ʻO Chimassorb 944 Cas 71878-19-8
ʻO Chimassorb 944 (CAS 71878-19-8) kahi mea hoʻopaʻa māmā amine kaumaha kiʻekiʻe (HALS).
ʻO UV Absorber 944 kahi mea hoʻopaʻa māmā amine kiʻekiʻe-molecular-weight polymerized, e hōʻike ana i ka volatility haʻahaʻa, ke kū'ē i ka neʻe ʻana, a me ke kū'ē i ka mahana kiʻekiʻe. Hiki i nā hui amine i hoʻopaʻa ʻia i loko o ke ʻano kemika o UV 944 ke hopu pono i nā radical manuahi, no laila e pāʻani ana i kahi kuleana i ka hoʻopaʻa ʻana i ka mālamalama.
Hoʻopaʻa ka polymeric kiʻekiʻe-ka pono i ka amine light stabilizer, haʻahaʻa ka volatilization, haʻahaʻa ka neʻe ʻana, kūpaʻa wela a me ka hopena anti-oxidation, synergistic me nā antioxidants a me nā mea hoʻomoʻa UV. Hiki ke hoʻopili ʻia ʻo UV Absorber 944 i nā polyolefins, olefin copolymers, akā no nā polyphenylene ether complexes, polyoxymethylene, amides, PVC palupalu a paʻakikī a me nā hui PVC.

Hiki iā Chimassorb 944 ke hoʻoikaika pono i ke kūpaʻa o ka mālamalama o nā huahana lahilahi, ʻoiai nā huahana fiber a me nā kiʻiʻoniʻoni. He kūpono hoʻi ʻo UV 944 no nā huahana ʻāpana mānoanoa a me nā huahana polyethylene.
ʻO nā kahua noi o UV Absorber 944 e komo pū me nā polyolefin plastics (e like me PP, PE), nā olefin copolymers (e like me EVA), a me nā hui ʻana o ka polypropylene (PP) a me nā elastomers, a pēlā aku. Eia kekahi, hiki ke hoʻohana ʻia ʻo UV Absorber 944 i loko o ka polyoxymethylene (POM), polyamide (PA), polyurethane (PU), PVC palupalu a paʻa, a me nā hui PVC. He kūpono loa hoʻi ʻo Chimassorb 944 no nā noi kūikawā o nā elastomers a me nā mea hoʻopili i hoʻokumu ʻia i ka styrene.
✅He kūpaʻa maikaʻi loa ko Chimassorb 944 i ka mālamalama a hiki ke pale pono i ka hōʻino ʻana, ka hoʻololi ʻana o ke kala a me ka embrittlement o nā plastics i hoʻokumu ʻia e nā kukuna ultraviolet.
✅Loaʻa i ka UV Absorber 944 nā waiwai anti-extraction maikaʻi a ʻaʻole ia e neʻe aku mai nā plastics i ka wā hoʻohana lōʻihi.
✅He kūpono loa ka UV 944 a hiki ke hoʻopuehu like ʻia i loko o ke kino plastik me ka ʻole o ka hoʻopilikia ʻana i ka hana hana a me nā waiwai kino a me nā mechanical o ka plastik.
