Elastomers and Performance Characteristics

 

Butyl+Excellent resistance to acids and alkalis.
IIR (isobutylene-isoprene)Excellent weathering properties and heat resistance.

Excellent electrical resistance. Low permeability to air.

-Poor resistance to fuels, solvents, oils and hydrocarbons.
Cold weather properties are fair.

CPE
+
Excellent oxidation resistance.
(Chlorinated Polyethylene)Good oil resistance, heat resistance, ozone resistance and weather resistance.

Fair resistance to ketones and ethers.

-Poor cold weather properties.

EPDM+Excellent resistance to ozone, sunlight and oxygen.

(ethylene-propylene diene)Excellent resistance to acids, alkalis and ketones.

Excellent heat resistance and aging.

-Poor resistance to fuels and oils.

Fluoroelastomer+Excellent resistance to heat and oil combinations: hot greases found in engines and compressors.
(VITON fluroelastomer, a registered trademark of DuPont Dow Elastomers)Excellent resistance to a wide range of concentrated acids.

-High cost of fluoroelastomer may limit usage to extreme applications. Resilience is low and tear strength is limited unless certain compounding steps are taken to improve it. Impact resistance is fair.

SBR
(Styrene butadiene)
+Good abrasion resistance and excellent impact and cut-and-gouge resistance. Can be compounded for use as skirtboard rubber, lining rubber, conveyor belt covers, tires and other extremely demanding applications. Used as gasket material and as an economical general purpose sheet.


-Not suited for use with oils, fuels, solvents, or hydraulic fluids.

Silicone+Excellent properties for both hot and cold temperature extremes; excellent weathering properties; resists ozone and oxygen attack. Long service life can be expected at 200F to 400F (93C to 204C).


-Poor resistance to oils, fuels, and hydrocarbons. Fair performance when exposed to acids, alkalis and solvents. Physical properties (tensile, abrasion, tear and cut growth) are fair.

Natural Rubber
NR (Gum)
+Good gasket material due to excellent physical properties such as resilience, tear strength and wear resistance. Natural rubber is used effectively as sand and shot blast curtain material because of its high abrasion resistance and resilience.


-Deteriorates when exposed to oils, fuels, solvents, and hydraulic fluids. Poor resistance to sunlight, ozone and oxygen.

Neoprene
CR (chloroprene)
+Good oil- and petroleum-based solvent resistance. Good weather and ozone resistance. Neoprene may be blended with SBR rubberto achieve an economically priced sheet for moderately oil resistant applications.


-Poor resistance to degreaser solvents. Content levels of neoprene can vary widely. Application problems may occur when using blended or commercial grades of neoprene sheet of unknown quality levels in contact with oil, solvents and fuels.

Where good oil or fuel resistance is required, the fabricator and user need to specify one of the following:
• A known manufacturer's product
• An ASTM call-out
• A military specification
• An ASTM-specified oil resistance level based on an ASTM test (e.g. oil swell)

Nitrile+Excellent resistance to oils, solvents and fuels.
(butadiene-acrylonitrile)

Resistant to a broader range of aromatic hydrocarbons than neo- prene. Nitrile may be blended with SBR rubber to achieve an economically priced sheet for moderately oil resistant applications.


-Application problems may occur when using nitrile of unknown quality levels in extreme oil resistance applications or in contact with fuels and solvents.
Content levels of nitrile can vary widely.
Where oil or fuel resistance is required, the fabricator and user need to specify one of the following:

• A known manufacturer's product
• An ASTM call-out
• A military specification
• An ASTM-specified oil resistance level based on an
ASTM test (e.g. oil swell)
