Silicone and Fluorosilicone are just some of the compounds we use and the Custom Rubber compounding (formulations) are specifically made for your application. Although we have many “standard” materials, every part has a specific formulation. We have over 150 existing formulas to choose from. Should one of these not meet your needs, we will gladly formulate a new compound for your application without a special “set-up charge.”
