What Factors Affect Glass Transition Temperature? Increase in pressure of surrounding leads to decrease in free volume and ultimately high Tg. Other factors like branching, alkyl chain length, bond interaction, flexibility of polymer chain, film thickness etc. also have significant impact on glass transition temperature of polymers. What do you mean by glass transition temperature
What Happens Above Glass Transition Temperature? There is a certain temperature(different for each polymer) called the glass transition temperature, or Tg 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. What will happen
What Does A High Glass Transition Temperature Mean? Above the Tg, the polymer is in the rubbery state. … For this polymer the service temperature should be below the Tg. This polymer is in the rigid, glassy state when it is being used at a temperature below the Tg. This means the polymer has high
