I-photostabilizer UV770 i-molecular weight low ithintele i-amine photostabilizer, eneempawu zokuhambelana kakuhle, ukuguquguquka okuphantsi, ukusabalalisa okulungileyo, ukuhamba okuphantsi, ukuzinza okuhle kwe-thermal kunye nokuzinza okuphezulu kwe-optical, kwaye ayifuni ukukhanya okubonakalayo kwaye ayichaphazeli umbala. Kumphezulu ophakamileyo kunye necandelo elishinyeneyo lebhendi emxinwa, ukubumba, kukho ukufotoseka okuhle kakhulu. Ngobunzima obuphezulu be-molecular stabilizer kunye ne-ultraviolet absorber, umphumo we-synergistic ubalulekile.
Isebenza kakhulu kwi: i-polyethylene, i-polypropylene, i-polystyrene, i-olefin copolymer, i-polyester, i-polyvinyl chloride ethambileyo, i-polyurethane, i-polyformaldehyde kunye ne-polyamides, i-adhesives kunye ne-seals njalo njalo.
Isixa esongezelelweyo esicetyiswayo: ngokubanzi 0.05-0.60%. Iimvavanyo ezifanelekileyo ziya kusetyenziswa ukumisela isixa esifanelekileyo esongezwa kusetyenziso oluthile.
Ipakishwe kwi-25 Kg / ibhokisi. Okanye ipakishwe ngokweemfuno zabathengi.
Gcina kwindawo epholileyo, eyomileyo kwaye engenamoya; kuphephe ukukhanya kwelanga.
Nceda uqhagamshelane nathi ngawo nawaphi na amaxwebhu anxulumeneyo.
I-New Venture Enterprise izinikezele ekuboneleleni nge-HALS ekumgangatho ophezulu ukuhlangabezana neemfuno ezahlukeneyo zala mashishini, ukuqhuba ukutsha kunye nokuzinza kuphuhliso lwemveliso, nceda uqhagamshelane nathi:
