Silicone Degradation Over Time - What's a Silicone Lifespan?
Using the above 'ready reckoner' formula, and using it in reverse, we can then work out an approximate life in service at 150°C. LIS Continuous @ 200°C = 6 weeks. LIS Continuous @ 190°C = 12 weeks. LIS Continuous @ 180°C = 24 weeks and so on. I have worked out that LIS Continuous @ 150°C would be around 190 weeks.
