1.Organic polymer inobatsira antioxidant.
2.Reduce melt flow rate (MFR) kuti ipende panguva yepolymer thermal processing.
3.Iine yakanaka synergistic effect ine yakavharidzirwa phenolic antioxidant 1010,1076,313,114, nezvimwewo, uye inogona kupawo kusanganiswa kwezvinhu zvina zviri pamusoro apa.
4.Inogona kushandiswa pamwe chete ne benzotriazole UV absorbers uye inodzivisa amine photostabilizers muzvigadzirwa zvekunze.
Inoshandiswa zvakanyanya mu polyolefin (senge polyethylene, polypropylene) uye olefin copolymer, polyamide, polycarbonate, PS resin, PVC, engineering mapurasitiki, rabha uye petroleum zvigadzirwa, ABS resin uye zvimwe zvinhu zvepolymer. Complexes inogona zvakare kushandiswa mukunamira, yakasikwa kana synthetic adhesive resin, nezvimwe.
Wedzera huwandu: 0.1% ~ 1.0%, iyo chaiyo yekuwedzera mari inotemerwa zvinoenderana nemutengi application bvunzo.
Yakarongedzwa mu20 Kg / 25 Kg katoni / aluminium foil bag.
Kana kurongedza sezvinodiwa nemutengi.
Chengetedza zvakakodzera munzvimbo yakaoma iri pasi pe25 C ine hupenyu hwesherufu hwemakore maviri.
Ndapota taura nesu kune chero magwaro ane hukama.
