Title:
USE OF SEMI-AROMATIC COPOLYAMIDE FOR TRANSPORTING REFRIGERANT FLUID
Document Type and Number:
Japanese Patent JP2018168374
Kind Code:
A
Abstract:
To provide vapor compression circuit elements that display an effective compromise between their properties of imperviousness to the heat transfer fluid, to water, and to oxygen, their chemical resistance to the heat transfer fluid, to water, and to oxygen, their mechanical strength, their flexibility, and their heat resistance.SOLUTION: There are provided vapor compression circuit elements comprising a layer consisting of a composition comprising a copolyamide of formula X/10.T/Y, wherein X represents either the residues of an aliphatic amino acid comprising between 8 and 18 carbon atoms, or a lactam, or the motif X1.X2 representing the residues resulting from the condensation of an aliphatic diamine comprising between 6 and 18 carbon atoms and a (cyclo)aliphatic diacid comprising between 6 and 18 carbon atoms; 10.T represents the residues resulting from the condensation of a decanediamine and terephthalic acid; and Y represents the residues resulting from the condensation of an aliphatic diamine comprising between 9 and 14 carbon atoms and an aromatic diacid, Y being different from the motif 10.T.SELECTED DRAWING: None
