What is Silicone & Why is It Used for Bungs?

“Silicone” is the general name for a family of polymer materials that includes any synthetic compound that consists of repeating units of siloxane. The most common form of silicone, silicone rubber, can be found in a huge array of applications. Silicone rubber is non-reactive, stable, and resistant to fungal growth. It can also be used harsh environments and extreme temperatures (-75° to 450°F/-60° to 232°C), as it doesn’t become brittle in subzero conditions and maintains its dimensional tolerances at high temps.

Silicone rubber’s beneficial chemical and mechanical properties, and the ease of manufacturing and molding this material, make it perfect for beer barrel bungs. Ace Seal uses specialized, FDA-approved food grade silicone for all our barrel stoppers.
