Polypropylene is especially sensitive to UV radiation. It degrades when exposed to light by an oxidative mechanism in which chain scission predominates over cross-linking.
Chain scission leads to an increase in crystallinity which in turn results in surface cracking. The formation of cracks leads to changes in appearance (color and gloss) as well as mechanical failure of parts. Articles for use both outdoors and indoors must be stabilized against UV light.

applications
PP Tapes
PP tapes are usually used in the form of woven or knitted fabrics such as shadow nets, soil covers, or different types of bags and sacks for packaging. A diiferent but growing application of tapes is artificial grass flooring fo decoration and sport.Tapes are usually made from cut and drawn films
applications
PP Fibres
There is a wide range variety of fiber applications which requires a good light stability such as:
PP fibres & staple fibers
Pp fibers & yarns
Pp spun bond nonwovens










applications
PP thick sections
For deeper layers of thic section parts, all UV adiations can be blocked with corporation of a UV absorber to prevent photo degradation. this serves to improve retention of mechanical properties after exposure.
