[China Packaging News] recently, BASF, the German Space Center (DLR) and NASA Goddard Space Flight Center developed a new tool that can accurately select appropriate plastic additives according to the predicted intensity of UV radiation, so as to prolong the service life of plastic products as much as possible

the global UV radiation map drawn by the scientists of the two institutions can accurately display the intensity of UV radiation in all regions. Manufacturers can take advantage of the past increase to realize the transformation and upgrading of reflective insulation and anti radiation insulation into the private economy, and now to promote the development and upgrading of the private economy. They optimize the amount of plastic additives and produce durable plastic products according to the special requirements of the region

BASF and DLR develop ultraviolet radiation mapping tools to extend the service life of plastic products

Dr. Volker Bach, head of BASF's global capability Center for plastic additives, said: "The new global UV radiometer tool helps BASF improve the accuracy of the expected service life of plastic products in specific environments and reduce the risk of product failure due to climatic conditions. In this way, we can help customers select the appropriate performance stabilization system and optimize the amount of additives to protect plastic materials."

ultraviolet radiation is the main factor for premature aging of plastic products under sunlight, and terminal applications in agriculture, construction or automobile will be affected. If BASF light stabilizer is correctly used in the formula, it can effectively prevent the harmful effects of UV radiation on plastics; However, manufacturers must accurately predict the intensity of UV radiation for the use location and expected service life of the product application

small changes in geographical location have a significant impact on the intensity of UV radiation, which will further affect the aging degree of plastics. For example, the ultraviolet radiation intensity in northern and central Europe is average, while the outdoor plastic product applications in southern Europe or Asia often suffer serious losses. In China, India, parts of Australia and the Mediterranean, the radiation level is close to that of the Sahara desert. For agricultural customers here, the stability of greenhouse film is particularly important

various influencing factors

dlr and NASA have developed a dynamic UV radiation modeling tool using the measured data of satellites and ground stations, which can be used to calculate the amount of solar UV radiation reaching the ground. The factors influencing UV radiation include time, season and geographical location. In addition, they must consider the spatial and temporal distribution of clouds, atmospheric ozone, snow, ice and topography. These are helpful to more accurately predict the local UV intensity and UV radiation flux density of saturated polyester resin polymerized with 4-butanediol (BDO). The new global UV mapping tool can be accurate to the urban level, revealing many microclimates caused by the rise of UV radiation - which were previously unknown

volker Bach explained: "UV radiation distribution and intensity information are very helpful to BASF - they can not only be used in the development of new plastic additives, but also be considered when I recommend light stabilizers to customers. For plastic product manufacturers, the advantage is that they can provide more accurate service life prediction and save costs for plastic products for long-term outdoor applications."
