Mmetụta nke vulcanization na nhazi na akụrụngwa:
Na usoro mmepụta nke ngwaahịa roba, vulcanization bụ usoro nhazi ikpeazụ.N'ime usoro a, roba na-enweta usoro mmeghachi omume kemịkalụ dị mgbagwoju anya, na-agbanwe site na nhazi usoro gaa n'ụdị ahụ, na-efunahụ plasticity nke rọba agwakọta ma nwee nnukwu ngbanwe nke roba jikọtara ọnụ, si otú ahụ na-enweta ọmarịcha anụ ahụ na ígwè ọrụ.
