PLASTICS IN FUEL APPLICATIONS Automakers have traditionally turned to a variety of polymers when building auto fuel-system components: Polyamides, including nylon 6/6, high-temperature nylon (HTN), and nylon 12, top the material choice list. Nylon 6/6 is economical and has good strength and toughness.

What plastic can withstand acid?

Polypropylene – Polypropylene is a thermoplastic polymer that's rugged and resistant to many acids. It can also function as both a plastic and a fiber, and because of that has one of the largest varieties of applications of all plastics.

What plastic does not react with acid?

Teflon (PTFE)

As a synthetic fluoropolymer, PTFE is very non-reactive and has proven to be an exceptionally useful material. Its unique chemical inertness makes it acid-resistant and it is often used in containers and pipework for reactive and corrosive chemicals.

Is PVC gasoline resistant?

Can PVC and other plastic hoses be used for fuels and gas? In short, the answer is no, they cannot. ... Due to the nature of PVC and other plastics as well, they are not well suited to use for fuel gas or kerosene. PVC and other plastics deform easily in high temperature environments, and may leak or rupture.

Is polyethylene safe for gasoline?

Chemicals such as gasoline, kerosene, alcohol, methanol, and isopropyl alcohol can potentially permeate the polyethylene material and leak through the poly tank. Solvents can also degrade or soften polyethylene, affecting performance and durability of the poly tank.

Does Vaseline dissolve plastic?

Petroleum jelly is very sticky and hard to remove from non-biological surfaces with the usual and customary cleaning agents typically found in the home. It may be dissolved with paint thinner or other petroleum solvents such as acetone, which dissolves most plastics.

What plastic is safe for hydrochloric acid?

Storing Hydrochloric Acid

Metal containers are not suitable storage containers for hydrochloric acid due to its corrosive nature. Plastic containers, such as those made of PVC, can typically be used to store hydrochloric acid.

Why can't acid eat through plastic?

It stored in the plastic containers due to its high reactivity. Because Plastic contains the sum content like Fluorocarbon, chloro-sulfonated polyethylenene, natural rubber which are considered as a resistant for the Hydrofluoric acid. That's the main reason because of which it doesn't dissolved the plastic.

Is acetone compatible with plastic?

Methylene chloride and acetone will help remove oils, however prolonged exposure to such organic solvents can cause swelling of certain plastics. In general do not use solvents with polycarbonate, PVC, acrylic or polystyrene. For more detailed information on cleaning procedures contact our technical dept.

What happens when acid reacts with plastic?

A polyethylene or polypropylene plastic is composed of long lengths of C-C chains, which have no bonds susceptible to the acid. The C-C chain is inert to both dilute and conc. acid. Hydrochloric, nitric, and sulfuric acids are now routinely supplied in plastic rather than glass bottles.

Can gasoline dissolve plastic?

Gasoline can dissolve certain kinds of plastic, leading to further spillage. If the gas is exposed to a spark, it could trigger a life-threatening fire. Officials recommend using a Transportation Department-approved container with a proper lid for handling flammable liquids.

Can you put gasoline in a plastic container?

"Do not fill plastic bags with gasoline," the agency tweeted Wednesday. ... If you know someone who is thinking about bringing a container not meant for fuel to get gas, please let them know it's dangerous." The commission added that people should never pour gasoline over or near an open flame.

What is the best material for fuel lines?

The best solution is a material called PTFE. That stands for polytetrafluoroethylene—a plastic material that is best known as Teflon in one specific variation. This material is impervious to the degenerative effects of fuel that also creates a vapor barrier so fuel vapors cannot leak past.
