7. Nylon (Polyamide)
Cov Ntawv Thov Nylon
Nylon siv rau hauv cov ntaub los ua cov ntaub, nrog rau hauv cov khoom siv tshuab xws li cov iav thiab cov bearings. Nws lub zog kho tshuab thiab kev tiv thaiv kev hnav zoo ua rau nws yog ib qho kev xaiv dav dav hauv kev siv engineering.
8. Polycarbonate (PC)
Cov Ntawv Thov Polycarbonate
PC paub txog nws qhov kev tiv taus zoo heev thiab qhov pom kev zoo. Nws yog siv rau hauv kev tsim cov iav kev nyab xeeb, cov iav kho qhov muag, thiab cov khoom siv kho mob. Cov khoom no kuj ua rau nws siv ntau zaus hauv cov ntawv thov kev tsim kho muaj zog.
9. Polyurethane (PU)
Cov Ntawv Thov Polyurethane
PU siv tau ntau yam, suav nrog ua npuas ncauj uas yoog tau thiab tawv. Nws cov ntawv thov suav nrog cov txaj pw, cov ncoo, thiab cov khoom rwb thaiv tsev kub. Nws lub peev xwm los ua pwm rau ntau yam kev tawv thiab ductility ua rau PU muaj txiaj ntsig zoo rau ntau yam kev siv hauv kev lag luam.
10. Polytetrafluoroethylene (PTFE)
PTFE Daim Ntawv Thov
PTFE, uas paub zoo dua los ntawm lub npe lag luam Teflon, yog siv rau hauv cov ntawv thov uas xav tau kev tiv taus tshuaj lom neeg thiab kub siab, xws li gaskets, seals, thiab hluav taws xob rwb thaiv tsev.
