Njengoba isidingo sezinto ezinamathelayo ze-polypropylene ezisebenza kahle nezithembekile sikhula, imboni izofakaza ngezinto zokwakha, ukwakheka, nezindlela zokufaka izicelo. Ngocwaningo oluqhubekayo nentuthuko, abakhiqizi kungenzeka babhekane nezinselelo ezihambisana nokubopha i-polypropylene futhi basunduze imingcele yobuchwepheshe bokunamathela, okuholela ekusebenzeni okuthuthukisiwe, ukusimama okukhulayo, kanye nokukhiqiza okuthuthukisiwe esikhathini esizayo.

Isiphetho

Izinto ezinamathelayo ze-polypropylene ziguqule indlela esijoyina ngayo i-polypropylene namanye ama-substrates ezimboni ezihlukahlukene, okuhlanganisa ezezimoto, izimpahla zabathengi, ezokwelashwa, ze-electronics, ezokwakha, i-aerospace, nezasolwandle. Izinhlobo ezahlukene zokunamathiswa kwe-polypropylene bonding zinikeza uhla lwezinzuzo, okuhlanganisa amandla ebhondi aphezulu, izinga lokushisa kanye nokumelana namakhemikhali, ukusetshenziswa okulula nokususwa, kanye nezindleko eziphansi. Ukukhetha i-adhesive efanelekile ye-substrate kanye nesicelo kuqinisekisa isibopho esithembekile nesihlala isikhathi eside. Njengoba imizamo yocwaningo nentuthuko iqhubeka, singalindela ngisho nezinamatheliso eziningi ezintsha ze-polypropylene ezinikeza ukusebenza okuphezulu, ukusimama, kanye nokuguquguquka. Izinamatheliso ezihlanganisa i-polypropylene zisethelwe ukuthi zidlale indima ebaluleke kakhulu ekukhiqizeni nasembonini, okusenza sikwazi ukujoyina izinto ezihlukahlukene ngempumelelo nangempumelelo.
