What is Silicone & Why is It Used for Beer Stoppers?

“Silicone” is the general name for a family of polymers that includes any synthetic compound consisting of repeating units of siloxane. The most common form of silicone is silicone rubber, which is popular for a wide range of applications. Generally, silicone rubber is non-reactive, stable, resistant to fungal growth, and can be used in harsh environments and extreme temperatures (-75° to 450°F/-60° to 232°C) without losing its useful properties. Silicone maintains its dimensional tolerances at high temps, and won’t become brittle in subzero conditions.

Silicone rubber’s chemical and mechanical properties, along with the ease with which it can be molded, make it an ideal material for beer barrel stoppers. Ace Seal uses special, FDA-approved, food grade silicone for all our barrel bungs.
