The coefficient of thermal expansion is defined as the change in length or volume of a material for a unit change in temperature. The overall coefficient is the linear thermal expansion (in.) per degree Fahrenheit or Celsius. The CTE data is calculated by the change in length divided by the quantity of the length at room temperature, multiplied Coefficient of Linear Thermal Expansion (CLTE):Formula Linear Coefficient of Thermal Expansion Values of Several Plastics The Coefficient of Linear Thermal Expansion (Or Linear Coefficient of Thermal Expansion) lies between (in the service temperature range for each case):Ca. 0.6 x 10-4 to 2.3 x 10-4 K-1 for most of the thermoplastics; Ca. 0.2 x 10-4 to 0.6 x 10-4 K-1 for thermosets
