UV327 inogona kunyatsotora 300-400nm ultraviolet mwenje, yakanaka kugadzikana kwekemikari, kuderera kuderera, kuenderana kwakanaka ne polyolefin, yakaderera inoputika, yakaderera muchetura, isingabatike, isina ngura, yakanaka kuchengetedza kugadzikana, uye yakakosha synergy neDLTDP (PS800). Iyo inonyanya kukodzera mapolymers anonyanya kunzwisiswa neakareba wavelength ultraviolet mwaranzi (semuenzaniso, polyimidites, polyphenyl sulfide) uye maapplication anoda yakaderera transmittance kune refu wavelength ultraviolet nemwaranzi (semuenzaniso, optical lens).
Inonyanya kushandiswa mu polyvinyl chloride, polystyrene, unsaturated resin, polyurethane, polymethyl methacrylate, polyethylene, ABS resin, polypropylene faibha, pendi, coloring agent, adhesives uye mamwe mapolymers uye mamwe akawanda minda.
Yakarongedzwa mu20 kana 25 Kg / katoni. Kana kurongedzwa sezvinodiwa nevatengi.
Chengetedza munzvimbo inotonhorera, yakaoma uye ine mhepo; dzivisa chiedza chezuva chakananga.
Ndapota taura nesu kune chero magwaro ane hukama.
New Venture Enterprise yakatsaurirwa kupa emhando yepamusoro mwenje stabilizer kusangana nezvinodiwa zvakasiyana zvemaindasitiri aya, kutyaira hunyanzvi uye kusimba mukuvandudza zvigadzirwa, ndapota taura nesu:
