30 to 90 mmol/kg, and selected from the group consisting of PA12, PA11, copolyamides, mixtures, and blends thereof and
- at least one outer layer, connected directly to the inner layer, formed from a moulding compound comprising at least one aliphatic polyamide selected from the group consisting of PA12, PA11, copolyamides, mixtures, and blends thereof, having at least one flame-retardant.
