1.Organic polima wothandizira antioxidant.
2.Reduce melt flow rate (MFR) kuti ipangike pakupanga polima matenthedwe.
3.Ili ndi zotsatira zabwino za synergistic ndi zoletsedwa za phenolic antioxidant 1010,1076,313,114, etc., ndipo zimatha kuperekanso kuphatikiza kwazinthu zinayi zomwe zili pamwambazi.
4.It angagwiritsidwe ntchito pamodzi ndi benzotriazole UV absorbers ndi kulepheretsa amine photostabilizers mu mankhwala panja.
Amagwiritsidwa ntchito kwambiri mu polyolefin (monga polyethylene, polypropylene) ndi olefin copolymer, polyamide, polycarbonate, PS utomoni, PVC, mapulasitiki engineering, mphira ndi mankhwala mafuta, ABS utomoni ndi zipangizo polima. Complexes itha kugwiritsidwanso ntchito zomatira, zachilengedwe kapena zomatira zomatira utomoni, etc.
Onjezani kuchuluka: 0.1% ~ 1.0%, kuchuluka kwake komwe kumatsimikiziridwa malinga ndi mayeso a kasitomala.
Odzaza mu 20 Kg / 25 Kg katoni / thumba zojambulazo aluminiyamu.
Kapena odzaza malinga ndi zofuna za kasitomala.
Sungani moyenera pamalo ouma osatsika 25 C ndi alumali moyo wa zaka ziwiri.
Chonde titumizireni zolemba zilizonse zokhudzana ndi izi.
