Designing With Silicone Materials Series Materials Requirements

This article is second in the series and is a follow up to the “Getting Started” article published in the Summer 2005 issue of Industry InSight. In the design process, applications that are needed for any given device must be identified. Moving parts in the design may mandate a lubrication solution, while different parts may require an adhesive for bonding, and so on. This article addresses the types of applications suitable for silicone, as well as the property requirements that must be considered.

Stress at Strain

Stress at Strain is a property that may be overlooked when considering the key physical properties associated with silicone elastomer systems. Related to the concept of modulus, stress-at-strain results are force values (like psi) reported at specific elongation values and can give users an idea of a cured elastomer's feel under specific conditions.
