Iyo Photestabilizer UV770 ndeyekudzika srewlar uremu hwekutungamira Kune iyo yakakwira nzvimbo uye iyo gobvu chikamu cheboka rakamanikana, kuumbwa, pane yakanaka pikicha. Nemhando yepamusoro yemulecular uremu hwechiedza uye ultraviolet abororber, synergistic maitiro akakosha.
Kunyanya kushanda kune: polyethyle, polypropylene, polystyrene, olefin copolyren, polyester, polyurethane, polyforthesedde uye polymaldehyehde uye polymaliche uye polyamidyd
Yakakurudzirwa Kuwedzerwa Mari: Kazhinji 0.05-0.60%. Miedzo yakakodzera ichashandiswa kuona huwandu hwakakodzera hwakawedzerwa mukushandiswa kwakati.
Yakarongedzwa mu25 kg / carton. Kana kutariswa senge pane vatengi zvinodiwa.
Chengetedza munzvimbo inotonhorera, yakaoma uye yakatsvedza; dzivisa zvakananga zuva.
Ndokumbira kuti ubate isu kune chero zvinyorwa zvine hukama.
New Venture Enterprise inotsaurirwa kupa HERE HERE HALS HERS yekusangana nezvinodiwa zvakasiyana zveaya maindasitiri, kutyaira uye kusimba kwekusimudzira kwechigadzirwa, ndapota taura nesu:
