Understanding the Coefficient of Linear Thermal Expansion (CLTE) for a Machined Polymer

February 2, 2021

What is Thermal Expansion (and Contraction)?   Thermal expansion or contraction occurs when a material is exposed to temperature change and thus leads to change in all dimensions, as well as other physical properties.  While this effect is most noticeable in gasses and liquids, it is also notable in solids.  Softer materials such as unreinforced polymers experience greater levels of dimensional change per each degree change in temperature.   When...
