Choosing a seal material for Ddt (dichlorodiphenyltrichloroethane)
The table above rates every common O-ring elastomer for service in Ddt (dichlorodiphenyltrichloroethane) on an A–D scale. A is Excellent, B is Good, C is Fair (test before relying on it), and D is Not Recommended. An X indicates insufficient published data.
For Ddt (dichlorodiphenyltrichloroethane), the strongest candidates are Hydrogenated Nitrile, Fluorocarbon (Viton), Perfluoroelastomer, Fluorosilicone. These ratings are representative at ambient conditions (~20°C). Compatibility shifts with temperature, concentration, pressure and exposure time, so always validate the material against your real operating envelope before committing to a design.
