- Application Details
- ELASTOSIL R 755/60 OH is suitable both for extrusion of tubings and profiles and for compression, transfer and injection molding.
- Although most silicone rubbers show good resistance to boiling water, they degrade rapidly when subjected to superheated steam at temperatures of 160 °C and above (corresponding to 6 bar pressure).
- ELASTOSIL® R 755/60 OH resists steam at a temperature of 160 °C for over 2 months.
Properties

- Steam Resistance Properties
- Note
Cure conditions (post-cured 4 h / 200 °C) for cured properties:
- 1.5 % ELASTOSIL® AUX Crosslinker E (50% paste of bis-(2,4-dichlorobenzoyl)-peroxide in silicone fluid); 10 min / 135°C in press.
- 0.7 % ELASTOSIL® AUX Crosslinker C1 (Dicumylperoxide); 15 min /165 °C in press.
After steam immersion (1500 h / 140 °C in autoclave):
- Cure conditions: 0.7 % ELASTOSIL® AUX Crosslinker C1 (Dicumylperoxide), 15 min / 165 °C in press, post-cured 4 h / 200 °C for steam resistance properties.
