The development of synthetic rubbers stemmed from the need to create materials with greater resistance to fuels and oils. Aggressive chemicals, hydraulic oils, food substances and refrigerants all have to be carefully formulated and tested to ensure safe and predictable service lives.
Rubber is used for seals and gaskets in almost any chemical environment and for mechanical components in machinery of all kinds. It is also suitable for parts which must be reasonably resistant to normal contaminants, such a printed circuit board components which will be solvent cleaned.
For moderate resistance to oils and fuels :
Good resistance to oils and fuels :
Extreme resistance to many chemicals :
Examples of Components
Nitrile rubber bearing cup to insulate the commutator bearing of electric motors. This material must withstand high tempreture ozone and grease, as well as copper and carbon dust.
