Description


1.     product Parameter (specification)


NBR resistance to temperature from -40 to 120 degree

The temperature ranges presented above are approximations for dry air service only and should not be 

used to determine design specifications or end-use temperature limits. Actual temperature range of a 

compound in an end-use application is highly dependent on part type, hardware configuration, applied 

forces, chemical media, pressure and thermal cycling effects, and other factors. The most practical way of 

determining an end-use temperature range is testing in the actual application conditions.
