WebThermal Expansion. Thermal expansion is the tendency of matter to change in shape, volume, and area in response to a change in temperature. Temperature is a monotonic function of the average molecular kinetic energy of a substance. Monotonic function is a function which is either entirely nonincreasing or nondecreasing. WebTech Tip– When polymers are required for applications that involve large changes in temperature, best practices involve selecting a filled grade of a stable (low CTE) base polymer. When fillers are added to highly stable …
