3.2 Nā noi:
He mea koʻikoʻi ka CAS 50662-95-8 i nā ʻoihana like ʻole a me nā kahua noiʻi ma muli o kāna mau waiwai.ʻO kekahi mau polokalamu kaulana e komo pū me:
- Nā ʻāpana uila, e like me nā mea insulating a me nā papa kaapuni.
- Nā composites hana kiʻekiʻe, kahi e hoʻoikaika ai ka hui i ka ikaika mechanical a hoʻomaikaʻi i ke kūpaʻa wela.
- Thermoplastic resins, hāʻawi i ka pale wela a me ka paʻa kemika.
- Nā uhi a me nā mea hoʻopili, hoʻonui i ka lōʻihi a me ke kū'ēʻana i nā mea likeʻole.
3.3 Pono:
Ma ke koho ʻana i kā mākou pūhui CAS 50662-95-8 maikaʻi loa, hiki iā ʻoe ke manaʻo i kēia mau pōmaikaʻi:
- ʻO ke kūpaʻa wela maikaʻi loa, e hōʻoia ana i kāu huahana ke kū i nā wela kiʻekiʻe me ka ʻole o ka hōʻino.
- ʻOi aku ka ikaika mechanical, hoʻomaikaʻi i ka lōʻihi a me ka lōʻihi o nā mea.
- Kūleʻa kemika koʻikoʻi, pale i nā mea corrosive.
- Nā waiwai uila maikaʻi, hiki ke hoʻomohala i nā ʻāpana uila holomua.
- Nā noi maʻamau ma waena o nā ʻoihana like ʻole, e hāʻawi ana i nā hopena hou no kāu mau pono kikoʻī.
