1. Selelekela
Polystyrene (PS) ke polymer ea thermoplastic e feto-fetohang le e theko e tlaase e sebelisoang haholo ho paketeng, thepa ea bareki le kaho. E fumaneha ka mefuta e 'meli ea mantlha—Polystyrene ea Morero o Akaretsang (GPPS, e hlakileng ka kristale) le Polystyrene e nang le tšusumetso e phahameng (HIPS, e tiisitsoeng ka rabara)—PS e nkoa e le ea bohlokoa ka lebaka la ho tiea ha eona, bonolo ba ho e sebetsana le eona, le theko e tlase. Sengoloa sena se hlahloba thepa ea polasetiki ea PS, lits'ebetso tsa bohlokoa, mekhoa ea ho e sebetsana le eona, le pono ea 'maraka.
2. Thepa ea Polystyrene (PS)
PS e fana ka litšobotsi tse fapaneng ho latela mofuta oa eona:
A. Polestyrene ea Morero o Akaretsang (GPPS)
- Ho Hlaka ha Optical – Ponahalo e bonaletsang, e kang ya khalase.
- Ho tiea le ho ba bonolo – Ho thata empa ho ka petsoha tlas'a khatello.
- E bobebe – Botenya bo tlase (~1.04–1.06 g/cm³).
- Ho thibela motlakase - Ho sebelisoa linthong tsa elektroniki le linthong tse lahloang.
- Khanyetso ea Lik'hemik'hale - E hanela metsi, li-acid le li-alkali empa e qhibiliha ka har'a li-solvents tse kang acetone.
B. Polystyrene e nang le tšusumetso e phahameng (HIPS)
- Ho Tiea ho Ntlafetseng – E na le rabara ea polybutadiene ea 5–10% bakeng sa ho hanyetsa ho tetebela.
- Ponahalo e sa bonahaleng – E bonahala hanyane ho feta GPPS.
- Ho Thermoforming ho Bonolo – E loketse ho paka lijo le lijana tse lahloang.
3. Litšebeliso tsa Bohlokoa tsa PS Plastic
A. Indasteri ea ho Paka
- Lijana tsa Lijo (Likopi tse lahloang, likhetla tsa clam, lisebelisoa tsa ho jela)
- Likhese tsa CD le DVD
- Foam e Sireletsang (EPS - Expanded Polystyrene) – E sebediswa ho paka dipeanut le ho kenya mochesong.
B. Thepa ea Bareki
- Lintho tsa ho bapala le tsa ho ngola (litene tse kang tsa LEGO, mabokose a lipene)
- Lijana tsa litlolo (Likhechana tse nyane, liphaephe tsa lipstick)
C. Lisebelisoa tsa Elektroniki le Lisebelisoa
- Li-Liner tsa sehatsetsing
- Likoahelo tsa Pontšo e Bonaletsang (GPPS)
D. Kaho le ho Thibela ho Kena ha Mocheso
- Liboto tsa Foam tsa EPS (Sesebelisoa sa ho kenya mocheso ka har'a moaho, konkreite e bobebe)
- Mekhabiso e Khabisitsoeng
4. Mekhoa ea ho Sebetsa bakeng sa PS Plastiki
PS e ka etsoa ka mekhoa e 'maloa:
- Ho Enta ka Ente (E Tloaelehileng bakeng sa lihlahisoa tse thata joalo ka lisebelisoa tsa ho betla)
- Ho ntša (Bakeng sa maqephe, lifilimi le liprofaele)
- Thermoforming (E sebelisoa liphuthelong tsa lijo)
- Ho Bopa Foam (EPS) – PS e atolositsoeng bakeng sa ho kenya mocheso le ho sireletsa letlalo.
5. Mekhoa le Liphephetso tsa 'Maraka (Pono ea 2025)
A. Tšireletso le Likhatello tsa Taolo
- Lithibelo tsa PS e Sebediswang Hanngoe – Dinaha tse ngata di thibela dihlahiswa tsa PS tse lahlwang (mohlala, Taelo ya EU ya Plastics e Sebediswang Hanngwe).
- PS e Sebedisitsweng Botjha le e Thehilweng ho Bio – Tlhoko e ntseng e hola ya mekgwa e meng e sireletsang tikoloho.
B. Tlholisano ho tsoa ho Lipolasitiki tse Ling
- Polypropylene (PP) – E hanela mocheso le ho tšoarella bakeng sa ho paka lijo.
- PET & PLA – E sebelisoa ka har'a liphutheloana tse ka sebelisoang hape/tse bolang.
C. Matla a 'Maraka oa Libaka
- Asia-Pacific (Chaena, India) e laola tlhahiso le tšebeliso ea PS.
- Amerika Leboea le Yuropa li shebane le ho sebelisa hape le ho kenya lintho ka har'a EPS.
- Bochabela bo Hare bo tsetela tlhahisong ea PS ka lebaka la litšenyehelo tse tlase tsa lijo.
6. Qetello
Polystyrene e ntse e le polasetiki ea bohlokoa ho paketeng le thepa ea bareki ka lebaka la litšenyehelo tsa eona tse tlase le bonolo ba ho e sebetsana. Leha ho le joalo, matšoenyeho a tikoloho le lithibelo tsa taolo ho PS e sebelisoang hanngoe li khanna boqapi ba ho sebelisa hape le mekhoa e meng e thehiloeng linthong tse phelang. Bahlahisi ba ikamahanyang le mehlala ea moruo o chitja ba tla boloka kholo 'marakeng oa polasetiki o ntseng o fetoha.
