A polymer part can comprise: a first layer comprising a first polymer, wherein the first layer allows greater than or equal to 5% of visible light to transfer through it; and optionally a second layer comprising a second polymer; wherein the second layer is opaque; wherein the polymer part comprises a phase change material, wherein when exposed to cyclic temperature and solar radiation conditions for a period of time, the polymer part has a lower effective temperature as compared to a polymer part without a phase change material when exposed to the same cyclic temperature and solar radiation conditions for the same period of time. |
