Indwangu emelene nokusika esezingeni eliphezulu ilukwe umshini okhethekile ngokusebenzisa inhlanganisela entsha ye-ultra-high molecular weight polyethylene fiber kanye neminye imicu yezimboni (njengentambo yensimbi noma i-glass fiber).Inezici zamandla aphezulu, i-modulus ephezulu, isisindo esincane, ubude obuphansi ngesikhathi sekhefu, ukumelana nokugqoka, ukumelana nokusika, ukumelana nomthelela, ukumelana nokugqwala kwamakhemikhali, kanye nezakhiwo ezinhle zemishini.
