1. Polyethylene (PE)
Ho tsitsa ha lik'hemik'hale ho molemo, empa e tla ba oxidized le brittle ha e kopana le oxidant;Ha e qhibilihe ka har'a mokelikeli mochesong oa kamore, empa e tla ba bonolo kapa ea atoloha haeba ho na le solvent e senyang;Thepa ea bohloeki ke eona e ntle ka ho fetisisa.Mohlala, metsi a hloekisitsoeng a sebelisoang molemong oa setso hangata a bolokiloe ka libotlolong tsa polyethylene.
2. Polypropylene (PP)
E ts'oana le PE ka sebopeho le ts'ebetso ea bohloeki, e tšoeu ebile ha e latsoehe, e na le letsoalo le lenyenyane, 'me ke eona e bobebe ho fetisisa har'a lipolasetiki.E hanyetsana le khatello e phahameng, e qhibilihang mocheso oa kamore, ha e sebetse le mecha ea litaba e mengata, empa e na le maikutlo a matla ho li-oxidants tse matla ho feta PE, ha e hanyetsane le mocheso o tlaase, 'me e senyeha habonolo ho 0 ℃.
3. Polymethylpentene (PMP)
E pepenene, e hanyetsa mocheso o phahameng (150 ℃, 175 ℃ ka nako e khutšoanyane);Khanyetso ea lik'hemik'hale e haufi le ea PP, e nolofalitsoeng habonolo ke li-solvents tse nang le chlorinated le hydrocarbons, 'me e bonolo ho feta PP;Boima bo phahameng, brittleness e phahameng le fragility mocheso oa kamore.
4. Polycarbonate (PC)
E pepenene, e thata, ha e na chefo, khatello e phahameng le ho hanyetsa oli.E ka sebetsana le joala ba alkali le asiti e ngata ea sulfuric, ea hydrolyze 'me ea qhibiliha ka har'a metsoako e fapaneng ea tlhaho ka mor'a ho futhumatsoa.E ka sebelisoa e le tube ea centrifuge ho thibela ts'ebetso eohle ka lebokoseng la ultraviolet sterilization.
5. Polystyrene (PS)
Ha e na 'mala, ha e na tatso, ha e chefo, e pepenene ebile ea tlhaho.Ho hanyetsa ha solvent ho fokola, matla a tlase a mochini, brittle, ho peperana ho bonolo, ho hanyetsa mocheso, ho cha.Hangata e sebelisoa ho etsa lisebelisoa tsa bongaka tse lahloang.
6. Polytetrafluoroethylene (PTEE)
E tšoeu, e opaque, e sa sebetse, hangata e sebelisetsoa ho etsa li-plug tse fapaneng.
7. Polyethylene terephthalate G copolymer (PETG)
E bonaletsang, e thata, e sa keneleng moea, 'me ha e na chefo ea baktheria, e sebelisoa haholo moetlong oa lisele, joalo ka ho etsa libotlolo tsa setso sa lisele;Lik'hemik'hale tsa radiochemical li ka sebelisoa bakeng sa ho bolaea likokoana-hloko, empa ho thibela likokoana-hloko ka khatello e phahameng ho ke ke ha sebelisoa.
