The present invention relates to mixtures of polyamide (A) and polyolefin (B) containing nanofillers in which the polyamide forms the matrix. These mixtures can also be called "mixtures of polyamide (A), polyolefin (B) and nanofillers in which the polyamide forms the matrix".n n n The invention also relates to compositions with barrier properties which are mixtures of polyamide (A) and polyolefin (B) containing nanofillers in which the polyamide forms the matrix.n n n The invention also relates to structures with barrier properties comprising at least one layer of these mixtures and optionally at least one layer of another material.n n n The invention also relates to the use of these structures to obtain a barrier effect.n n n These structures are a barrier to many fluids and in particular to oxygen, styrene, fumigation fluids, pentane and air conditioning fluids.n n n These structures can be in the form of bottles, tanks, containers, pipes and containers of all kinds. They can also be transformed into films with which we make packaging. These films are also useful in food packaging, in SMC technology, in fumigation and in the packaging of expandable polystyrene. These pipes are useful in air conditioning systems.n n n The invention also relates to the use of these objects. |
