The following is a run-down of the basic characteristics of LHSS's general purpose, elastomers:

Silicone, VMQ is generally resistant to oxidising chemicals, ozone, concentrated hydrogen; by attacked by many solvents and concentrated acids.


Fluorosilicone, FVMQ, is similar to silicone, but also resistant to gasoline, aromatic solvents and chlorinated solvents. It is attacked by ketones and selected chemicals such as hydrazine.


Fluorocarbon, FKM, is resistant to all aliphatic, aromatic, and halogenated hydrocarbons, acids, vegetable and animal oils; but is attacked by ketones, low molecular weight esters and nltro containing compounds.


Neoprene, CR, is generally resistant to mild chemicals and aliphatic hydrocarbons, ozone, selected oils and solvents; but is attacked by strong oxidizing acids, esters, ketones, and chlorinated aromatic hydrocarbons.


Nitrile, NBR, is generally resistant to hydrocarbons, fats, oils, greases, hydraulic fluids, and a variety of other chemicals, but is attacked by ketones, esters, aldehydes, aromatic hydrocarbons and nitrocarbons.


Ethylene Propylene, EPDM, is generally resistant to animal and vegetable oils, strong oxidising chemicals, and ozone, but is attacked by mineral oils, solvents and aromatic hydrocarbons.
