What is Viton not compatible with?
Do not use Viton with acetone, esters, amines, organic acids, acetic acid, MEK, ethyl acetate, highly polar chemicals, etc. Viton is generally serviceable in dynamic applications to temperatures of -18 to -23 °C.
What is Chemraz 505?
Greene Tweed’s Chemraz® 505, a perfluoroelastomer, provides a broad range of chemical resistance, and is available for use as o-rings, gaskets, and many other custom shapes.
Is Viton compatible with ammonia?
The Viton® A is a fluoroelastomer dipolymer comprised of vinylidene fluoride and hexafluropropylene. Provides good chemcial resistance to petroleum products and solvents. Avoid polar solvents, amines, anhydrous ammonia, hydrazine and hot acids.
Will sulfuric acid dissolve rubber?
Hydrochloric acid, hydrofluoric acid and sulfuric acid attack and degrade Buna-N rubber.
Is silicone resistant to sulfuric acid?
Chemical resistance of silicone rubber Silicones are in general, chemically inert and are attacked by only a few common materials. Among them are concentrated sulphuric acid, hydrofluoric acid and under long term exposure, high pressure steam.
What is the difference between Kalrez and Chemraz?
The effective temperature range for Kalrez is +5ºF to + 600ºF, for Chemraz –20ºF to +450ºF. A white Chemraz compound is available and features less impurities and less electrical conductivity.
Is EPDM suitable for acid?
EPDM has good resistance to many chemical products like detergents, caustic potash solutions, sodium hydroxide solutions, and many other diluted acids and chemicals. It is not resistant to most hydrocarbons, such as oils, kerosene, gasoline, and many solvents.
Is Viton suitable for H2S?
Viton Extreme ETP-600S which is an APA (Advanced Polymer Architecture) Viton is suitable for making and application in very sour gas (23% H2S, 11% CO2 and the rest CH4 and low molecular weight hydrocarbons, amine corrosion inhibitors, methanol and water) at 32°C and 1200 psi (specially for o-ring applications).
What material is resistant to sulfuric acid?
High Silicon—The high-silicon irons, such as Duriron and Corrosiron exhibit excellent resistance to all concentrations of sulfuric acid up to and including boiling temperatures. They are available in cast form only.
What plastic can withstand 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.
Does acid react with silicone?
With regards to the effects of solvents and industrial chemicals on silicone rubber, the following data has been complied: Silicones are chemically inert and are attacked by very few common materials. Among them are concentrated sulphuric acid, hydrofluoric acid and, after long term exposure, high pressure steam.
Is Kalrez a PTFE?
In addition, Kalrez® is a thermoset perfluoroelastomer part and offers excellent elastic properties and resistance to mechanical damage, unlike PTFE which is a thermoplastic and appears to lack the necessary resilience to withstand mechanical shock in a process application such as this.
Is FKM and Viton the same?
These rubber compounds give exceptional heat resistance with compatibility across many fluids or chemical exposures. The most commonly known name for these compounds is “Viton,”™ which has become the generic name for all FKM polymers and rubber compounds.
Is EPDM good for sulfuric acid?
EPDM has good abrasion and tear resistance to a variety of acids and bases. It is susceptible to attack by oils and is not recommended for applications involving petroleum oils, strong acids or strong bases.
