Donfoam 901 dej puag benld polyols rau pouring
Donfoam 901 dej puag benld polyols rau pouring
INTRODUTION
Cov khoom no yog ib hom kev sib xyaw polyols nrog 100% dej ua tus neeg sawv cev tshuab, uas tau tshawb fawb tshwj xeeb rau cov tawv PUF.Cov yam ntxwv yog raws li nram no:
(1) zoo flowability, Haum rau ib zaug pouring.
(2) zoo heev ua npuas ncauj mechanical zog
(3) zoo heev / tsis tshua muaj kub qhov ntev stability
