Patent number: 11339899Abstract: A multilayer tubular structure (MLT) for transport of alcohol-containing petrol. The MLT from the outside inwards has at least one barrier layer and at least one inner layer located below the barrier layer. The inner layer, or all the layers contain on average at most 1.5% of plasticizer relative to the total weight of the composition of each layer or to the total weight of all the compositions of the layers. The inner layer is predominantly made of at least one polyamide having more than 75% aliphatic units. The aliphatic polyamide has a mean number of carbon atoms per nitrogen atom selected from the following: A: from 4 to 8.5; B: from 7 to 10; C: from 9 to 18; with the proviso that when the inner layer comprises at least three polyamides, at least one of the polyamides A, B and C is excluded.Type: GrantFiled: January 12, 2017Date of Patent: May 24, 2022Assignee: Arkema FranceInventors: Thibaut Montanari, Christelle Recoquille, Bertrand Verbauwhede, Nicolas Dufaure, Florent Dechamps

Patent number: 10914408Abstract: Provided is a method of determining whether a multilayer tubular structure (MLT) satisfies an extractables test by filling the multilayer tubular structure MLT with an alcohol-containing petrol of FAM B type to obtain a filled MLT and measuring the amount of extractable material. The MLT satisfies the extractables test when the residue of the filtrate is less than or equal to 6 g/m2 of the inner surface area of the MLT.Type: GrantFiled: December 13, 2019Date of Patent: February 9, 2021Assignee: Arkema FranceInventors: Thibaut Montanari, Christelle Recoquille, Bertrand Verbauwhede, Nicolas Dufaure, Florent Dechamps
