Silicone rubber properties:
The application range of Silicone rubber MVQ is determined by its wide temperature range: it demonstrates steady performance in both very low and very high temperatures (-55°С to +200 °С), but is not suitable for usage in hot water and/or steam. Its oil resistance is similar to that of NBR rubber, but its mechanical properties are considerably worse than those of NBR.
Advantages:
- excellent temperature resistance: -55°С to +200 °С
- best heat resistance of all rubber types
- best cold resistance of all rubber types
- excellent weather and ozone resistance
Limitations:
- poor tensile and tear strength
- poor wear resistance
- sensitivity to hydrolysis
- poor resistance aganst aromatic oils and oxidized mineral oils
- poor diffusion resistance
