Measurement of UV-Degraded Polymer Materials Using a Thermal Analyzer

User Benefits

- The change due to UV degradation of polypropylene and polyethylene, which are typical polymer materials was measured. In thermal analysis, changes in thermal properties such as melting and decomposition temperature can be evaluated. - The degraded part caused by ultraviolet irradiation is the sample surface layer, but the difference can be confirmed without sampling only the surface.

Introduction

Generally, resin and polymer materials are known to deteriorate due to heat and ultraviolet rays. Resin products used outdoors, in particular, must be resistant to ultraviolet rays. This article introduces the data measured by differential scanning calorimeter (DSC), differential thermal/ thermogravimetric analyzer (DTG), and Fourier transform infrared spectrophotometer (FTIR) regarding the effect of ultraviolet irradiation (UV irradiation) on polypropylene (PP) and polyethylene (PE), which are typical polymer materials.
