USE OF THERMOPLASTIC COMPOSITIONS FOR THE THERMAL PROTECTION OF SUBSTRATES |
摘要 |
The invention relates to the use of a thermoplastic composition in a nanostructured form, said composition essentially comprising a grafted copolymer with polyamide blocks, consisting of a polyolefin trunk selected from the maleic ethylene anhydride and maleic alkyl anhydride ethylene (meth)acrylate copolymers, and at least one polyamide graft, for the thermal protection of a substrate, at a temperature higher than 150°C. The invention is characterised in that at least one layer of said composition is deposited on the substrate. According to a preferred embodiment, the coating layer is deposited by coextrusion on the substrate layer, especially for obtaining tubes or pipes used in petrol lines. |
