Designing With Silicone Materials Series

Industry InSight is continuing to push the envelope by launching a new series of articles devoted to the design engineer: the Designing With Silicone Materials series. This series focuses on product design with silicone materials and provides valuable knowledge for even the most experienced design engineer. For more details about what this series will address, click here.

A Brief History of Siloxane Chemistry

Silicone compounds and materials comprise more than $10 billion annually in global sales and impact industries ranging from construction and cosmetics, to the healthcare and aerospace industries. While these versatile compounds have a long and intricate past, this quick synopsis of significant developments throughout silicone history provides insight into where and how these materials got their start.

Quality Control and Testing Methods: Work Time (Pot Life)

Some silicone systems are formulated with the intent to cure into a specific form. These silicones utilize reactive chemistries and contain crosslinkers and catalysts. In a previous issue of Industry InSight, we discussed the concept of viscosity to explain a material's feel; in this edition, we discuss the case of curing silicone systems and how viscosity can change rapidly when adding catalysts or exposing the system to a certain set of environmental conditions.
