EPDM (Ethylene- propylene-diene) ikozwe mu gipimo ca monomere ca éthylene pylene inyuma y’ugusenya no gusuzuma. Bafise ugushikama gukomeye kw’imiti n’ubushobozi bwiza cane bwo guhangana n’ikirere, kandi bikoreshwa cane mu bibanza vy’imikino, ibibanza vy’abana n’ibindi.
-Ivyuka bikomeye n’ugupfukama: imiterere y’ibinogo biri imbere mu bice bishobora gufata ingaruka z’ukwinyiganza (igipimo c’ugufata ibintu mu buryo burenze 50%), bigabanya ibikomere vyo kugwa, bibereye ku nzira yo kwiruka, ikibuga c’umupira w’amaguru n’ibindi bice vy’imikino.
-Ubushobozi bwo guhangana n’uburemere n’ugukura: bishobora kwihanganira- 40 ku +120 Itandukaniro ry’ubushuhe ry’urugero, ozone n’imvura, ubuzima bwo hanze bushika ku myaka 8-10.
- Umutekano w'ibidukikije: atari -
-Ibara riramvye: gutera ibara ry’umubiri, ibara ry’umubiri ryihuta ni ibiharuro birenga 8, igihe kirekire- Ijambo ridazimangana, amabara asanzwe ni ay’umutuku, icatsi kibisi, ubururu, ubururu, ubururu n’ibindi.
- Inyubakwa y’ibintu: ivanze n’ivyuma vy’ivyuma (nk’ivy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’Ivyuma, bishobora gukwiragira mu gice c’uburemere buringaniye, n’inkomezi z’ubufatanye zirenga 0.5MPa, kandi ntivyoroshe kugwa.

Ingingo nyamukuru zo guhingura no kwubaka ibiharuro vy'imikino y'ubuhinga bwa EPDM mu mashure
-Ivyiyumviro vy’ukuri: Igipimo c’ibikoresho vy’inyongera kiragira ico gikoze ku buryo butaziguye n’ubushobozi bwo guhangana n’ikirere, bikaba bisaba ingero nyayo.
-Igenzura ry’ubushuhe bwo guhindura ubushuhe: Ubushuhe budahagije burashobora gutuma ibihimba bimenagurika, mu gihe ubushuhe burenze urugero bushobora kwihutisha gukura.
-Ivyiyumviro vy’ubunini bw’ubunini: Uburyo bwo gusuzuma ni bwo bugena ukuntu ibice vyashizweko, bisaba ko igicapo gikomeza gupima.
Imisoro ishushe: igice c'umugwi w'imikino ya EPDM ku mashure, Ubushinwa ni igice c'umugwi w'imikino ya EPDM ku bahinga b'amashure, uruganda .
