“In-situ mix” and “ex-situ mix” are terms used to describe the process of mixing silicone rubber compounds.

In-situ mix refers to the process of mixing the silicone rubber compound directly at the manufacturing site or application location. This involves combining the base silicone material with various additives and catalysts to form a uniform mixture, which is then applied or molded in the desired shape. The in-situ mix approach is often used for applications where a precise, custom mix is required, or where the material needs to be applied in hard-to-reach areas.

On the other hand, ex-situ mix refers to the process of pre-mixing the silicone rubber compound before it is transported to the manufacturing site or application location. This involves combining the base silicone material with various additives and catalysts in a controlled environment, typically in a factory or laboratory. The pre-mixed material is then packaged and transported to the desired location for application or molding. Ex-situ mix is commonly used for large-scale applications, such as construction or industrial projects, where consistent material properties and high production volumes are required.
