Using the Lucas Compression Stress Relaxometer, the effect of cycling heating and cooling on retention of sealing force of various elastomers is presented. The study includes the effect of exposure of the sealing material to air, engine coolant, and motor oil. Thermal expansion, stress relaxation, and polymer swell or shrinkage are related to sealing force retention. Variations in formulation vs sealing force retention are explored.
