Mylar glass transition temperature
WebThere is a certain temperature (different for each polymer) called the glass transition temperature, or T g for short. When the polymer is cooled below this temperature, it becomes hard and brittle, like glass. Some polymers are used above their glass transition temperatures, and some are used below.
