Ka puta te wera i te waea whakamahana ina whakamahia te ngaohiko kua whakatauria ki ngā pito e rua, ā, ka pumau tōna pāmahana i roto i te awhe i raro i te pānga o ngā āhuatanga whakamarara wera ā-taha. Ka whakamahia hei hanga i ngā momo āhua whakamahana hiko e kitea whānuitia ana i roto i ngā hauhautanga, ngā pouaka whakamātao, ngā pouaka tio, ngā ipu wai, ngā oumu raihi, me ētahi atu taputapu kāinga.
E ai ki te rauemi whakamahana, ka taea te whakamahi i te waea whakamahana ātete-PS, te waea whakamahana PVC, te waea whakamahana rapa silicone, me ētahi atu. E ai ki te rohe mana, ka taea te wehewehe ki ngā momo waea whakamahana e rua: te mana kotahi me te mana maha.
Ko te waea whakamahana ātete-PS he momo waea whakamahana e tino pai ana mō ngā āhuatanga e hiahiatia ana te pā tika ki te kai. Nā te mea he iti tōna ātete wera, ka taea anake te whakamahi i ngā āhuatanga iti te mana, ā, he roa te awhe pāmahana mahi mai i te -25 °C ki te 60 °C.
He waea whakamahana whānuitia te waea whakamahana 105°C, ko te kaha toharite kāore e neke ake i te 12W/m, ā, ko te pāmahana whakamahi mai i te -25°C ki te 70°C. Kua hipokina ki ngā rauemi e tutuki ana i ngā whakaritenga o te paerewa PVC/E i roto i te GB5023 (IEC227), me te ātete wera pai rawa atu. Hei waea whakamahana ātete-hau, he whānuitia te whakamahinga i roto i ngā pouaka whakamatao, ngā hauhautanga, me ētahi atu.
Nā tōna ātete wera tino pai, he maha ngā whakamahinga o te waea whakamahana rapa silicone ki ngā mīhini whakarewa hukapapa mō ngā pouaka whakamātao, ngā pouaka tio, me ētahi atu taputapu. Ko te pāmahana whakamahinga kei waenga i te -60°C ki te 155°C, ā, ko te matotoru o te mana he tata ki te 40W/m. I ngā taiao pāmahana iti me te pai o te tohatoha wera, ka taea e te matotoru o te mana te eke ki te 50W/m.
