DuPont Kalrez Spectrum 7275 parts are a light brown product based on a proprietary crosslinking system targeted specifically for the chemical processing industry. It exhibits minimal swelling and improved retention of physical properties when exposed to aggressive chemicals, e.g., concentrated nitric acid, organosilanes, chlorosiloxanes, pure ethylene oxide, butyraldehyde, amines and vinyl and acrylic monomers.
It also has excellent compression set resistance and good retention of physical properties after aging at high temperatures. A maximum service temperature of 300 °C is suggested.
