Icoke yepetroleum eyotyiweyo (PET Coke)yimveliso yepetroleum coke eye yabalwa kumaqondo obushushu aphezulu. Isetyenziselwa ukwenza igraphite, ishishini lokunyibilikisa, ishishini lemichiza, kunye neshishini lemathiriyeli yefriction.

Kwimathiriyeli yokukhuhlana, i-coke yepetroleum ene-calcined (PET Coke)idlala indima ebalulekileyo. Ekubeni i-PET coke ineempawu zobunzima obuphantsi kunye ne-porosity ephezulu, idlala indima enkulu ekunciphiseni ubulukhuni bemveliso, ukunciphisa ingxolo ye-braking kunye nokunciphisa ukubola kwe-thermal ye-friction materials kumaqondo aphezulu okushisa kwi-braking materials.

Singabonelela ngemveliso yenqanaba elahlukileyo, sikwavuyiswa ukubonelela ngemveliso elungiselelwe abathengi bethu abakhulu abavela kwihlabathi liphela.
