What is Silicone & Why is It Used for Bungs?
“Silicone” is the general name for a family of polymer materials; it includes any synthetic compound that consists of repeating units of siloxane. Silicone rubber, the most common form of silicone, is used in a broad array of applications. Silicone rubber is, in general, non-reactive, stable, and resistant to fungal growth. It is well-suited to use in harsh environments and extreme temperatures (-75° to 450°F/-60° to 232°C), as these conditions do not compromise silicone rubber’s useful properties. It maintains its dimensional properties at high temps, and doesn’t become brittle in subzero temperatures.
The beneficial chemical and mechanical properties of silicone rubber, as well as the ease of manufacturing and molding this material, make it ideal for beer barrel bungs. Ace Seal uses special, FDA-approved, food grade silicone for all our barrel stoppers.
