1. Selelekela
Polystyrene (PS) ke polymer ea thermoplastic e feto-fetohang le e theko e phahameng e sebelisoang haholo ho paka, thepa ea bareki le kaho. E fumaneha ka mefuta e ’meli ea sehlooho—General Purpose Polystyrene (GPPS, crystal clear) le High Impact Polystyrene (HIPS, e thatafalitsoeng ka rabara)—PS e nkoa e le ea bohlokoa ka lebaka la ho tiea ha eona, ho sebetsa habonolo ha eona le ho khoneha. Sengoliloeng sena se hlahloba thepa ea polasetiki ea PS, lits'ebetso tsa bohlokoa, mekhoa ea ts'ebetso le pono ea mmaraka.
2. Thepa ea Polystyrene (PS)
PS e fana ka litšobotsi tse ikhethang ho latela mofuta oa eona:
A. Kakaretso Polystyrene (GPPS)
- Optical Clarity - Ponahalo e hlakileng, e kang ea khalase.
- Rigidity & Brittleness - E thata empa e tloaetse ho robeha tlas'a khatello ea maikutlo.
- Bobebe - Boima bo tlase (~1.04–1.06 g/cm³).
- Insulation ea Motlakase - E sebelisoa linthong tsa elektroniki le lintho tse ka lahloang.
- Khanyetso ea Lik'hemik'hale - E hanana le metsi, li-acids le alkalis empa e qhibiliha ka har'a metsoako e kang acetone.
B. High Impact Polystyrene (HIPS)
- Matla a Ntlafetseng - E na le rabara ea polybutadiene ea 5-10% bakeng sa ho hanyetsa tšusumetso.
- Ponahalo e Opaque - Ha e pepesehetse ho feta GPPS.
- Thermoforming e Bonolo - E loketse ho paka lijo le lijana tse lahloang.
3. Lisebelisoa tsa bohlokoa tsa PS Plastic
A. Indasteri ea ho paka
- Lits'oants'o tsa Lijo (Likopi tse lahliloeng, li-clamshell, li-cutlery)
- Linyeoe tsa CD & DVD
- Protective Foam (EPS - Expanded Polystyrene) - E sebelisoa ho paka matokomane le ho koala.
B. Thepa ea Bareki
- Lintho tsa ho bapala le Lingoliloeng (litene tse kang LEGO, mekotla ea pene)
- Lijana tsa Cosmetic (Likhetla tse kopaneng, li-lipstick tubes)
C. Lisebelisoa tsa Elektronike le Lisebelisoa
- Li-Liners tsa Sehatsetsing
- Transparent Display Cover (GPPS)
D. Kaho & Insulation
- EPS Foam Boards (Mohaho oa moaho, konkreite e bobebe)
- Mekhabiso ea Moulding
4. Mekhoa ea ho sebetsa bakeng sa PS Plastic
PS e ka etsoa ho sebelisoa mekhoa e mengata:
- Ente Molding (E tloaelehileng bakeng sa lihlahisoa tse thata joalo ka li-cutlery)
- Extrusion (Bakeng sa maqephe, lifilimi, le litlaleho)
- Thermoforming (E sebelisoa ka har'a liphutheloana tsa lijo)
- Foam Molding (EPS) - E atolositsoeng PS bakeng sa ho kenya letsoho le ho thibela.
5. Mekhoa ea 'Maraka le Liphephetso (Pono ea 2025)
A. Moshoelella & Khatello ea Taolo
- Lithibelo ho PS ea Ts'ebeliso e le 'Ngoe - Linaha tse ngata li thibela lihlahisoa tsa PS tse lahloang (mohlala, Taelo ea EU's Sing- Use Plastics Directive).
- Recycled & Bio-Based PS - Tlhokahalo e ntseng e hola ea mekhoa e meng e sebelisang tikoloho.
B. Tlholisano e tsoang ho Alternative Plastics
- Polypropylene (PP) - E thibela mocheso haholoanyane ebile e tšoarella bakeng sa ho paka lijo.
- PET & PLA - E sebelisoa ka har'a sephutheloana se ka sebelisoang hape / se bolileng.
C. Matla a Maraka a Libaka
- Asia-Pacific (Chaena, India) e laola tlhahiso le tšebeliso ea PS.
- Amerika Leboea le Europe li tsepamisitse maikutlo ho recycling le EPS insulation.
- Middle East e tsetela tlhahisong ea PS ka lebaka la litšenyehelo tse tlase tsa phepelo.
6. Qetello
Polystyrene e ntse e le polasetiki ea bohlokoa ka ho paka le thepa ea bareki ka lebaka la theko e tlase le bonolo ba ho e sebetsa. Leha ho le joalo, mathata a tikoloho le lithibelo tsa taolo ho PS ea tšebeliso e le 'ngoe li etsa hore ho be le mekhoa e mecha ea ho tsosolosa le mekhoa e meng e thehiloeng ho bio. Baetsi ba ikamahanyang le mehlala ea moruo o chitja ba tla ts'ehetsa kholo ea 'maraka o ntseng o tsoela pele oa polasetiki.
