MULTILAYER TUBE BASED ON POLYAMIDE AND FLUORINE POLYMER FOR THE TRANSFER OF FLUIDS |
| abstract |
The present invention relates to a multilayer tube comprising in its radial direction from the outside to the inside: an outer layer (1) of polyamide, an inner layer (2) of a composition comprising, the total being 100%: 5 to 30% by weight of a mixture (A) comprising: a polyethylene bearing epoxy functions, an impact modifier selected from elastomers and very low density polyethylenes, said impact modifier being wholly or partly functionalized, 95 to 70% by weight weight of a mixture (B) comprising: a fluorinated polymer (B1), a functionalized fluoropolymer (B2), the proportion of (B2) is between 1 and 60% by weight of (A) + (B), the layers being successive and adhering to each other in their respective contact zone. The inner layer is the layer in contact with the transported fluid. According to an advantageous form, there is disposed between the layer (2) and the layer (3) a functionalized polyolefin layer having functions capable of reacting with the functions of the fluorinated polymer (B2 The tube of the present invention is very poorly permeable to the cooling liquid and its additives (boric acid and its salts). These tubes also have good resistance to fuels and engine lubricating oils. This tube has very good mechanical properties at low or high temperature. These tubes can be smooth or corrugated. The invention also relates to the use of these tubes for transporting coolant. |
