Why siliconization is doing for Rubber bungs.

What is mean by siliconization and Its benefits?

Siliconization on a rubber bung is a process of coating or treating the surface of a rubber bung with a layer of silicone material. This silicone layer serves several purposes:

  1. Lubrication: It reduces friction and makes it easier to insert and remove the bung from a container, such as a vial.
  2. Reduced Friction: Siliconization reduces the friction between the rubber stopper and the interior surface of the container it is inserted into. This makes it easier to insert and remove the stopper from the container.
  3. Sealing: Silicone-coated bungs create a tight seal when inserted into a container, preventing the escape of gases or liquids.
  4. Chemical Resistance: Silicone provides resistance to chemicals, which helps protect the rubber bung from degradation when it comes into contact with various substances. Moreover Silicone is known for its resistance to various chemicals, including acids, bases, and organic solvents.

In short, siliconization of a rubber bung involves adding a silicone layer to improve its functionality in sealing and handling applications.
