High Temperature Rubber Gaskets Material

Effects of Temperature

Operating temperatures of the project will have a profound effect of the longevity of the elastomer and rubber seals. If the proper material is not select for the intended operational temperature ranges the possibility of product failure increases.

Exceeding temperature limitations of product can lead to one or several of the following:

• Increased hardening

• Product becomes more brittle

• Loss of resilience

• Material cracking

• Excessive wear and tear

• Deformation of original shape

• Degradation of physical strength

• Swelling of material

Temperature will have a significant effect on the overall performance of the product. Cold temperatures could also reduce seal size and possibly leak due to reduce contact surface. Lower temperatures could also affect flexibility and make material brittle. If temperature limitations are exceeded, the change in these characterizations will increase the failure rate of the component and possibly hinder overall performance of your project.
