1. Intshayelelo
I-Polystyrene (PS) yipolymer ye-thermoplastic eguquguqukayo kunye neendleko ezisebenzayo esetyenziswa kakhulu ukupakisha, iimpahla zabathengi kunye nokwakha. Ifumaneka ngeendlela ezimbini eziphambili—General Purpose Polystyrene (GPPS, crystal clear) kunye neHigh Impact Polystyrene (HIPS, yenziwe yaqina ngerabha)—PS ixatyiswa ngenxa yokuqina kwayo, ukusetyenzwa ngokulula, nokufikeleleka kwayo. Eli nqaku liphonononga iipropati zeplastiki ze-PS, izicelo eziphambili, iindlela zokucubungula, kunye nembono yemarike.
2. Iipropati zePolystyrene (PS)
I-PS inikezela ngeempawu ezahlukileyo ngokuxhomekeke kuhlobo lwayo:
A. Injongo ngokubanzi Polystyrene (GPPS)
- I-Optical Clarity - Imbonakalo ecacileyo, efana neglasi.
- Ubungqongqo kunye nobuncinci-Kunzima kodwa kuthande ukuqhekeka phantsi koxinzelelo.
- UbuKhaphukhaphu – Ubuninzi obuphantsi (~1.04–1.06 g/cm³).
- I-Insulation yoMbane-Isetyenziswa kwizinto zombane kunye nezinto ezilahlayo.
- Ukumelana neeKhemikhali -Ukumelana namanzi, i-asidi, kunye ne-alkalis kodwa inyibilika kwizinyibilikisi njenge-acetone.
B. I-High Impact Polystyrene (HIPS)
- Ukuphucula Ukuqina - Iqulethe i-5-10% ye-polybutadiene irabha yokumelana nempembelelo.
- Inkangeleko eOpaque-Ngaphantsi ekuhleni kune-GPPS.
- I-Thermoforming elula-Ilungele ukupakishwa kokutya kunye nezikhongozeli ezilahlwayo.
3. Izicelo eziphambili zePlastiki yePS
A. Ishishini lokuPakisha
- Izikhongozeli zokutya (iikomityi ezilahlwayo, amaqokobhe eeclam, izinto zokusika)
- CD & DVD Cases
- I-Foam ekhuselayo (i-EPS - i-Polystyrene eyandisiweyo) - Isetyenziselwa ukupakisha amantongomane kunye nokugquma.
B. Iimpahla zabaThengi
- Izinto zokudlala kunye nezinto zokubhala (izitena ezifana ne-LEGO, iingxowa zosiba)
- Izikhongozeli zezithambiso (Iikesi ezibambeneyo, iityhubhu zelipstick)
C. Ii-Electronics & neZixhobo zombane
- Iifriji zeFriji
- Izigqubuthelo zokuBonisa eziNgaphandle (GPPS)
D. Ulwakhiwo kunye noKhuseleko
- Iibhodi ze-EPS zogwebu (I-insulation yokwakha, ikhonkrithi ekhaphukhaphu)
- Ukubumba okuhombisayo
4. Iindlela zokuSebenza zePlastiki yePS
I-PS inokuveliswa kusetyenziswa iindlela ezininzi:
- Isitofu sokubumba (Ixhaphakile kwiimveliso eziqinileyo ezifana nokusika)
- I-Extrusion (Yeyamaphepha, iifilimu, kunye neeprofayili)
- I-Thermoforming (Isetyenziswa kwipakethe yokutya)
- Ukubunjwa kwe-Foam (EPS) - I-PS eyandisiweyo yokugquma kunye ne-cushioning.
5. IiNdlela zeMarike kunye nemingeni (i-Outlook ka-2025)
A. Uzinzo kunye noxinzelelo lolawulo
- Ukuvalwa kokuSebenzisa okunye kwePS – Amazwe amaninzi azibekela imiqathango iimveliso ze-PS ezilahlwayo (umzekelo, uMyalelo wePlastiki wokuSebenzisa kanye we-EU).
- IRecycled & Bio-Based PS-Imfuno ekhulayo yeendlela ezizezinye ezilungele indalo.
B. Ukhuphiswano oluvela kwiiPlastiki ezizezinye
- I-Polypropylene (PP) - Ukushisa okungaphezulu kunye nokuqina kokupakishwa kokutya.
- I-PET & ne-PLA - Isetyenziswe kwipakethe enokuphinda isetyenziswe / i-biodegradable.
C. Uguqulo lweMarike yeNgingqi
- I-Asia-Pacific (i-China, i-Indiya) ilawula imveliso ye-PS kunye nokusetyenziswa.
- UMntla Melika kunye neYurophu zigxile ekusetyenzisweni ngokutsha kunye nokugqunywa kwe-EPS.
- I-Middle East ityala imali kwimveliso ye-PS ngenxa yeendleko eziphantsi zesondlo.
6. Isiphelo
I-Polystyrene ihlala iyiplastiki ephambili ekupakisheni kunye nempahla yabathengi ngenxa yeendleko zayo eziphantsi kunye nokulula ukusetyenzwa. Nangona kunjalo, iinkxalabo zokusingqongileyo kunye nokuvalwa kwemithetho yokusetyenziswa kwe-PS enye kuqhuba inguqulelo ekuhlaziyeni nasekusetyenzisweni kwezinto ezizezinye. Abavelisi abaziqhelanisa neemodeli zoqoqosho ezijikelezayo baya kugcina ukukhula kwimakethi yeplastiki eguqukayo.
