Definitions
- shrinkage should remain as low as possible at the end of the manufacturing process (just like with conventional connectors made from PA 12 for instance).
- the at least one first polyamide A is selected from PA 6, PA 4.6, PA 6.6, PA 6/6.6, PA 6/6.T, PA 6.6/6.T, PA 6.6/6.1, PA 6.1/6.T, PA 6.6/6.1/6.T, PA 6.10 and mixtures thereof, and preferably is PA 6.
- the composition comprises from 1 to 70 wt. %, preferably from 2 to 60 wt. % and more preferably from 3 to 50 wt. %, in particular from 3 to 35% wt. % of the at least one first polyamide A.
- the mass-weighted mean of the heats of fusion of these polyamides A, B and C in the said composition is greater than 25 J/g (DSC, ISO 11357-3 (2013)).
- the second polyamide B is selected from PA 6.10, PA 6.12 and a mixture thereof; and/or the third polyamide C is selected from PA 6.14, PA 10.10, PA 11, PA 12, PA 10.12, PA 6.18, PA 12.T, PA 12/10.T, PA 10.10/10.T, PA B.12, PA B.10/10.10, PA IPD.10, PA B.I/12 and mixtures thereof, preferably from PA 10.10, PA 10.12 and PA 12 and a mixture thereof; and more preferably is PA 12.
- the composition consists of one first polyamide A, one second polyamide B, one third polyamide C and optionally non-polyamide additives; and preferably, the first polyamide A is PA 6, the second polyamide B is PA 6.10 and the third polyamide C is PA 10.10, PA 10.12 or PA 12.
- the composition consists of one first polyamide A, one second polyamide B, one third polyamide C and optionally non-polyamide additives; and preferably, the first polyamide A is PA 6, the second polyamide B is PA 6.12, and the third polyamide C is PA 10.10, PA 10.12 or PA 12.
- the tube connector part is configured for being welded to one or more tubes, preferably by spin welding, said tubes being preferably polyamide tubes.
- the tube connector part is part of a circuit for conveying liquids or gases in motor vehicles.
- An embodiment of the disclosure also relates to a process of making the above-described tube connector part, comprising melting and shaping the polyamide composition.
- the average number of carbon atoms per nitrogen atom corresponds to the molar pro rata of the various amide units.
- PEBA 12 which is a block copolymer of amide units of the PA 12 type and of ether units
- the mean number of carbon atoms per nitrogen atom is 12, like for PA 12; for PEBA 6.12, it is 9, like for PA 6.12.
- the copolyamides used in an embodiment of the disclosure contain only amide units.
- a copper-based thermal stabilizer may be used, in particular a copper salt or a copper salt derivative, such as copper iodide, copper bromide, copper halides, derivatives of mixtures thereof.
- Copper salts I are preferred. Examples are copper iodide, copper bromide, copper chloride, copper fluoride, copper thiocyanate, copper nitrate, copper acetate, copper naphthenate, copper caprate, copper laurate, copper stearate, copper acetylacetonate, copper oxide.
- thermal stabilizers are sterically-hindered phenolic antioxidants.
- fillers mention may be made of silica, graphite, expanded graphite, carbon black, glass beads, kaolin, magnesia, slag, talc, carbon nanocharges (such as carbon nanotubes), metallic oxides (titanium oxide), metals, and more preferably fibers (aramides, glass fibers, carbon fibers).
- the composition may contain up to 20 wt. % of such additional polymers.
- Welding may notably be achieved by hot gas welding, speed tip welding, extrusion welding, contact welding, overmolding, hot plate welding, high frequency welding, injection welding, ultrasound welding, friction welding, spin welding and solvent welding.
- the connectors or connector parts may in particular be welded to articles or layers made of polyamide compositions, such as polyamide compositions based on PA 6, or on
- the connectors or connector parts of an embodiment of the disclosure may thus be incorporated into fluidic circuits such as circuits for storing and conveying liquid or gases, in particular fuel or refrigerant, and more particularly in a motor vehicle.
