1. Isingeniso
I-Polystyrene (PS) iyi-polymer ye-thermoplastic eguquguqukayo futhi engabizi kakhulu esetshenziswa kakhulu ekupakisheni, ezimpahleni zabathengi, nasekwakhiweni. Itholakala ngezinhlobo ezimbili eziyinhloko—I-General Purpose Polystyrene (i-GPPS, i-crystal clear) ne-High Impact Polystyrene (i-HIPS, iqiniswe ngenjoloba)—I-PS ibaluleke kakhulu ngenxa yokuqina kwayo, ukucutshungulwa kalula, nokufinyeleleka kwayo. Lesi sihloko sihlola izakhiwo zepulasitiki ye-PS, izinhlelo zokusebenza ezibalulekile, izindlela zokucubungula, kanye nokubukeka kwemakethe.
2. Izakhiwo ze-Polystyrene (PS)
I-PS inikeza izici ezihlukile ngokuya ngohlobo lwayo:
A. General Purpose Polystyrene (GPPS)
- I-Optical Clarity - Ukubukeka okusobala, okufana nengilazi.
- Ukuqina & Nokuqina - Kunzima kodwa kujwayele ukuqhekeka ngaphansi kwengcindezi.
- Isisindo esincane – Ukuminyana okuphansi (~1.04–1.06 g/cm³).
- I-Electrical Insulation - Isetshenziswa ezintweni zikagesi nasezintweni ezilahlwayo.
- I-Chemical Resistance - Imelana namanzi, ama-acids, nama-alkali kodwa incibilika kuzincibilikisi njenge-acetone.
B. I-High Impact Polystyrene (HIPS)
- Ukuqina Okuthuthukisiwe - Iqukethe irabha ye-polybutadiene engu-5–10% yokumelana nomthelela.
- Ukubukeka Kwe-Opaque - Okuncane okusobala kune-GPPS.
- I-Thermoforming Elula - Ilungele ukupakishwa kokudla neziqukathi ezilahlwayo.
3. Izicelo Ezibalulekile ze-PS Plastic
A. Imboni yokupakisha
- Iziqukathi zokudla (izinkomishi ezilahlwayo, amagobolondo, izinto zokusika)
- Amacala e-CD & DVD
- Igwebu Elivikelayo (EPS – I-Polystyrene Enwetshiwe) – Isetshenziswa ekupakisheni amantongomane kanye nokwahlukanisa.
B. Izimpahla Zabathengi
- Amathoyizi nezinto zokubhala (izitini ezifana ne-LEGO, amakheshi epeni)
- Iziqukathi Zezimonyo (Amakesi ahlangene, amashubhu e-lipstick)
C. Ezogesi Nezisetshenziswa zikagesi
- Isiqandisi Liners
- Amakhava e-Transparent Display (GPPS)
D. Construction & Insulation
- I-EPS Foam Boards (I-insulation yokwakha, ukhonkolo ongasindi)
- Ama-Decorative Moldings
4. Izindlela Zokucubungula ze-PS Plastic
I-PS ingenziwa kusetshenziswa amasu amaningana:
- Ukubumba Umjovo (Okuvamile emikhiqizweni eqinile efana ne-cutlery)
- I-Extrusion (Okwamashidi, amafilimu, namaphrofayili)
- I-Thermoforming (Isetshenziswa ekufakweni kokudla)
- I-Foam Molding (EPS) - I-PS Enwetshiwe yokufaka nokufaka i-cushioning.
5. Amathrendi nezinselelo zemakethe (2025 Outlook)
A. Ukusimama Nezingcindezi Zokulawula
- Ukuvinjelwa Kwe-PS Yokusetshenziswa Okukodwa – Amazwe amaningi abekela imingcele imikhiqizo ye-PS elahlwayo (isb., I-EU's Single-Use Plastics Directive).
- I-PS Esenziwe Kabusha kanye Ne-Bio-Based - Isidingo esikhulayo sezinye izindlela ezilungele imvelo.
B. Ukuncintisana kwe-Alternative Plastics
- I-Polypropylene (PP) - Imelana nokushisa eyengeziwe futhi ihlala isikhathi eside ekufakweni kokudla.
- I-PET ne-PLA - Isetshenziswa ekufakweni okugaywa kabusha/okubolayo.
C. I-Regional Market Dynamics
- I-Asia-Pacific (China, India) ibusa ukukhiqizwa nokusetshenziswa kwe-PS.
- I-North America ne-Europe igxile ekugayweni kabusha kanye nokufakwa kwe-EPS.
- I-Middle East itshala imali ekukhiqizeni i-PS ngenxa yezindleko eziphansi ze-feedstock.
6. Isiphetho
I-Polystyrene ihlala iyipulasitiki eyinhloko ekufakweni nasezimpahleni zabathengi ngenxa yezindleko zayo eziphansi kanye nokulula kokucubungula. Kodwa-ke, ukukhathazeka kwemvelo kanye nokuvinjelwa okungokomthetho kokusetshenziswa okukodwa kwe-PS kuqhuba ubuciko obusha ekusetshenzisweni kabusha kanye nezinye izindlela ezisekelwe ku-bio. Abakhiqizi abajwayela amamodeli womnotho oyindilinga bazosimamisa ukukhula emakethe yepulasitiki eguqukayo.
