I. Cov khoom sib txawv
PP casters feem ntau yog ua los ntawm cov khoom siv polypropylene, thaum TPR casters yog ua los ntawm cov khoom siv roj hmab thermoplastic. Qhov xwm thiab cov yam ntxwv ntawm ob yam khoom no txawv heev.

Polypropylene (PP): Polypropylene yog semi-crystalline thermoplastic, muaj kev cuam tshuam zoo thiab tshuaj lom neeg, thiab yooj yim rau txheej txheem.
Thermoplastic roj hmab (TPR): Cov roj hmab thermoplastic yog ib hom thermoplastic nrog roj hmab elasticity, zoo saj zawg zog thiab hnav tsis kam, TPR casters feem ntau muaj softer kev ntxhib los mos, haum rau lub sij hawm uas yuav tsum tau cushioning thiab silence.

Thib ob, kev ua haujlwm zoo
Abrasion Resistance: Qhov kev puas tsuaj ntawm TPR casters yog qhov zoo tshaj ntawm PP casters vim nws muaj qhov softer saum npoo uas hloov tau zoo dua rau hauv av.
Impact resistance: Txawm hais tias PP casters muaj kev cuam tshuam zoo dua, qee zaum, TPR casters yuav muaj kev cuam tshuam zoo dua.
Processability: PP casters yog ib qho yooj yim rau txheej txheem thiab tuaj yeem txhaj molded ntawm qhov kub thiab txias. TPR casters yog cov txheej txheem tsawg dua thiab feem ntau yuav tsum tau siv cov kev txhaj tshuaj thib ob.
Nqe: Feem ntau, TPR casters yog kim dua PP casters vim yog cov txheej txheem ntau lawm.

Daim ntawv thov
PP casters: haum rau lub sijhawm uas yuav tsum tau muaj peev xwm nqa tau siab thiab hnav tsis kam, xws li cov khoom hnyav, txee, thiab lwm yam.
TPR casters: tsim nyog rau qhov xav tau kev hloov pauv tau zoo, muaj kev cuam tshuam zoo, hnav tsis kam, xws li cov khoom siv kho mob, cov khoom siv kuaj.
