Dimensional Stability to Heat

Articles manufactured with this product must not be continually exposed to temperatures above 60oC, depending on the application.

Ageing

The UV component of sunlight causes degradation to all plastics in general. This degradation depends on the exposure conditions, in other words, on the actual duration of exposure to sunlight, the sheet inclination to the sun’s rays, temperature and humidity and on sunlight intensity (geographical coordinates). This degradation shows up as a progressive yellowing, a reduction in light transmission and loss of mechanical properties. PET sheets are not protected against the effects of sunlight, however, the actual material itself possesses a certain resistance to outside weather so that it can be used in exterior applications in locations where sunlight is of low intensity and does not permanently fall on the sheets. For exterior applications where the sheets are permanently exposed to ultraviolet light, a stabilised product, which are protected on both sides, are recommended. When used in exterior applications, the protective film must be removed immediately, since exposure to sunlight can cause permanent adhesion to the sheet.
