HANGANGA:
Ko te Maleic Anhydride (MAN) he pūhui waro kei roto ko te tātai matū C4H203. Ko te waikawa anhydride o te waikawa maleic, ā, i tōna āhua parakore he totoka kore tae, he mā rānei, he kakara kawa. He ngota tino whakamiharo te maleic anhydride nā te mea e rua ngā momo mahi matū kei a ia, ā, he tino whai hua i roto i te hanga matū me ngā tono.
He matū maha-mahi te Maleic Anhydride, ā, he maha ngā whakamahinga i roto i ngā mara maha o te umanga matū. Ko tōna whakamahinga matua ko te hanga rauemi mō te hanga kapia polyester kāore i te mākū (UPR).
E whakamahia ana ēnei kapia i roto i ngā mahi whakakaha karāhe me ngā mahi kāore i whakakaha. Kei roto i ngā whakamahinga mutunga o te UPR he whānuitanga o ngā mahi i roto i te hanga whare, te moana me te motuka.
