UV327 irashobora gukurura cyane urumuri rwa ultraviolet 300-400nm, ituze ryimiti myiza, ihindagurika rito, guhuza neza na polyolefine, ihindagurika rito, uburozi buke, ntibishobora gutwikwa, nta ruswa, kubika neza, hamwe nubufatanye bukomeye na DLTDP (PS800). Irakwiriye cyane cyane kuri polymers zumva cyane imirasire miremire ya ultraviolet (urugero, polyimidite, polifhenyl sulfide) hamwe nibisabwa bisaba koherezwa muke kumirasire miremire ya ultraviolet (urugero, lens optique).
Ikoreshwa cyane cyane muri chloride ya polyvinyl, polystirene, resin idahagije, polyurethane, polymethyl methacrylate, polyethylene, ABS resin, fibre polypropilene, irangi, ibara ryamabara, ibifunga hamwe nizindi polymers nizindi nzego nyinshi.
Bipakiye muri 20 cyangwa 25 Kg / ikarito. Cyangwa bipakiye nkuko abakiriya babisabwa.
Ubike ahantu hakonje, humye kandi uhumeka; irinde izuba.
Nyamuneka twandikire ibyangombwa byose bijyanye.
Uruganda rushya rwa Venture rwiyemeje gutanga urumuri rwiza rwo mu rwego rwo hejuru kugira ngo ruhuze ibyifuzo bitandukanye by’inganda, gutwara udushya no kuramba mu iterambere ry’ibicuruzwa, nyamuneka twandikire:
