The coefficient of linear thermal expansion measures the change in length per unit length of a material per unit change in temperature. Expressed as in/in/°F or cm/cm/°C, the CLTE is used to calculate the dimensional change resulting from thermal expansion. CLTE is especially important when components of an assembly have widely varying thermal expansion coefficients. Thermal expansion of a material is another important design factor, particularly in applications where plastic parts composed of Bayblend ET1000 resin are mated with metal parts or parts having metal inserts. Coefficient of linear thermal expansion was measured on injection molded samples according to ASTM D 696. Injection molding of these samples provided better consistency on repeat testing than values from sheet-extruded samples, though the numbers were close. Molding under ISO conditions minimizes molded-in orientation and results in more accurate values.

What factors contribute to the material with a higher coefficient of thermal expansion expanding more when exposed to heat compared to a material with a lower coefficient of thermal expansion?
Materials with a higher coefficient of thermal expansion expand more when heated because they have weaker atomic bonds, allowing the atoms to move more freely and increase in volume. In contrast, materials with a lower coefficient of thermal expansion have stronger atomic bonds, restricting their movement and resulting in less expansion when heated.
