Kufuma pakwamba kwa raba, ŵa ku Manjiliro gha dazi ŵalutilira kupanga kugwiriskira ncito . Germany Frederick wakapanga maboti ghakukwera na labala ghakusungunuka mu ether . Rubber wangawuskapo vimanyikwiro vya pensulo, ntheura ŵanthu ŵakupanga mu labala. Kweni labala lili na kupuvya kwakukoma, ilo likukhwaskika chomene na kutentha. Para kutentha kuli pachanya pachoko, kuzamuŵa kwakufewa na kwakumatira, ndipo kuzamuŵa kwakununkhira kunangika; para kutentha kwakucepa, kuzamuŵa kwakuphwanyika ndiposo kwakukhora . Kusoŵa uku kukupangiska kuti vinthu vya labala viŵevya msika .
Mu chilimwe cha 1834, Goodyear wakaluta ku kampani ya Indian Rubber ya Indian Rubber . Wakamanya kuti mtundu uwu wa labala ukasuzganga mafakitale ghose gha labala, kweni labala wali na vinthu vinandi viwemi nga ni elasticity yikuru, pulasitiki, kukhalilira, kukhalilira, kutondeka maji na insulation{{{{{ {{ {{ {) Viyelezgero wakusimikizga kusambira kusintha kwa labala .
Goodyear ni kemiko yayi panji wasayansi. Mu fakitare, wakugwira ntchito nga ni wantchito, nyengo zose wakuŵika vinthu vyakupambanapambana kuti wayezge na labala .

Vinthu ivi vikuvunda yayi pa nyengo yakutentha chomene kuluska labala wa elastic ristal . Pamanyuma pa mndandanda wa kusintha, Goodyear wakakhorwa kuti vinthu ivyo wakanozga vikuvunda yayi pa nyengo yiliyose iyo yili pasi pa malo ghakuwira, ndipo luso la raba vulcanization likababika {{ ndimu}}
