Elastomers Properties
Operating-temperature ranges for rubbers and elastomers
Typical operating temperature-ranges for elastomers:
| ID (DIN ISO 1629) | Name | Characterized by | Typical Applicatons | Typical Operationg Temperature Range (oC) |
|---|---|---|---|---|
| ACM | polyacrylic rubber | good hot-air resistance good ozon and weather resistance good resistance to lubricating oils with additives low elasticity medium strength |
oil seals higher temperature seals |
-20 - 150 |
| AEM | ethylene acrylate rubber | good mechanical properties temperature resistant good compression ratio | oil seals higher temperature seals |
-40 - 160 |
| CR | chloroprene rubber | good weather, ozone, aging and chemical resistance high flame retardance good mechanical properties abrasion resistance flexible in low temperatures |
refrigerant sealings outdoor seals adhesives or glues |
-35 - 90 |
| ECO | epichlorohydrin rubber | resistant to engine oil and fuels very low gas permeability weather and ozone resistant low compression ratio |
in engine bearings vibration dampers fuel lines |
-40 - 120 |
| EPDM | ethylene propylene dietene rubber | high elasticity weather resistant good heat, ozzone and aging resistance good low-temperature performance |
parts in contact with brake fluids, cooling water, refrigerants | -40 - 150 |
| FKM | fluorine rubber | good resistance to oils, fuels and aggressive media very good aging, ozone and weather resistancy low gas permeability | fuel applications | -20 - 200 |
| FVMQ | fluorosilicone rubber | very good chemical resistance to hydrocarbons, mineral oils and fuel | -55 - 175 | |
| HNBR | hydrogenated nitrile butadiene rubber | properties comparable to NBR with higher operating temperatures | parts in contact with mineral oil, diesel and cooling water | -30 - 140 |
| IIR | isobutene-isoprene rubber | very low permeability to air, water vapor and gases good weather, ozone, organic and inorganic chemicals and aging resistance |
tires | -40 - 110 |
| NBR | nitrile butadiene rubber | oil resistant (depends on acrylonitrile content) good mechanical propertties good abrasion resitance |
mineral oil and grease seals | -30 - 100 |
| PUR | polyurehanes | properties varies with widely with the chemical recepie - typical very good low temperature flexibility, good recovery performance, low gas permeability, good mineral oil resistance and high strength | adhesives or glues parts like seat cushions, exterior elements in cars soundproofing suspension insulators |
-50 - 110 |
| SBR | styrene butadiene rubber | very good mechanical properties abrasian resistance |
tires v-belts |
-40 - 110 |
| VMQ | silicone rubber | high thermal resistance very flexible at low temperatures resistant to oils and water vapor good weather resistance good dielectric properties hydrophobic |
seals in electric applications, radiators | -50 - 200 |
