NBR |
-34°F to +212°F |
40 to 90 |
|
|
|
|
Nitrile Buna-N (NBR) is one of the most common and widely used sealing materials because of its excellent sealing and mechanical properties at a low cost. Nitrile offers excellent tensile strength, abrasion resistance, tear resistance, and compression resistance. Optimal environments include petroleum oils and fuels, silicone oils and greases, propane, ethylene glycol, butane, vegetable, mineral oils and greases, dilute acids, and water and steam applications (below 212°F). |
AU |
-40°F to +180°F |
40 to 90 |
|
|
|
|
Urethane, polyurethane (AU) is produced by the poly addition reaction of a polyisocyanate with a polyol in the presence of a catalyst. AU has excellent wear resistance, high tensile strength, tear strength, extrusion resistance and elasticity in comparison with any other material. Can be used with propane, butane, mineral oil and grease, silicone oil and grease. |
EPDM |
-70°F to +300°F |
40 to 95 |
|
|
|
|
Ethylene propylene can be used in water and steam (up to 300°F), glycol based brake fluids, silicone-based break fluids, many organic and inorganic acids, cleaning agents, sodium and potassium alkalis, phosphate ester based hydraulic fluids, silicone oil and grease, alcohols, ketones, esters and ozone. Not compatible with mineral oil products like oils, greases and fuels. |
FKM, Viton® |
-15°F to +400°F |
55 to 90 |
|
|
|
|
Fluorocarbon (FKM) offers excellent resistance to chemicals, oil, ozone and sunlight with a higher temperature range than nitrile, AFLAS, EPDM and some of the common industrial materials with an operating range up to 400° F. Can be used in petroleum oils and fuel, non flammable hydraulic fuels, acids, aircraft engine applications, synthetic hydraulic fluids, organic solvents, mineral and vegetable oil and grease, aliphatic hydrocarbons (butane, propane, natural gas), hard vacuum applications, silicone oils and greases, solvents and water or steam (up to 400°F). |
VMQ |
-65°F to +400°F |
20 to 80 |
|
|
|
|
Silicone (VMQ) elastomer is made from silicone, oxygen, hydrogen and carbon. Silicones are used in the medical and food industry because they do not have any odor or taste. VMQ is resistant to oxygen, ozone, UV light, mineral and vegetable oils, diluted salt solutions, engine and transmission oil, brake fluids (non petroleum base), fire resistant hydraulic fluid, high molecular weight chlorinated aromatic hydrocarbons. Good flexibility and compression set. |
PTFE, AFLAS |
-15°F to +450°F |
60 to 90 |
|
|
|
|
PTFE has excellent resistance to ozone and weathering along with a wide range of chemicals, including acid, base, and steam. A reliable choice for applications that work in tough environments. Applications include Automotive engine coolants, motor oils, some brake fluids, and steering fluids; food and pharmaceutical applications, wide temperature range. |
TPE |
-22°F to +500°F |
20 to 95 |
|
|
|
|
TPE is a true thermoplastic, which does not require vulcanization or curing. TPE exhibits high elasticity of thermoset vulcanized rubber at room temperature and good process-ability of thermoplastic at high temperature. TPE is naturally chemical resistant and can be made flame retardant as well. TPE is also eco-friendly, cost effective, and has melt properties. |
POM (Plastics) |
-121°F to +185°F |
80 to 95 |
|
|
|
|
POM plastic is a semi-crystalline thermoplastic used in precision parts that require high stiffness, low friction, and excellent dimensional stability. POM has high mechanical strength and rigidity, and is available in food-grade formulations that meet FDA, NSF, and 3-A Dairy material standards. |
