UV radiation is commonly used in germicidal lights in hoods and is a component of sunlight. UV radiation will have a serious deleterious effect on most plastics, especially the polyolefins, including polyethylene (low-density polyethylene [LDPE] or high-density polyethylene [HDPE]); polypropylene (PP), and polymethylpentene (PMP); and acrylics. Polystyrene (PS), polycarbonate (PC) and polyethylene terephthalate G copolymer (PETG) can withstand limited UV exposure. In general the effects of UV can be seen as a color change, usually a darkening or yellowing, combined with an embrittling effect.
