A silicone rubber band heater is a type of flexible heater that uses a silicone rubber band as a heating element. When you apply heat to a silicone rubber band heater, the silicone rubber band will expand and become more pliable, allowing it to conform to the shape of the object it is heating.

As the silicone rubber band heater continues to heat up, it will transfer heat to the object it is attached to. The temperature of the silicone rubber band heater will depend on the wattage and voltage of the heater, as well as the temperature setting.
Silicone rubber band heaters are designed to withstand high temperatures, typically up to 250°C (482°F). At these temperatures, the silicone rubber band will continue to expand and become more pliable, but it will not melt or degrade.

It's worth noting that silicone rubber band heaters are designed to be used with specific types of objects, and the exact behavior of the heater will depend on the object being heated. The temperature and duration of the heating process will also affect the performance of the silicone rubber band heater.
