Abstract: The present invention relates to a novel polyamide alloy composition that is useful for forming objects that may be used for the storage and transport of fluids. The polyamide alloy is a blend of at least one polyamide and at least one modified polyolefin having both medium to hard and soft domains. The polyamide forms the continuous phase of the alloy. The alloy may also contain, and preferably does contain, a thermal and light stabilization compound, at least one unmodified polyolefin, and at least one plasticizer. The polyamide alloy composition is useful in forming tanks, hoses and tubes used in the transport of liquid or gaseous fluids, including fluids under pressure.

Abstract: The present invention concerns multi-layer structures comprising at least a layer of a thermoplastic compound containing nanofillers and at least a layer of rubber. These structures can be converted to bottles, reservoirs, containers, pipes, hoses and vessels of all sorts. The structures of the invention are of interest for the cryogenic fluids used in air conditioning, such as for example HFAs and HFCs.

Abstract: The present invention relates to a low oligomer conductive polyamide composition, and articles of manufacture useful in the art of the transport of fluids such as solvents, polar fluids and fuels for applications such as fuel hoses or tubing for internal combustion engines. The material in the hose which is in contact with the fuel must be resistant to the extraction of materials from the hose which precipitate into the fuel or have the potential to clog fuel filters, fuel injectors and the like which have extremely small orifices and, thus, low tolerance for particulates in the fuel. As used herein, the term “low precipitate polyamide” means that the polyamide has been washed or extracted to reduce the level of components such as oligomers (low molecular weight polyamide), solids or semi-solids which would otherwise be released by the polyamide after exposure to the transported fluid and/or precipitate into the fluid.
