Operating Temperature Ranges for Elastomers

Properties and Selection Notes

The Operating Temperature Range is a critical parameter for material selection in sealing and engineering applications. It defines the continuous service temperature window where the elastomer maintains its designed mechanical and chemical properties (e.g., elasticity, compression set resistance).

  • Upper Limit: Exceeding the maximum temperature typically accelerates degradation, leading to hardening, cracking, and loss of sealing force.
  • Lower Limit: Below the minimum temperature, elastomers can become brittle and lose their sealing ability due to stiffening.

Selecting an elastomer requires balancing the temperature range with other critical properties such as chemical resistance (to specific oils, fuels, or fluids), mechanical strength, abrasion resistance, and permeability.
