Question

What does glass transition temperature effects on hardness?

Answer 1

Answer:

behaviour. Glass transition temperatures are very variable ranging from 140 °C to 370 °C according to the grades, curing process and the moisture content: For a defined grade, the glass transition temperature increases from 50 °C during post cure. ... 92–98% at 60 °C.

Answer 2

Answer:

The glass transition temperature is the temperature range where the polymer substrate changes from a rigid glassy material to a soft (not melted) material, and is usually measured in terms of the stiffness, or modulus. From: Talanta, 2002.
