Silicone rubber has historically been used in specialty applications in order to meet requirements other elastomers cannot. Silicones have the largest application temperature span of all rubbers, -120 F to +500 F, with one or two exceptions where highly specialized and costly Fluoropolymers can compare.

Silicones are environmentally friendly in that they do not consume oil based produces in their formulation and tend to outlast all other alternatives in high temperature applications.

The US military applies the longest shelf life criteria to Silicone rubber components. For example, a coolant hose made with Silicone meeting SAE J20 specification is given a shelf life of 20 years, whereas those made with chloroprene rubber meeting SAE J20 are given a shelf life of 8 years.

The benign nature of this rubber makes components made with Silicone ideal for electronic applications, where long life and chemical inertness are essential to good electrical integrity over the component’s life. Silicone rubber parts can be made extremely conductive (resistivity of 0.0001Ω cm) or highly isolative (resistivity of 1015Ω cm).

In the turbo Diesel engine market, silicone rubber is commonly used on the charged air cooler (CAC) components in order to survive the severe temperatures. It is also used in the coolant system as radiator and heater hoses for superior service life and where those hose application are plumbed near hot components such as the exhaust system.
