Systems and methods are disclosed that include providing a tubing construction with at least one layer formed from a thermoplastic vulcanizate (TPV). The tubing construction is suitable for use in pump applications subjected to cyclic loading and unloading. The tubing construction maintains a flowrate stability of +/−10% for an extended period of time to provide consistent fluid dispensing and/or dosing for an extended life of the tubing construction and/or the fluid pump.

Long life pump tubing

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 tube includes: an inner layer including a polymer, wherein the polymer includes a fluoropolymer, a polyolefin, a blend thereof, or combination thereof; and an outer layer adjacent to the inner layer, wherein the outer layer includes a polymer including a fluoropolymer, a polyolefin, a blend thereof, or combination thereof; wherein the inner layer, the outer layer, or combination thereof includes at least one blocking agent, wherein the at least one blocking agent reduces the percent transmission by at least 99% at wavelengths between 240 nm to 450 nm.

Tube and method for making same

A composite tube includes a first layer including a cross-linked polyolefin elastomer, wherein the first layer is configured for fluid contact; and a second layer adjacent to the first layer, the second layer including an elastomer.

Composite tube and method of making

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.

Multilayer flexible tube and methods for making same

The present disclosure relates to multi-layered tubings that are fuel resistant and resistant to delamination. In one aspect, the disclosure provides a length of tubing having an annular cross-section including an annular fluoropolymer layer formed from at least 75 wt % fluoropolymer (e.g., at least 75 wt % of a PVDF polymer), the fluoropolymer layer having an outer surface and an inner surface; and disposed about the fluoropolymer layer, an annular thermoplastic layer formed from at least 75 wt % thermoplastic (e.g., thermoplastic polyurethane, thermoplastic polyamide and/or thermoplastic polyester), the thermoplastic polyurethane layer having an inner surface in contact with the outer surface of the fluoropolymer layer and an outer surface, wherein the fluoropolymer layer is covalently bound to the thermoplastic polyurethane layer, for example, by electron beam treatment.

Fuel tubings and methods for making and using same

A multilayer flexible tube includes an inner layer including a melt processable fluoropolymer, wherein the fluoropolymer includes a copolymer of a poly vinylidene fluoride (PVDF) and a hexafluoropropylene (HFP); and an outer layer including a melt processable polymer having a shore hardness less than a shore hardness of the inner layer, wherein the multilayer flexible tube has a maximum storage modulus of at least 300 MegaPascal (MPa) at a temperature of about &#x2212;10&#xb0; C.
