Gwiritsani ntchito
Izi zimapereka chitetezo cha ultraviolet mu ma polima osiyanasiyana kuphatikiza ma styrene homo- ndi copolymers, mapulasitiki a engineering monga ma polyesters ndi ma acrylic resins, polyvinyl chloride, ndi ma halogen ena okhala ndi ma polima ndi ma copolymers (mwachitsanzo vinylidenes), acetals ndi cellulose esters. Elastomers, zomatira, zomatira za polycarbonate, polyurethanes, ndi ma cellulose esters ndi zida za epoxy.
General mlingo: woonda mankhwala: 0.1-0.5% , wandiweyani mankhwala: 0.05-0.2%.
1.Unsaturated Polyester: 0.2-0.5wt% kutengera kulemera kwa polima
