Thermal resistance property Strathane is a very good insulator but a poor conductor of heat. This fact must be taken into account when designing parts for dynamic applica ons involving internal hea ng.

Water resistance Depending on the type, polyether elastomers are resistant to the effects of water immersion and have excellent long-term stability in water up to 50 °C. Use in hot water above 80 °C is not recommended for standard systems. Water absorp on is very low, 0.3 to 1.0 % by weight. Chemical resistance Strathane is a material that is generally resistant to chemicals. Depending on our formula ons, M/R/U series, polyether or polyester, we can communicate the specific resistance of each chemical component. Radia3on resistance Strathane elastomers are considered to have a beEer...

Frequency of stockes The number of races/minute in dynamic con nuous use must be always taken into account. An increase of the speed corresponds to a decrease of the % of compression. By staying below the limit value, the longevity increases because of the low hea ng (Hysteresis). Temperature resistance The opera ng range is – 20° C to + 80° C For short term – 40° C to + 120° C are Possible. Any material subjected to a deforma on and an internal fric on warms up. The characteris cs of the spring are determined by the module of elas city according to the temperature and geometrical shape The...
