Silicone insulation

FAQ 30.04.2023

Does silicone insulate?

Silicones offer excellent electrical insulation properties and can be formulated in various ways to meet different needs. Silicones offer several advantages to ensure electrical and electronic insulation in areas such as industrial assembly, both upstream in the manufacturing process and downstream in terms of the reliability and durability of finished products.

Encapsulation and Potting Electronics with Silicone Solutions

Simply put, silicone-based products used in gasketing, bonding, potting and encapsulation of electronic components in industrial assembly get the job done because they can be formulated to meet very specific insulation requirements, such as the right balance between dielectric strength or electrical conductivity.

Therefore, silicone elastomers are used in high-performance applications, especially in harsh environments, where other polymeric materials will fail. They ensure reliable and durable insulation over a wide range of temperatures (from -50°C to 250°C) and extreme environmental exposure (humidity, UV, ozone).

Silicones also control the entire temperature management system of power systems by optimizing the trade-off between heat and power transfer, conduction and convection, thus reducing thermal runaway, while ensuring safety.

What is silicone?

Silicone is an inert synthetic compound that come in a variety of forms (oil, rubber, resin). Typically, heat-resistant and rubber-like, they are present in sealants, adhesives, lubricants, medical applications, cookware and insulation. Silicone is a polymer that contains silicon, combined with carbon, hydrogen and oxygen and, in some cases, other elements.
