I. Ivyo bisa n'ivyo :
Naho ari ibikoresho bibiri bitandukanye, birasa n’ivyo mu buryo bwa macroscope n’ibintu bimwebimwe vy’ishimikiro:
Ivyo bihimba vy’umubiri: Ivyo vyose bikorwa biciye mu nzira z’ifu canke z’imiti kandi vyuzuyemwo utugingo ngengabuzima tungana canke tudaringaniye imbere, ivyo bikaba bituma vyose biba ibiremereye, gushoberwa- no gushuha - gutera intege.
Elasitity: Nk’imibiri ikomeye, vyose birashobora gusubira ku rugero runaka no gusubira ku rwego rwavyo rw’intango inyuma y’aho bipfutse.
Ivyiza: Vyose bishobora gukorwa biciye mu gukanda bishushe biciye mu bikoresho kugira ngo bivemwo ibintu bitandukanye bikomeye- ibintu bifise ishusho, nk’ibipfukisho, inkweto, inkweto zo hasi, n’ibindi.
Ivyo bikoresho vyose bifise ubushobozi bwo gukingira umuyagankuba n’ubushobozi bwo guhangana n’amazi.
II. Ubutandukane:
1. Ibikoresho n’Igiciro: EVA ni ikintu kiva kuri peteroli. Ibikoresho vyayo vya mbere biraboneka cane kandi uburyo bwavyo bwo gukora (nk’imwe - igihe n’ugushigikirwa na kabiri) ni ikintu gikomeye. Ku bw’ivyo, igiciro cayo ni gito cane kandi kirabereye ku bikoresho vy’abaguzi benshi. Silica gel ni igicuruzwa c'imbere mu gihugu c'ivyuma bita silikoni. Its raw materials and preparation processes (such as platinum catalytic foaming) are complex and the cost is extremely high.
2. Ubudahangarwa bw’ubushuhe n’ugusubiramwo urubeya (itandukaniro rikomeye cane) EVA ni ikintu c’ubushuhe. Igihe umuntu ashikiwe n’ubushuhe bwinshi (nk’uko birenga 70-80℃), bizokworosha, gufunguka, mbere no guturika no gutonyanga, gutyo bikaba bidafise urubeya. Iyi ni yo mpamvu nyamukuru ituma idashobora kwigera ikoreshwa mu bidukikije bifise ubushuhe bwinshi. Silicone ni ikintu gitera ubushuhe gifise ubushobozi bwo guhangana n’ubushuhe bwinshi cane n’ubushuhe buke. Ishobora gukora igihe kirekire ku 250℃kandi ishobora kwihanganira ubushuhe buri hejuru ya 300℃mu kiringo gito. Muri ico gihe nyene, ifise urugero runini rwo gusubira inyuma (gushika ku rugero rwa UL94 V-0), irazima ubwo nyene iyo ikuwe mw’isoko ry’umuriro, ntitanga amatonyanga y’umuriro, kandi afise umutekano mwinshi cane.
3. Ugukundana n’ibidukikije n’umutekano: Uburyo bwa EVA buratandukanye cane. High- uburyo EVA ishobora kuba idafise umunuko, ariko hasi- Ubusumbasumbane bushobora gukoresha ibikoresho vyasubiwemwo n’ibikoresho vyo hasi, bikaba bituma haba akamoto k’impeshi n’ibintu bishobora gutera ingorane (nk’imiterere). Silicone ni - ubumara kandi nta n’akamoto, ifise imiterere y’imiti idahinduka cane kandi ntizosohora ibintu bishobora gutera ingorane. Ishobora gutanga icemezo gikomeye cane nk’Ivyiyumviro vya FDA (Itangazo n’Imiti vya Leta Zunze Ubumwe za Amerika) na LFGB (Ivyigwa vy’Ivyokurya vy’Ubumwe bw’Uburayi), kandi bikoreshwa cane mu bikorwa vy’ubuvuzi n’ivy’ibifungurwa.
4. Ubushobozi n’ugutsinda Igitero kimwe gikomeye ca EVA ni igice kinini cane c’ugukomera. Mu mvugo yoroshe, EVA insole izoca ipfukwa inyuma yo kwambarwa igihe kirekire, idashobora gusubira ku buremere bwayo bw’intango no gutakaza uburemere bwayo. Agaciro k’ugufatanya ka silikoni ni gake cane, ivyo bikaba bisobanura ko bishobora gushika hafi rwose ku buryo bwawo c’intango inyuma y’aho bipfutse igihe kirekire. Ubuzima bwaco bwo gukora n’ubuzima bwaco burarengeye kure cane ubw’i EVA.
