CLAIMS

1. Conduit for a cooling system, a heating system, an air intake system, an exhaust system, a pressure system or a fuel system, consisting of, or comprising a part or a layer made of a thermoplastic polymer composition comprising a semi-crystalline semi-aromatic polyamide having a glass transition temperature (Tg) of at least 1 159C.

2. Conduit according to claim 1 , wherein the semi-crystalline semi-aromatic polyamide (A) has a glass transition temperature of at least 120°C, and/or the a melting temperature (Tm-A) of at least 270 °C, and/or a density, of at least

1.20.

3. Conduit according to claim 1 or 2, wherein the semi-crystalline semi-aromatic polyamide (A) consists of repeat units derived from:

(a) 25-45 mole % terephthalic acid, (b) 5-25 mole % of an aromatic dicarboxylic acid different from terephthalic acid, and/or an aliphatic dicarboxylic acid

(c) 5-30 mole% of an diamine chosen from the group consisting of ethylene diamine, trimethylene diamine, tetramethylene diamine and pentamethylene diamine (d) 20-45 mole% of a diamine comprising at least 6 C-atoms, and optionally

(e) 0 - 10 mole % of one or more aminocarboxylic acids and/or lactams, and

(f) 0 - 3 mole % of one or more compounds being mono-functional or tri- functional in amino and /or carboxylic acid groups; wherein the mole % of each of a-f is relative to the total of a-f, and the total of a-f is 100%.

4. Conduit according to any of claims 1 -3, wherein the thermoplastic polymer composition comprises at least one other polymer, and/or a reinforcing agent, and/or a filler, and/or at least one other additive.

5. Conduit according to any of claims 1 -4, wherein thermoplastic polymer composition consists of

(A) 40 - 95 wt.% of the semi-crystalline semi-aromatic polyamide,

(B) 0 - 40 wt.% of a at least one other polymer

(C) 5 - 40 wt.% of glass fillers and/or fibres

(D) 0.01 - 10 wt.% of the at least one additive wherein the weight percentages (wt.%) are relative to the total weight of the polymer composition. 6. Plastic container for a cooling system, a heating system, an air intake system, an exhaust system, a pressure system or a fuel system, comprising a layer made of a thermoplastic polymer composition comprising a semi-crystalline semi-aromatic polyamide having a glass transition temperature (Tg) of at least 1 159C and a layer made from the thermoplastic polymer composition and at least one layer consisting of a polymer composition different from the thermoplastic polymer composition. 7. Plastic container according to claim 6, wherein the semi-crystalline semi- aromatic polyamide is a semi-crystalline semi-aromatic polyamide as described in any of claims 2-5.

8. Component for a heating device or fuel system, wherein the component is a door handle, a door trim, a housing, a wall panel or a part thereof, a pump element, made of a thermoplastic polymer composition comprising a semi- crystalline semi-aromatic polyamide having a glass transition of at least 1 15<O.

9. Component according to claim 8, wherein the semi-crystalline semi-aromatic polyamide is a semi-crystalline semi-aromatic polyamide as described in any of claims 2-5.

10. Use of a conduit according to claim 1 -5, a container according to claim 6 or 7, or a component according to claim 8 or 9, in an cooling system, a heating system, an air intake system, an exhaust system, a pressure system or fuel system. 1 1. Use according to claim 10, wherein the cooling system, the heating system, the air intake system, the exhaust system, the pressure system or the fuel system is part of an automotive engine.

12. Use according to claim 10 or 1 1 , wherein the container or conduit is in direct contact with hot air, water, cooling liquid, oil, or fuel 13. A heating system, a cooling system, an air intake system, an exhaust system, a pressure system or a fuel system comprising a conduit according to claim 1 - 5, or a container according to claim 6 or 7, and/or a component according to claim 8 or 9.
