QUINIZARIN Resistant O-Rings and Seals
Quinizarin, also known as quinine tartrate, is a white crystalline powder composed of two forms of quinine, an alkaloid derived from cinchona bark. It is widely used in the pharmaceutical industry and has a variety of applications, such as in the production of antimalarials, tonics, and as a food additive.
When rubber is exposed to quinine tartrate, it can cause a number of types of failures. For example, exposure can cause rubber to become brittle, swell, or change color. Furthermore, exposure can cause rubber to become weakened and more prone to cracking. In some cases, quinine tartrate can cause rubber to degrade and even decompose.
