ʻO ka ʻike ʻepekema kaulana：
He maikaʻi loa ka ʻōpala kūlohelohe i ke kino a me ka mechanical, maikaʻi ka elasticity o ka lāʻau kūlohelohe i ka lumi wela, no ka mea he amorphous ke kaulahao molekala maoli i ka lumi wela, maikaʻi ke kaulahao molecular flexibility.Thermal elemakule kūlohelohe kino he kiʻekiʻe elastic kino i ka lumi wela, vitrification wela -72 degere, lohi mālie ma hope o ka hoʻomehana ʻana, hoʻomaka e kahe ma 130-140 degere, ma kahi o 200 decompose i hoʻomaka e decompose, 270 decomposition ikaika.
ʻO ka hana hana maikaʻi, ka lāʻau kūlohelohe ma muli o ke kaumaha molecular pili kiʻekiʻe, ka pālahalaha ākea o ka paona molekala, ua maʻalahi ke kaulahao molekala, i hui pū ʻia me kahi helu o nā molekala gel i loko o ka ʻōpala maka, no laila ua maʻalahi ka plasticizing, hui ʻana, calendering, kaomi, hoʻoheheʻe a pēlā aku.
