A presentation on those specific elastomeric properties to be considered when selecting materials for use in Low Temperature applications. The use of low temperature test methods including Temperature Retraction and Brittleness Temperature to characterize the low temperature elastomeric properties and the change to these property values that may occur due to the particular hydraulic fluid used. The positive and negative affects of plasticizers used in elastomeric compounds. Considerations for the use of compression type seals as well as high tensile, wear resistant lip type seals. Other low temperature related factors such as compression set and thermal contraction due to cyclic temperature conditions.
