WebThe slope of the curve below about 130 °C gives the thermal expansion coefficient for crystalline polyethylene, which is a hard plastic material. The volume expands sharply at the melting temperature. Above about 140 °C, the slope gives the thermal expansion coefficient of the plastic liquid. Thermal expansion coefficients are usually ... WebThermal Expansion From an atomic perspective, thermal expansion is caused by an increase in the average distance between the atoms. This results from the asymmetric curvature of the potential energy versus interatomic distance. The anisotropy results from the differences in the coulomb attraction and the interatomic repulsive forces.
