Gukoresha dioxyde ya titanium (TiO ₂) mu nganda za pulasitiki bigaragarira cyane muri ibi bikurikira: nk'ibara ry'ibanze, rishobora kunoza cyane umweru n'imbaraga zo gutwikira ibicuruzwa bya pulasitiki, rigatuma urumuri rugaragara cyane binyuze mu gukwirakwira no kwinjiza urumuri, cyane cyane mu ma resins ahora asa n'umuhondo, agace gato ka titanium dioxyde ifite umurambararo wa 0.15-0.3 μ m gashobora gukora ibara ry'ubururu inyuma kugira ngo ryongere ingaruka zo gutwikira; Muri icyo gihe, dioxyde ya titanium itinda gusaza kwa pulasitiki kandi ikongera ubushobozi bwo guhangana n'ikirere binyuze mu kwinjiza urumuri rwa ultraviolet. Ibikoresho byo hanze bigomba gukoresha ubwoko bwa rutile kandi bikongerwamo ikoranabuhanga ryo gutunganya ubuso nka silicon, aluminium, na zirconium kugira ngo hirindwe ibibazo by'imyobo iterwa no gushonga kw'amazi mu gihe cyo gutunganya ubushyuhe bwinshi; Ku bijyanye no kudahindagurika kw'ubushyuhe, dioxyde ya titanium ishobora kunoza imikorere ya pulasitiki mu bidukikije bishyuha cyane binyuze mu kugabanya ibikorwa bya fotochemical binyuze mu buryo bwo guhindura ubuso (nk'imyambaro idakora), kwemeza imbaraga za mekanike n'ubudahangarwa bw'amabara y'ibicuruzwa mu bihe bigoye. Ingamba zo gukoresha titanium dioxide ziratandukanye ku bwoko butandukanye bwa pulasitiki - polyolefini zisaba kwitabwaho ku buryo bwo gukwirakwira no kurwanya ibara, ibikoresho bikomeye bya PVC bishingiye ku bushobozi bwa titanium dioxide bwo kurwanya ifu, mu gihe ABS yibanda ku kuringaniza imiterere y'amatara n'iy'imashini. Mu mikoreshereze isanzwe, ingano ya titanium dioxide yongewemo igenzurwa kuri 3% ~ 5% kugira ngo ihuze ubukungu n'imikorere, kandi ubwinshi bw'amabara yihariye bushobora kugera kuri 40% ~ 70%; Mu kunoza ingano y'uduce duto (nk'ubugari bwa 2-35 μ m) no gutunganya ubuso, Bontecn Group China titanium dioxide yagize umweru mwinshi, ihangana n'ikirere, no kudahinduka mu buryo burambye mu nganda nka pulasitiki, inzugi n'amadirishya, n'ibice by'imodoka.
