In this episode, we dive into carbon graphite — the most important soft face material in mechanical seals.
It works as a soft, wear-resistant ring, commonly paired with tungsten carbide, silicon carbide, or ceramic.
Soft against hard means less wear and longer life.
Graphite works best in clean media like clean water and oil.
To make it tougher, we use impregnation — resin (up to 250°C), metal (over 400°C), or furan resin (acid/base resistant).
Choosing the right impregnation makes all the difference.
