I-tube yokunciphisa ubushushu bodonga olubini lwenziwe nge-polymer esemgangathweni ophezulu (umaleko wangaphandle) kunye ne-adhesive eshushu enyibilikayo (i-layer yangaphakathi) .I-tubing ye-heat shrink tubing ikhusela umswakama kunye neendawo ezinobungozi, ngelixa ubonelela ngokufakelwa kombane kunye nokukhuselwa komatshini. Ngexesha lofakelo, i-adhesive lining ye-industrial in the heat shrink tubing iyanyibilika kwaye isasazeke kwindawo enemigca idala umqobo okhuselayo, ongenamanzi. Xa iphola phantsi, umaleko wangaphakathi wenza umaleko wokubambelela phakathi kwetyhubhu kunye necandelo okanye ucingo. Ibonelela ngesitywina esiqinileyo samanzi kunye nokukhusela izihlanganisi okanye iingcingo.Ubushushu bokusebenza obuqhubekayo bufanelekile kuMinus 55°C ukuya kwi-125°C. Kukwakho nenqanaba lomkhosi elinomgangatho ophezulu wokusebenza we-135°C. Zombini i-3:1 kunye ne-4:1 umlinganiselo wokushwabana zilungile.
