ChallengeFilms are directly harmed by substances that either influence the polymer chains of the plastics used or act as a catalyst to strengthen their decomposition reaction. Free radicals are generated in the polymers by UV radiation. Standard HALS cannot stop this reaction if they are deactivated by agrochemicals. The film becomes brittle.
POLYMER CHAINS GET DESTROYED,
THE FILMS BECOMES BRITTLE
HOSTAVIN® NOW PROTECTS AGRICULTURAL FILMSClariant's AddWorks AGC solutions based on the Hostavin® NOW technology not only offers high UV protection, but also strong resistance to pesticides. With this technology, the hindered amines are bonded to long alkyl chains, which are evenly distributed in the plastic of the agricultural film and remain there instead of migrating, i.e., moving to the surface of the film. The resultant HALS are stable to such an extent that they are not affected by aggressive pesticides. Therefore they retain their ability to neutralize free radicals formed by UV radiation and contribute in this way to significantly longer durability of agricultural films.
