Low resistance to hydrocarbon fluids like gasoline or paraffin fluids or steam above to 50 psi.

Broad temperature range.
Good ozone resistance
Resistant to compression set.

SILICONE

Poor resistance to ozone and weather aging.

Commonly referred to as Buna-N or NBR and is copolymer of Butadiene and Acryonitrile.
Good resistance to petroleum oils, water, silicone oil, greases, glycol base fluids.
Good abrasion resistance, cold flow, tear resistance.

NITRILE

Poor cold temperature limit, dry running ability, water resistance.
Lower mechanical strength.

Polymerised acrylic acidesters or PA and ACM.
Good resistance to mineral oil, hypoid gear oil E.P. additive, greases, aging and flex cracking.

POLYACRYLATE

Fair resistance to water, dry running.
Low temperature resistance is fair.

Good temperature resistance.
Commonly chosen as high temperature replacement for Nitrile or Polyacrylate.
