UV absorber-928 CAS 73936-91-1
ʻO ka UV absorbers 928 ka laulā o nā hiʻohiʻona absorption a hiki ke pale pono i nā pale a me nā mea photosensitive ʻē aʻe; ʻO ka solubility kiʻekiʻe, ke kūpaʻa wela kiʻekiʻe, a me ka lōʻihi o ke kaiapuni; He kūpono no nā ʻāpana hana kiʻekiʻe, ʻoi aku ka maikaʻi no nā uhi pauka a me nā uhi coil mau

Hoʻohana nui ʻia nā UV absorbers 928 e like me nā stabilizers māmā no nā plastics, rubber, coatings, dyes, etc., e pale i kā lākou photodegradation ma lalo o ka lōʻihi o ka ʻike ʻana i ka lā. Hiki ke hoʻohana ʻia no nā uhi kaʻa a me nā uhi maʻamau. ʻO ka maʻamau, ʻoi aku ka maikaʻi ke hoʻohana pū ʻia me nā stabilizer māmā UV-292 a i ʻole UV-123
Hoʻopili pinepine ʻia i ka 25kg / pahu, a hiki ke hana ʻia i ka pōʻai maʻamau.
