Chotsatira

Ndiyeno izo zinachitika; zinthu zolimba koma anakhalabe kusinthasintha. Chomwe chimatchedwa vulcanization chinapanga chithumwa chochuluka, chinthu chokhazikika komanso chotheka.

Komabe, vulcanization yake idatengedwa ndi woyambitsa waku Britain Thomas Hancock pomwe adapeza zitsanzo zomwe zidabweretsedwa ku England ndi Goodyear.. Hancock adatumikira mowolowa manja 8 mapulogalamu a patent milungu ingapo kuposa a Goodyear. Izi pambuyo pake zidatsutsidwa ndi Goodyear.
