**RECOMMENDED FOR
|
|
Buna N |
(Nitrile)
Widely used elastomer offering excellent resistance to most oils, silicone
greases, hydraulic fluids, water and alcohols. Temperature range: -40º to +250ºF. |
COLD WATER
GREASES OILS ALCOHOL PETROLEUM FLUIDS |
| Neoprene* | (Chloroprene)
Exhibits moderate resistance to petrolium based fluids. Good resistance
to weathering and ozone. Good resiliance low compression set. Temperature range: -40º to +250ºF. |
AMMONIA
MILD ACID FREON |
| Silicone | Used
for wide temperature ranges and dry heat resistance. High resistance to
sun and ozone injury. Poor tensile, tear, and abrasion resistance and
high friction traits. Is fungus resistant, odorless, tasteless, and toxic. Temperature range: -75º to +450ºF. |
HIGH TEMP
COLD TEMP OZONE FDA LOW OUTGASSING |
| Viton* | (Fluorocarbon)
excellent mechanical and physical properties. Used in high temp and chemical
service. Fuels, grease, acids, solvents, sun and ozone resistance. Has
low gas permeability. Temperature range: -20º to +400ºF. |
VACUUM |
| EPR | (EPDM
- Ethylene Propylene) Used for hot water, steam, milds acids, alkalis,
some solvents, and has excellent sun and ozone resistance. Temperature range: -60º to +300ºF. |
GREASES
ALCOHOL KETONES MILD ACID OZONE |
| Fluorosilicone | Used
when high and low temperatures and harsh chemical and solvent resistance
is required. Especially for aerospace industry. Temperature range: -75º to +400ºF |
HIGH / LOW TEMP SOLVENTS
FUELS OILS OZONE |
| Teflon* | Excellent
resistance to high and low temperatures, solvents, acids, fuels, oils,
and ozone. Teflon* is a chemically inherent material. Problems with poor
elastic memory, poor tear strength and tendency to cold flow with time.
Teflon* coated and Teflon* encapsulated also availible. Temperature range: -300º to +450ºF. |
HIGH / LOW TEMP
ALL CHEMICALS FUELS OZONE |
| Chemraz* | Same
temperature and chemical attributes as in Teflon* with other elastomers.
Excellent resistance to steam and hot water. Temperature range: -20º to +450ºF. |
HIGH TEMP
ALL CHEMICALS STEAM / HOT WATER |
| EMI | Both solid and hollow rings are available in electrically conductive compounds. Offers superior shielding capability. |
ELECTRICALLY CONDUCTIVE
