Hari ubwoko bwinshi butandukanye bw'amakoti y'insinga kandi buri koti ikora neza mu buryo bwihariye. Amakoti atatu y'ingenzi y'insinga z'icyuma ni PVC (Polyvinyl Chloride), PUR (polyurethane) na TPE (thermoplastic elastomer). Buri bwoko bw'ikoti bufite ibyiza bitandukanye nko gukaraba, kwirinda kwangirika cyangwa gukonja cyane. Kubona ubwoko bw'ikoti bukwiye bwo gukoresha bishobora kongera igihe cy'insinga.
PVCni insinga ikoreshwa muri rusange kandi iraboneka henshi. Ni insinga isanzwe, kandi akenshi ifite igiciro cyiza. PVC ifite ubushobozi bwo kwirinda ubushuhe bwinshi, bigatuma iba amahitamo meza yo kuyikoresha mu gusukura.
PURiboneka cyane cyane muri Aziya no mu Burayi. Ubwoko bw'ikoti ry'insinga bufite ubushobozi bwo kurwanya kwangirika, amavuta na ozone. PUR izwiho kuba idafite Halogen, ntabwo irimo: chlorine, iyode, fluorine, bromine cyangwa astatine. Ubwo bwoko bw'ikoti bufite ubushyuhe buke ugereranije n'ubundi bwoko bw'ikoti, -40…80⁰C.
TPEIraryoha, ishobora kongera gukoreshwa kandi ifite ubushyuhe bwiza cyane, -50…125⁰C. Iyi nsinga irarwanya gusaza mu zuba, UV na ozone. TPE ifite amanota yoroshye cyane, ubusanzwe miliyoni 10.
Imbonerahamwe iri hepfo isobanura uburyo umupira udashobora guhangana n’ibihe bitandukanye. Menya ko ibi bipimo bishingiye ku musaruro mpuzandengo. Gushyiramo ikoti mu buryo bwihariye bishobora kunoza imikorere.
