1. Fa'atomuaga
O le Polystyrene (PS) o se polymer thermoplastic e tele ona aogā ma taugofie e faʻaaogaina lautele i afifiina, oloa faʻatau, ma galuega faufale. E maua i ni foliga autu se lua—General Purpose Polystyrene (GPPS, manino lelei) ma le High Impact Polystyrene (HIPS, faʻamaʻaʻaina i le paʻu)—e taua le PS ona o lona maʻaʻa, faigofie ona faʻagasolo, ma le taugofie. O lenei tusiga e suʻesuʻeina ai meatotino o le PS palasitika, faʻaoga autu, metotia faʻagasolo, ma le vaʻaiga i le maketi.
2. Uiga o le Polystyrene (PS)
E ofoina atu e le PS ni uiga tulaga ese e faʻatatau i lona ituaiga:
A. Polystyrene mo le Fa'amoemoega Lautele (GPPS)
- Manino Lelei o le Va'aiga – E manino, e pei o se tioata.
- Ma'a'a ma Gatete – Malo ae faigofie ona māvaevae pe a mafatia.
- Mama – Māmā tele (~1.04–1.06 g/cm³).
- Mea e Fa'amama ai Mea Eletise - E fa'aaogaina i mea fa'aeletoronika ma mea e lafoa'i.
- Tete'e atu i vaila'au fa'akemikolo – E tete'e atu i le vai, 'āsi, ma alkalis ae e fa'a'a'a i vaila'au fa'a'asu e pei o le acetone.
B. Polystyrene Maualuga le Aafiaga (HIPS)
- Fa'aleleia atili o le Malosi – O lo'o iai le 5–10% polibutadiene rubber e tete'e atu ai i se a'afiaga.
- Foliga Vaaia - E le manino tele nai lo le GPPS.
- Faigofie ona Fa'avevela – E fetaui lelei mo afifiina o mea'ai ma pusa e lafoa'i.
3. Fa'aoga Autu o le PS Palasitika
A. Alamanuia o Afifiina
- Pusa Mea'ai (Ipu e lafoa'i, atigi mea'ai, naifi)
- Pusa CD ma DVD
- Foam Puipui (EPS – Expanded Polystyrene) – E fa'aaogaina i le afifiina o pinati ma mea e fa'amafanafana ai.
B. Oloa Fa'atau
- Mea Ta'alo ma Pepa Fa'aeletise (piliki e pei o le LEGO, pusa peni)
- Pusa Teuteu (Pusa laiti, paipa vali laugutu)
C. Mea Fa'aeletoronika ma Meafaigaluega
- Laina o le Pusaaisa
- Ufiufi Fa'aaliga Manino (GPPS)
D. Fausiaina ma le Puipuiga o le ea
- Papa Foam EPS (Fa'amafanafana fale, sima mama)
- Fa'a'ofu teuteu
4. Auala e Fa'agasolo ai mo le PS Palasitika
E mafai ona gaosia le PS e faʻaaoga ai le tele o metotia:
- Fa'a'ofuofu Tui (E masani ona fa'aaogaina mo oloa ma'a'a e pei o naifi)
- Fa'aoso (Mo pepa, ata tifaga, ma talaaga)
- Fa'avevela (Fa'aaogaina i afifiina o mea'ai)
- Foam Molding (EPS) – PS fa'alauteleina mo le fa'amafanafana ma le fa'amalūlūina.
5. Aga Masani ma Luʻitau o le Maketi (Vaʻaiga o le 2025)
A. Fa'aauauina ma Fa'amalosiaga Fa'atonutonu
- Fa'asāina o PS e Fa'aaogā Tasi – E fa'asāina e le tele o atunuu oloa PS e lafoa'i (e pei o le Fa'atonuga a le EU mo Palasitika e Fa'aaogā Tasi).
- PS Toe Fa'aaogāina & Fa'avae i Meaola – O le mana'oga fa'atupula'ia mo isi auala e le afaina ai le si'osi'omaga.
B. Tauvaga mai Palasitika Eseese
- Polypropylene (PP) – E sili atu ona tete'e i le vevela ma umi mo afifiina o mea'ai.
- PET & PLA – Fa'aaogaina i afifiina e mafai ona toe fa'aaogaina/pala.
C. Faiga Fa'atino o Maketi Fa'aitulagi
- E pulea e Asia ma le Pasefika (Saina, Initia) le gaosiga ma le fa'aaogaina o PS.
- E taula'i Amerika i Matu ma Europa i le toe fa'aaogaina ma le EPS insulation.
- E teu fa'afaigaluega e Sasa'e Tutotonu le gaosiga o le PS ona o tau maualalo o mea e fafaga ai.
6. Faaiuga
O loʻo tumau pea le Polystyrene o se palasitika taua i afifiina ma oloa faʻatau ona o lona tau maualalo ma le faigofie ona faʻagasolo. Peitaʻi, o popolega i le siosiomaga ma faʻasā faʻatonutonu i luga o le PS e faʻaaogaina tasi o loʻo faʻamalosia ai le faʻafouga i le toe faʻaaogaina ma isi mea e faʻavae i luga o meaola. O le fetuʻunaʻi o kamupani gaosi oloa i faʻataʻitaʻiga o le tamaoaiga faʻataʻamilomilo o le a faʻatumauina le tuputupu aʻe i le maketi palasitika o loʻo faʻagasolo pea.
