DEVELOPING FLUIDS Resistant O-Rings and Seals
Developing fluids, also known as “developers”, are solutions of organic compounds used in the photographic and printing industries to develop photographic film or plates. They are used to convert the latent image on the film or plate into a visible image. Developing fluids are typically composed of alkaline solutions containing chemicals such as sodium hydroxide, potassium carbonate, and potassium bromide.
When exposed to developing fluids, rubber materials can be degraded by the alkaline chemicals, leading to cracking, shrinking, and softening. This is especially true for rubber materials with low levels of natural antioxidants, such as EPDM and Nitrile. Additionally, some rubber materials are more resistant to developing fluids than others, so it is important to consider the specific material when selecting a rubber for photographic or printing applications.
