Ko te Kevlar he rauemi tino kaha, he mahi i muri i te polymerization, te toronga, te hurihuri, me te kaha o te wera me te kaha nui. Ka rite ki te taura he kaha teitei , rerekētanga pāmahana(-40°C~500°C) waikura waikura ~ mahi ātete, iti painga elongation.
Taupānga: Kei te whakamahia te nuinga mo te mahi teitei o te wera, te kaipuke motuhake, te miihini hiko, nga mahi moana, nga momo momo kotaha, te aukati, te rangahau hoia me etahi atu mara.
