Ko te tikanga, ko te pāmahana hanga kiriata o te paura rapa ka taea te whakamarara anō kei runga ake i te 0°C, ko ngā hua EVA ia he pāmahana hanga kiriata kei te 0–5°C. I ngā pāmahana iti iho, kāore e taea te hanga kiriata (he ngoikore rānei te kounga o te kiriata), ka whakararu i te ngāwari me te piri o te moata polymer. Hei tāpiri, ka puhoi te tere whakarewa o te cellulose ether i ngā pāmahana iti, ka pā ki te piri me te kaha mahi o te moata. Nō reira, me mahi te hanganga i runga ake i te 5°C i te mea ka taea kia pai ai te kounga o te kaupapa.
Ko te kaiāwhina kaha wawe he ranunga ka taea te whakapai ake i te kaha wawe o te moata me te kore e pā kino ki tōna kaha whakamutunga. E ai ki tōna hanganga matū, ka wehea ki ngā momo rauropi me ngā momo kore-rauropi: ko ngā kaiāwhina kaha wawe rauropi ko te konupūmā formate, te triethanolamine, te triisopropanolamine, te urea, me ētahi atu; ko ngā mea kore-rauropi ko ngā sulfates, te chlorides, me ētahi atu.

Me hiahia koe ki tētahi tāpiringa maha-whakamahinga hei whakanui ake i te pai o te whāngai, ME te whakateretere i te whakatakoto o te raima? Ka tukuna e tā mātou konupūmā formate tino-parakore ngā mea e rua – pāwhiri ki konei hei iriti i ngā otinga kua whakaritea mō tō umanga.
