Silicone cooking utensils have a high degree of heat resistance. So extremely high temperatures are no problem (a few companies claim heat resistance of over 300 degrees celsius). In addition, you won't have to think about silicone turners or whisks melting if you forget them in the pan for a long time.
When I was younger, I remember using non-stick turners that melted when immersed in boiling oil. Silicone potholders are even available for use when removing a dish from an extremely hot oven.
