ʻO PIR kahi waihona e hoʻohui i nā kumuwaiwai lehulehu o ka ʻikepili wānana hana protein, e manaʻo ana e kākoʻo i ka noiʻi genomics/proteomics. Hana pū ʻo PIR me nā hui ʻē aʻe e hoʻokumu i ka PIR International Protein Sequence Database (PSD)-kahi waihona nui o nā protein i wānana ʻia, me 250,000 proteins. Hana PIR
ʻO ka PIR kahi mea hoʻokalakupua polymer organik hou, he polymer foam i hana ʻia e ka hui piha ʻana, reacting, a me ka hoʻoulu ʻana i ka isocyanate a me ka polyether ma ke ʻano he kumu kumu, me nā catalysts, fire retardants, a me nā mea hoʻoulu ʻana i ke kaiapuni, ma lalo o ka hoʻolālā kūikawā a me nā kūlana kaʻina hana koʻikoʻi. Ma muli o kona hale paʻa kūʻokoʻa -a me ka lākiō kiʻekiʻe i pani ʻia, ua loaʻa i ka polimer foam nā pūnaewele maikaʻi a ʻano like ʻole, maikaʻi ka hana ʻana i ka wela wela, a ʻoi aku ka maikaʻi o nā waiwai pale ahi, no laila e hōʻike ana i nā ʻano maikaʻi loa ma ke ʻano o ka insulation wela, ka wai permeability, adhesion, ikaika compressive, retardancy lapalapa, a me ke anuanu. ʻO kēia -ʻenehana polymer ʻenehana kiʻekiʻe ka mea e hoʻolalelale ai i ke ahi maikaʻi loa, haʻahaʻa haʻahaʻa haʻahaʻa, kūpaʻa wai maikaʻi, kūpaʻa nā waiwai kemika, a me ke kūpaʻa ʻelemakule maikaʻi, e lilo ia i mea koho maikaʻi loa no nā polymers insulation thermal i loko o ka cryogenic a me ka hoʻoilo maʻamau. ʻO ka laulā wela o ka hoʻopulapula kūpono ʻo -196 degere a i +120 degere.
ʻO ka polyisocyanate foam (PIR), ma ke ʻano he mea hou anu a me ka wela wela ma ka honua, ua ʻike mua i ka noi ākea i nā ʻāina ʻEulopa i kūkulu ʻia i nā kula e like me ka ʻenekinia ikehu petrochemical, ke kūkulu ʻana, a me ka pale ʻana i ke kaiapuni a me ka mālama ʻana i ka ikehu. Ma koʻu ʻāina, aia nō ʻo PIR i ka hoʻomaka ʻana o ka hoʻomohala ʻana, me nā noi i kaupalena ʻia i nā ʻāpana kinoea a me nā petrochemical e like me LNG (-165 degere, liquefied natural gas) a me ka wai ethylene (-104 degere).
