It is supposed to be a plastic pipe with improved resistance u. a. against methanol-containing fuels and improved mechanical properties.n n n I. mindestens aus einer Außenschicht, II. mindestens aus einer Innenschicht auf Basis einer Formmasse aus Polyvinylidenfluorid III. aus einer zu der Innenschicht II. nach außen benachbarten Schicht auf Basis einer Formmasse aus einer Mischung ausn a. Polyamid b. Poly(alkyl)acrylsäureester, wobei die Schichten miteinander kraftschlüssig verbunden sind.This is achieved through a multi-layer plastic tube consisting of I. at least from an outer layer, II. At least from an inner layer based on a molding compound made of polyvinylidene fluoride III. from a layer adjacent to the inner layer II. on the outside based on a molding compound made from a mixture of a. polyamide b. Poly (alkyl) acrylic acid esters, the layers being non-positively connected to one another.n n n With the help of the invention it is possible to obtain plastic pipes with the desired improved properties. |
