I-EPP isetshenziswa kabanzi kuloliwe ohamba ngesivinini esiphezulu, izimoto kanye neminye imikhiqizo yezimboni, njenge-bumper core material, i-anti-collision block, uphahla nezinye izingxenye ze-lining, ukugcwaliswa kweminyango, i-headrest, i-sunshade nokunye, okungasindisa ukusetshenziswa kukaphethiloli futhi kuthuthukiswe. isici sokuphepha kwabagibeli.

I-EPP isetshenziswe kabanzi embonini yokupakisha, njengemikhiqizo ye-elekthronikhi, izinsiza zezokwelapha, njll., ikakhulukazi ekufakweni kwemikhiqizo ethunyelwa ngaphandle, isiphenduke iphakheji engenakushintshwa ukuze ihlangabezane nezidingo zokuvikelwa kwemvelo.Ngenxa yokumelana kwayo nokushisa okungeyona ubuthi kanye nokushisa okuphezulu, ibuye isetshenziswe kakhulu ekufakweni kokudla kanye nokushisisa i-microwave.

Ekugcineni, i-EPP yenziwe nge-polypropylene yamandla aphezulu aphezulu (HMSPP) kune-polypropylene evamile (PP).

Amangqamuzana ajwayelekile e-PP alula (akuyona imfoloko) kufanele adlule ekucutshungulweni okuthile, ukuze ama-molecule awo abe imfoloko, eyaziwa ngokuthi yi-PP graft (ukuwohloka kwe-graft okujwayelekile kuzokwenzeka, hhayi ukulenza libe ne-viscosity ephezulu kanye nenhloso yamandla ancibilikayo aphezulu. ).Ngokuvamile, ubuhlalu be-EPP kufanele bulayishwe ethangini lokucindezela kuqala (ngisho noma ubuhlalu bugcwele ukucindezela okuthile komoya), bese bujovwa esibunjeni somshini wokubumba we-EPP onomoya ocindezelwe ngesibhamu sokufutha, ngesitimu ukuze ngokuqhubekayo wandise ubuhlalu be-EPP kanye nokuhlangana kwendawo ndawonye nokwenza.Ngemuva kokupholisa, isikhunta siyazinza ekushiseni okuthile ukuze kutholwe imikhiqizo ye-EPP.
