ʻO Antixoidant 245 kahi ʻano o ka antioxidant phenolic asymmetric kiʻekiʻe, a ʻo kāna mau hiʻohiʻona kūikawā e pili ana i ka antioxidation kiʻekiʻe, haʻahaʻa volatility, kūʻē i ka kala ʻana, ka hopena synergistic koʻikoʻi me ke kōkua antioxidant (e like me ka monothioester a me ka phosphite ester), a me ka hāʻawi ʻana i nā huahana i ka weathering maikaʻi. kū'ē ke hoʻohana ʻia me nā stabilizer māmā. Hoʻohana nui ʻia ʻo Antioxidant 245 e like me ke kaʻina hana a me ka stabilizer lōʻihi no ka styrene polymer e like me HIPS, ABS, MBS, a me nā thermoplastics ʻenekinia e like me POM a me PA, ʻoiai ʻo ia ka mea hoʻopau hope o ke kaulahao i ka polymerization PVC. Eia kekahi, ʻaʻohe hopena o ka huahana i nā hopena polymer. Ke hoʻohana ʻia no HIPS a me PVC, hiki ke hoʻohui ʻia i nā monomers ma mua o ka polymerization.
