Izinzuzo zesikhwama sokuhlunga se-PPS:
Isikhwama sokuhlunga se-1.PPS sinokuzinza okuhle kokushisa, ukuzinza kokushisa kokusetshenziswa okusheshayo kanye nesikhathi eside okuqhubekayo kwazo zonke izinto zokuhlunga zobunjiniyela zamanje.
2. Ukumelana nokugqwala okuhle.
3. Izakhiwo zomzimba nezemishini.Isikhwama sokuhlunga se-PPS sine-fluidity enhle futhi kulula ukuthintana okumanzi nge-glass fiber, ngakho kulula ukusigcwalisa.Imicu yengilazi noma izigcwalisi ezingaphili zemicu yengilazi zisetshenziselwa ukuqinisa amandla aqinile, ukumelana nomthelela, ukugoba kanye nokwelulwa kwempahla yesikhwama sesihlungi se-PPS.
Isikhwama sokuhlunga se-4.PPS sinokumelana kahle nokukhuphuka, i-coefficient ephansi yokunwetshwa komugqa kanye nokuzinza okuhle kwe-dimensional.)
