Materials
|
|
 |
|
| Viton® (FKM) |
| The most specified material with temperature resistance to 200°C as well as resistant to aggressive fuels, acids, and other chemicals. Excellent compression set resistance Used in the semiconductor, chemical processing industries, and many others. |
|
|
| |
|
| |
 |
|
| Ethylene Propylene Rubber (EPDM) |
| EPDM has a temperature range of -50°C to +120°/150°C, depending on the curing system. It has great resistance to heat, water and steam, alkali, mild acidic and oxygenated solvents, ozone, and sunlight. Also resistant to alcohols, glycol engine coolants and SKY-DROL (phosphate ester hydraulic fluid). |

|
| |
 |
|
| Silicone (VMQ) |
| Silicone rubber is generally non-reactive, stable, and resistant to extreme environments and temperatures from -50°C to +232°C while still maintaining its useful properties. Silicone compounds are very clean and are used in many food and medical applications. |
|
|
| |
|
| |
 |
|
| Buna-N/Nitrile (NBR) |
| Due to its excellent resistance to petroleum products, and its ability to be compounded for service over a temperature range of -35°C to +120°C, nitrile is the most widely used elastomer in the seal industry today. |
|
|
| |
|
| |
 |
|
| Neoprene (CR) |
| It is moderately resistant to both petroleum oils and weather (ozone, UV, oxygen). Neoprene is classified as a general purpose elastomer which has relatively low compression set, good resilience and abrasion, and is flex cracking resistant with a temperature range of -30°F to 212°F. It is used extensively for sealing refrigeration fluids due to its excellence resistance to Freon® and ammonia. |

|
| |
|
| |
 |
|
| Teflon® (PTFE) |
| 100% virgin PTFE which has the lowest coefficient of friction (against polished steel) of any known solid material. PTFE is very non-reactive, its melting point is 327 °C, but its properties degrade above 260 °C. |
|
|
| |
|
| |
| ePTFE |
| Expanded PTFE's resistance to chemicals and abrasion, combined with its ability to withstand high and low temperature extremes from -268oC to 315o C, makes it highly effective in the transport and sealing of industrial fluids and cryogenic applications. |
