Gwiritsani ntchito
Izi ndi stabilizer kuwala ndi ntchito zabwino, amatha kuyamwa UV cheza 240-340 nm wavelength ndi makhalidwe a kuwala mtundu, nontoxic, ngakhale zabwino, kuyenda yaing'ono, processing zosavuta etc. Ikhoza kuteteza polima mpaka pazipita zake. , kumathandiza kuchepetsa mtundu.Ikhozanso kuchedwetsa chikasu ndikulepheretsa kutaya kwa thupi lake.Amagwiritsidwa ntchito kwambiri ku Pe, PVC, PP, PS, PC organic galasi, polypropylene CHIKWANGWANI, ethylene-vinyl acetate etc. Komanso, ali ndi zabwino kwambiri kuwala-bata zotsatira kuyanika phenol aldehyde, varnish mowa ndi acname, polyurethane, acrylate. , expoxnamee etc.
Mlingo wamba
Mlingo wake ndi 0.1% -0.5%.
1.Polypropylene: 0.2-0.5wt% kutengera kulemera kwa polima
2.Zithunzi za PVC
PVC yolimba: 0.5wt% kutengera kulemera kwa polima
PVC yapulasitiki: 0.5-2 wt% kutengera kulemera kwa polima
3.Polyethylene: 0.2-0.5wt% kutengera kulemera kwa polima
Kulongedza ndi Kusunga
Phukusi: 25KG/CARTON
Kusungirako: Kukhazikika pamalopo, kusunga mpweya wabwino komanso kutali ndi madzi ndi kutentha kwakukulu.
