Is Viton resistant to acid?

Is Viton resistant to acid?

Viton is characterized by its: Resistance to degradation by a greater variety of fluids and chemicals than any nonfluorinated elastomer. Excellent resistance to oils, fuels, lubricants, and most mineral acids.

Are Viton seals acid resistant?

Type F Viton® o-rings, seals, and gaskets are highly resistant to oxygenated automotive fuels, concentrated aqueous inorganic acids, water, and steam. Fluorine content of these materials is roughly 70%.

Is Viton flammable?

Viton™ Curative Nos. 1 (VC-1) and 3 (VC-3) may cause irritation of eyes and skin and may also form flammable dust-air mixtures. They should be kept away from heat, sparks, and flame and only used where equipment is grounded.

Does Sulphuric acid react with plastic?

It depends on the plastic. Because it is an ester, PET (polyethylene terephthalate) is easily hydrolysed by sulphuric acid. The hydrocarbon plastics such as polyethylene and polypropylene are unreactive to most acids and cold sulfuric is OK but hot acid is not recommended.

Is Viton hazardous?

Using recommended handling procedures, raw un- precompounded Viton™ fluoroelastomers present no significant health hazards.

Is Viton toxic?

Significant skin permeation and systemic toxicity after contact appears unlikely. There are no reports of human sensitization. Inhalation of fumes from burning polymer may cause temporary lung irritation effects with cough, discomfort, difficulty breathing, or shortness of breath.

What is the chemical compatibility of Viton®?

Viton® Chemical Compatibility Chart: Check the chemical compatibility of Viton® with various chemicals, solvents, alcohols and other products. A trademark of DuPont, Viton fluoroelastomer in general has a high temperature tolerance and chemical resistance rating.

What is the FKM rating used for?

It is to be used only as a guide in selecting equipment for appropriate chemical compatibility. Before permanent installation, test the equipment with the chemicals and under the specific conditions of your application. Fluoroelastomer (FKM) is rated for use in individual chemicals at room temperature.

Can Viton rubber be used with ketones?

It is a synthetic rubber that resists many hydrocarbons, biodiesel, and petro chemicals, but is NOT compatible with ketones. Do not use Viton with acetone, esters, amines, organic acids, acetic acid, MEK, ethyl acetate, highly polar chemicals, etc.

What is flouroelastomer (FKM)?

Fluoroelastomer (FKM) resists over 300 different chemicals. Our Flouroelastomer (FKM) database is derived from various polymer suppliers, rubber manufacturers, and reputable industry sources. It is to be used only as a guide in selecting equipment for appropriate chemical compatibility.

What material is compatible with sulfuric acid?

For 90% to 100% sulfuric acid, a good choice would be 316L stainless steel. Since it is a molybdenum bearing grade, it has improved resistance to velocity enhanced corrosion or impingement in valves.

What plastic is resistant to sulfuric acid?

1. PTFE (or Teflon™) – PTFE, also commonly known as Teflon™, is one of the most acid resistant materials available and is commonly used in chemical and pharmaceutical lab applications.

Is Viton compatible with Skydrol?

What Seals are compatible with Skydrol? Elastomers are the big issue. Don’t get it wrong. Nitrile, Buna-N, silicone, fluorosilicone and Viton fluorocarbon are totally unsuitable.

What metals are compatible with ammonia?

Air-cooling evaporators used in ammonia systems have traditionally been made using galvanized (zinc-coated) carbon steel. There are other metals that are compatible with ammonia, including stainless steel and aluminum.

Is stainless steel compatible with sulfuric acid?

2. The high silicon austenitic stainless steels have good corrosion resistance in hot concentrated sulphuric acid and are better than 310 in weaker acid. The silicon gives these alloys good resistance to sulphuric acid at high flow velocities. These alloys are less resistant in oleum compared with alloy 310.

Is Viton gasoline proof?

This material has an excellent tolerance for high temperatures, resistance to oils, fuels and hydraulic fluids as well as aromatics and solvents. As well as resisting oils, petrol and hydrocarbons, Viton™ is resistant to mineral acids, halogenated hydrocarbons and more.

Which plastic does not react with acid?

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.
