Systems and methods are disclosed that include providing a multilayer tubing construction with an inner layer, an intermediate layer, and an outer or third layer formed from a material comprising a non-phthalate plasticizer, such as TOTM, DOA, DOTP, or combinations thereof. The multilayer tubing may be suitable for carrying a fuel, or other flammable substances therethrough, and resists delamination between layers when exposed to high humidity climates.

Multilayer tubing for chemical transfer applications

A multilayer flexible tube includes an inner layer including a melt processable fluoropolymer, wherein the melt processable fluoropolymer includes a terpolymer including a tetrafluoroethylene, a hexafluoropropylene, and a vinylidene fluoride (THV); a tie layer including a polymeric blend of a terpolymer including a tetrafluoroethylene, a hexafluoropropylene, and a vinylidene fluoride (THV) with a poly vinylidene fluoride (PVDF), a polyamide, a polyetheramide block copolymer, or combination thereof; and an outer layer including a melt processable polymer having a shore hardness less than a shore hardness of the inner layer.
