Gwiritsani ntchito
Chogulitsachi chimapereka chitetezo cha ultraviolet mu ma polima osiyanasiyana kuphatikizapo ma homo- ndi ma copolymer a styrene, mapulasitiki opanga monga ma polyester ndi ma acrylic resins, polyvinyl chloride, ndi ma polima ena okhala ndi halogen ndi ma copolymer (monga vinylidenes), ma acetal ndi ma cellulose esters. Ma elastomers, zomatira, ma polycarbonate blends, ma polyurethane, ndi ma cellulose esters ena ndi zinthu za epoxy.
Mlingo wokhazikika: zinthu zoonda: 0.1-0.5%, zinthu zokhuthala: 0.05-0.2%.
1.Polyester yosakhuta: 0.2-0.5wt% kutengera kulemera kwa polima
2. PVC
PVC yolimba: 0.2-0.5wt% kutengera kulemera kwa polima
PVC yopangidwa ndi pulasitiki: 0.1-0.3wt% kutengera kulemera kwa polima
3. Polyurethane: 0.2-1.0wt% kutengera kulemera kwa polima
4.Polyamide: 0.2-0.5wt% kutengera kulemera kwa polima
