Abstract

The invention relates to a thermoplastic composition for a monolayer tube (T1, T2), and particularly to an air-conditioning circuit for a motor vehicle comprising tubes transporting a refrigerating fluid. The composition comprises in weight fractions: - more than 20% and up to 40% of an aliphatic polyamide comprising a PA 6.10 and/or PA 6.12, - from 45% to less than 60% of a polyphthalamide having a Tg higher than 120°C and selected from PA 6.I/6.T, PA 9.T, PA 10.T, PA 10.T/X, and - from 10% to 20% of a compatibilizing system comprising a reaction product between (a) a polymer of olefin comprising an unsaturated epoxide and (b) a polymer of olefin comprising an unsaturated carboxylic acid, with weight ratio (a):(b) greater than 1.
