(1) heev elastic thiab resilient;
(2) Tsim nyog mechanical zog,nrog rau kev nthuav dav zog, elongation thiab compressive zog,lwm.
(3) Cov yam ntxwv ruaj khov, nws tsis yooj yim rau o ntawm cov khoom, thiab cov nyhuv thermal shrinkage (Joule effect) yog me me.
(4) Kev tsim khoom yooj yim molding, thiab tuaj yeem tswj tau qhov loj me.
(5) tsis muaj etch cheeb tsam, tsis muaj kuab paug, thiab lwm yam.
