DuPont™ Kalrez® 1045 perfluoroelastomer parts are a specialty white product that is reinforced with a mineral filler that is highly resistant to oxidizing environments (carbon black-filled products may be affected by black degradation in oxidizing media). Typical applications include sealing rocket propellants, hot oxidizing acids, wet halogens and halogenated gases. A maximum continuous service temperature of 260 C (500 F) is suggested. Performance Features/Benefits: - Excellent resistance to highly oxidizing media, i.e., nitrogen tetroxide (N2O4), etc.
- Excellent resistance to hot oxidizing acids, i.e., red fuming nitric, etc., wet halogens and halogenated gases
- Good mechanical strength properties
- Good thermal stability
- Good compression set resistance
