Does heat melt silicone?

While most plastics will begin to melt at high temperatures, silicone does not have a melting point and remains solid until combustion occurs. At high temperatures (200-450oC), silicone rubber will slowly lose its mechanical properties over time, becoming brittle.Dec 9, 2017

How many types of silicone sealants are there?

Silicone sealants typically fall into one of two main categories, namely neutral cure and acid cure (or acetoxy) variants.

Is there heat resistant plaster?
