He pauka keʻokeʻo kēia huahana me kahi kiko heheʻe o 160-175°C, kahi kiko lapalapa o 168°C, a me kahi kiko kuni o 421°C. He maʻalahi ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me toluene, methyl chloride, a me chloroform, hoʻoheheʻe iki ʻia i ka waiʻona, a ʻaʻole hoʻoheheʻe ʻia i ka wai. ʻO ka Antioxidant 626 he pauka keʻokeʻo a keʻokeʻo paha me ka haʻahaʻa haʻahaʻa a me ka pono kiʻekiʻe. Hoʻohana pinepine ʻia ia me ka hui pū ʻana me nā antioxidants phenol hindered.

1. Hoʻohana nui ʻia ka Antioxidant 626 i ka synthesis a me ka hana ʻana o nā ʻano plastics like ʻole e like me ka polypropylene, polyethylene, ABS, polycarbonate fiber a me ka polyester resin.
2. ʻO ka Antioxidant 626 kahi antioxidant kōkua phosphite me ka volatility haʻahaʻa, hiki ke pale pono i ka discoloration polymer, hoʻemi i ka nui o ka degradation polymer, a hoʻomaikaʻi i ke kūpaʻa o ka resin i ka mae ʻana o ke kinoea. He kūpono loa ia no nā polyolefins a me nā olefin copolymers, polycarbonate, polyamide a me nā plastics ʻenekinia ʻē aʻe, a me ka rubber, coatings a me nā adhesives. ʻO ka hoʻohui ʻana o ka antioxidant 626 hiki ke hoʻomaikaʻi nui i ke kūpaʻa hana o ka mea, a hoʻohana nui ʻia i ka hana ʻana o ka polyethylene, polypropylene, ethylene-vinyl acetate copolymer, polystyrene, polyvinyl chloride a me nā thermoplastics a me nā elastomers ʻē aʻe. waena. Eia kekahi, loaʻa i ka antioxidant 626 ka pale maikaʻi loa i ka discoloration i hoʻokumu ʻia e ka mālamalama a me ka wela, a me kahi hopena hoʻopaʻa kukui, hiki ke hoʻomaikaʻi i ka mālamalama, ke kūpaʻa wela, ka ikaika mechanical a me ke kūpaʻa kala o ka huahana, no laila e hoʻolōʻihi i ke ola o ka huahana.
3. Loaʻa i ka Antioxidant 626 nā waiwai kemika paʻa a me ka hoʻohālikelike maikaʻi me ka hapa nui o nā polymers. He antioxidant kōkua phosphite maikaʻi ia. ʻAʻole hiki i kona hoʻohana ʻana ke hoʻomaikaʻi wale i ke kūpaʻa hana o nā mea, akā hoʻomaikaʻi pū i ka mālamalama, ke kūpaʻa wela, ka ikaika mechanical a me ke kūpaʻa kala o nā huahana. He mea hoʻohui koʻikoʻi ia i hoʻohana nui ʻia i ka ʻoihana plastics.
