The traditional practice of improving the weatherability of PVC white profiles has been to add rutile titanium dioxide, but it is also a UV absorber. However, with the change of regional climatic conditions, the new market standards put forward higher requirements on the weather resistance of products. This traditional practice has been difficult to meet.
ASA white profile special weathering agent is specially developed for the easy aging of PVC white profiles when used outdoors. It can effectively absorb the ultraviolet spectrum of sunlight continuously irradiated to the earth. At the same time, it can effectively inhibit the decomposition of PVC in the profile caused by thermal oxidation, protect the stability of PVC support, and achieve the light and heat oxidation resistance through the cyclical reciprocating form of energy conversion. Extended service life. The product has the characteristics of reasonable formula, stable performance, good effect, high efficiency and simple use.
