Isangqa seplastikhi sekhephu senziwe ngeplastikhi enganyangekiyo ngobushushu kunye neekhemikhali, kubandakanya i-polyethylene (PE), i-polypropylene (PP), i-polypropylene eqinisiweyo (RPP), i-polyvinyl chloride (PVC), i-polyvinyl chloride (CPVC) kunye ne-polyvinylidene fluoride (PVDF). Inezinto ezinje ngevolumu ephezulu yasimahla, ukwehla koxinzelelo olusezantsi, ukuphakama kweyunithi yokuhambisa ubuninzi, indawo ephezulu yezikhukula, unxibelelwano olufanayo lwegesi-ulwelo, amandla amxhuzulane amancinci, ukusebenza ngokugqibeleleyo kobunzima nokunye, kunye nobushushu besicelo kumanqanaba eendaba ukusuka 60 ukuya ku-150. Ngezi zizathu isetyenziswa ngokubanzi kwiinqaba zokupakisha kwimveliso yepetroleum, ishishini leekhemikhali, ishishini lealkali-Chloride, ishishini legesi yamalahle kunye nokukhuselwa kwendalo, njl.
