Rubber Characteristics

Rubber Characteristics Chart

Type

Abbrev.

Positive Characteristics

Nitrile

NBR

Superior resistance to petroleum based hydraulic fluids, and very good resistance to gasoline and oil.

Natural Rubber

NR

Offers good tear and abrasion properties, Very good tensile strength and resilience.

Neoprene

CR

Generic, versatile rubber with moderate oil resistance and good flame resistance characteristics, and has some ozone resistance.

EPDM

EPDM

This rubber has good resistance to heat, ozone and sunlight.  It retains good flexibility at low temperatures.

SBR

Buna-S

Good impact strength while flexible at low temperatures.  This rubber is generally least expensive, making it a great all purpose rubber.

Silicone

SI

Great in high heat applications or in cold. Will work in applications where weather, ozone and sunlight are factors.

Fluorocarbon
Viton

FKM

Good fit for high temperature applications, is resistant to fuel and oils, and hydrocarbon fluids.
