(1) tag nrho ntawm elasticity thiab resilience;

(2) tus muaj zog thev naus laus zis tsim nyog, suav nrog nthuav zog, elongation thiab tensile lub zog, thiab lwm yam.

(3) qhov kev ua haujlwm ruaj khov, tsis yooj yim o hauv nruab nrab, me me cua sov shrinkage nyhuv (joule nyhuv).

(4) yooj yim rau kev siv tshuab molding, thiab tuaj yeem khaws qhov precision ntawm qhov loj me.

(5) tsis muaj kev sib cuag xeb, tsis muaj kuab paug nruab nrab, thiab lwm yam.

Ua tau raws li cov lus sau tseg saum toj tshaj plaws thiab cov khoom siv feem ntau yog cov roj hmab, yog li lub nplhaib sib khi feem ntau yog ua los ntawm cov khoom siv roj hmab.Ib ntau cov roj hmab, thiab tas li muaj cov roj hmab hom tshiab, tsim qauv thiab xaiv, yuav tsum nkag siab cov yam ntxwv ntawm txhua yam roj hmab, xaiv qhov tsim nyog.
