He pai te ngāwari o ngā papanga i hangaia mai i te muka polyester, he ātete ki ngā kita, he mau tonu te āhua, he pai te mahi horoi me te mau, ā, he maha atu anō hoki ngā āhuatanga e whakamahia whānuitia ana i roto i ngā momo papanga kākahu katoa.
Ka hangaia mā te tauhohenga o te waikawa dicarboxylic ki te waipiro dihydric. Ka taea te whakamahi i tēnei rauemi turanga hei hanga i ngā mea maha, mai i ngā pounamu houra ki ngā poti, tae atu ki ngā muka kakahu. Pērā i te nairona, ka mirohia te polyester – mā tēnei tukanga ka taea te hanga i ngā muka i roto i ngā āhua me ngā rahi rerekē mō ngā tono motuhake.
