Polybutene CAS 9003-28-5
He kūpaʻa maikaʻi ko Polybutylene i ka wela. Kū i ka pala kemika i loko o nā aila, nā detergents a me nā solvents ʻē aʻe, ʻaʻole ia e hana i ka embrittlement e like me nā plastics ʻē aʻe e like me HDPE. Hana wale ʻia ka embrittlement ma lalo o nā oxidants ikaika e like me 98% sulfuric acid i hoʻohuihui ʻia. Kūʻē kolo maikaʻi loa. Loaʻa iā ia ke kūpaʻa ʻaʻahu like me ka polyethylene molecular kiʻekiʻe loa. ʻO Polybutene kahi polymer inert polymer, i hana nui ʻia mai ka polymerization o butene, he homopolymer polymer. Ke hoʻohālikelike ʻia me nā polyolefins ʻē aʻe, he paʻa ia. Ikaika tensile kiʻekiʻe.
| Mea | Nā kikoʻī |
| Kiko heheʻe | 104°C |
| Ka nui o ka paʻa | 0.91 g/mL ma 25 °C (mālamalama ʻia) |
| Palapala | ka ʻano palaoa |
Hoʻohana pinepine ʻia ʻo Polybutylene ma ke ʻano he plasticizer, mea hoʻopaʻa, mea hoʻohui kemika no nā mea hoʻohui gasoline, a me ka mea sila. ʻOiai ua ʻike ʻia ka polybutylene e hoʻomaikaʻi i nā waiwai e like me ka hoʻopili ʻana, ka pale ʻana i ka popo a me ke kūpaʻa wai i nā pena, hoʻohana pinepine ʻia ia i ka hana ʻana o nā mea hoʻonani e like me nā lipsticks.
Hoʻopili pinepine ʻia i loko o 200kg/pahu, a hiki ke hana ʻia kahi pūʻolo i hoʻopilikino ʻia.
