Cov ntaub thaiv npog tawg yog ua los ntawm cov khoom siv PC uas muaj zog (siab polymer). Cov khoom siv no sib xyaw ua ke siab zog nrog tsim nyog toughness. Nws muaj kev cuam tshuam zoo zog thiab puncture tsis kam, zoo cushioning thiab seismic kev ua tau zoo, thiab muaj zog, ruaj, thiab siv tau. Nws yog ib qho ntawm cov khoom pov thawj tawg-pov thawj zoo tshaj plaws tam sim no.
Cov ntaub thaiv npog lub cev ntawm cov ntaub thaiv npog yog ua los ntawm 3.0-3.5 hli tuab PC board. Lub teeb xa hluav taws xob ntawm lub cev tiv thaiv yuav tsum tsis pub tsawg dua 70 feem pua, thiab sab nraub qaum yog tsim los ntawm tuav thiab caj npab. Qhov dav ntawm cov ntaub thaiv npog yuav tsum tsis pub tsawg tshaj 500 hli, thiab qhov chaw tiv thaiv yuav tsum tsis pub tsawg tshaj 0.45m2. Lub cev tiv thaiv kev kub ntxhov tau txais cov qauv ntawm lub zos convex nto, convex platform thiab ntug qhov cuab lub zog, uas txhim kho lub peev xwm tiv thaiv kev tawm tsam. Cov ntaub thaiv npog lub cev yog ua los ntawm cov khoom siv PC uas muaj zog tuaj tom qab kev kho mob thiab txhaj tshuaj molded rau hauv pwm, uas muaj kev ua tau zoo heev thiab txuas ntxiv nws lub neej kev pab cuam.
