<p>23443-493 Thermoplastic laminates A thermoplastic laminate comprising at least one layer of a moulding composition based on a polyamide and at least one layer made of a moulding composition based on a mixture of 99 to 60% by weight of a partly crystalline thermoplastic polyester and 1 to 40% by weight of a compound containing at least two isocyanate groups. The isocyanate groups constitute 0.03 to 3% by weight of the second moulding composition. The laminates according to the invention are solvent-resistant and have a strong cohesive bond at the phase interfaces. The bond between polyester and polyamide is thermally stable, is not affected by shear stress and has good mechanical properties. The laminates according to the invention are used in structural components, particularly in electrical, mechanical and automobile engineering, but also as food packaging films. . ,</p> |
