1.Monga organic polymerization wa waukulu antioxidant.
2. Polima processing ndondomeko imayenera antioxidant, makamaka ntchito kuchepetsa mamasukidwe kukhuthala kusintha ndi mapangidwe gel osakaniza.
3. Perekani kukhazikika kwa kutentha kwa nthawi yaitali, posungira ndi kugwiritsa ntchito mankhwala omaliza kuti apereke chitetezo cha nthawi yaitali cha zinthu zakuthupi.
4. Iwo ali wabwino synergistic zotsatira ndi ena co-antioxidants.
5.In mankhwala panja angagwiritsidwe ntchito ndi benzotriazole ultraviolet absorber ndi oletsedwa amine kuwala stabilizer.
Amagwiritsidwa ntchito kwambiri mu polyethylene, polypropylene, polyformaldehyde, ABS resin, polystyrene, polyvinyl chloride mowa, mapulasitiki a engineering, synthetic fibers, elastomers, zomatira, phula, mphira wopangira ndi mafuta amafuta.
Kuchuluka kowonjezera: 0.05-1%, kuchuluka kwake komwe kumatsimikiziridwa malinga ndi kuyesa kwa kasitomala.
Onyamula 20Kg/25Kg thumba kapena katoni.
Sungani m'njira yoyenera pamalo owuma ndi mpweya wabwino pansi pa 25 ° C kupeŵa kukhudzana ndi zozimitsa moto.Alumali moyo wa zaka ziwiri.
