Māmā Māmā-944 CAS 70624-18-9
ʻO ka UV-944 stabilizer māmā he kūpaʻa maikaʻi loa, kūpono loa no nā huahana lahilahi, e like me nā fibers a me nā kiʻiʻoniʻoni; Hiki iā ia ke hoʻomaikaʻi i ke kūpaʻa ʻana o ka oxygen thermal o ka mea. ʻO ka stabilizer māmā HS-944 keʻokeʻo i nā'āpana melemele māmā a iʻole ka pauka, ka helu hoʻoheheʻe 100-135 ° C, ke kaumaha mole 2000-3100, me ka hoʻohālikelike maikaʻi loa, ke kū'ēʻana a me ka haʻahaʻa haʻahaʻa. No ka mea ʻo UV-944 he mea hoʻokūpaʻa kiʻekiʻe molecular mass stabilizer, a he nui wale ka methylate i loko o ka mole, paʻa ia ke mālama ʻia me ka oxygen wela.
