Urushinge rwa Polyester (PET, terylene yunvise) rwumvaga umwenda utayungurujwe hamwe nubushobozi bwimbaraga nyinshi, kurwanya super abrasion, kurwanya aside nziza, urwego rwibiryo, kimwe mubikoresho byungurura ubukungu bikoreshwa cyane mubikorwa bitandukanye byinganda zikoreshwa mukusanya ivumbi. imikoreshereze (umwenda wo kuyungurura umukungugu wo gukuramo ivumbi).
Zonel Filtech hamwe nitsinda rinararibonye kandi rifite ubuhanga, gutunga imirongo igezweho yo gukubita inshinge hamwe nibikoresho fatizo byo mucyiciro cya mbere bituma urushinge rwa polyester rwumva umwenda wo kuyungurura uturutse muri Zonel hamwe nuburinganire bwikirere buringaniye hamwe nubunini, imbaraga zingana cyane, ubuso bworoshye kandi kurekura byoroshye umukungugu wumukungugu, uramba.
Ukurikije ibihe bitandukanye byakazi hamwe nibisabwa byoherezwa mu kirere, umwenda wa polyester urashobora guhitamo uburyo butandukanye bwo kurangiza, nk'amazi yangiza amazi n'amavuta, ubwogero bwo guhagarika PTFE, membrane ya PTFE yanduye, ibyuma byerekana umuriro nibindi kugirango ukore iyi myenda iyungurura kugirango ikusanyirize hamwe ivumbi hamwe imikorere yo kuyungurura.
