He mea polymer elastic loa ka Rubber me ka deformation hiki ke hoʻohuli ʻia.

He elastic ia i ka mahana o loko a hiki ke hana i ka deformation nui ma lalo o ka hana a kahi ikaika liʻiliʻi o waho.Hiki iā ia ke hoʻi i kona kūlana mua ma hope o ka wehe ʻana o ka mana o waho.

Nui nā ʻano laholio e like me ka EPDM, Neoprene Rubber, Viton, Natural Rubber, Nitrile Rubber, Butyl Rubber, Timprene, Synthetic Rubber, a me nā mea ʻē aʻe.
