Ua npuas ncauj yas tseem hu ua porous yas. Ib qho yas nrog ntau micropores sab hauv, ua los ntawm cov cob ua cov khoom siv tseem ceeb. Lub teeb, cua sov-insulating, suab-absorbing, poob siab- pov thawj thiab corrosion-resistant. Muaj cov ntsiab lus mos thiab tawv. Nws yog dav siv los ua cua sov rwb thaiv tsev, suab rwb thaiv tsev, ntim khoom thiab lub tsheb thiab nkoj plhaub.
Piv nrog cov yas ntshiab, cov yas ua npuas dej muaj qhov ntom ntom, lub teeb yuag thiab lub zog tshwj xeeb. Nws lub zog nce nrog qhov nce ntawm qhov ceev. Nws muaj peev xwm nqus tau qhov cuam tshuam, zoo heev cushioning thiab poob siab absorbing kev ua tau zoo, suab rwb thaiv tsev thiab suab nqus kev ua tau zoo, thiab thermal conductivity. Tsawg, zoo thermal rwb thaiv tsev kev ua tau zoo, zoo hluav taws xob rwb thaiv tsev kev ua tau zoo, corrosion kuj thiab mildew kuj. Flexible foam muaj zoo elasticity thiab lwm yam khoom.
Yas nrog ntau me me pores sab hauv. Nws yog tsim los ntawm kev siv tshuab (txhaj cua lossis carbon dioxide thaum ua cov tshuab nplawm kom nws ua npuas dej) lossis cov txheej txheem tshuaj (ntxiv tus neeg sawv cev foaming). Muaj ob hom: kaw cell hom thiab qhib cell hom. Cov pores nyob rau hauv lub kaw cell hom yog cais los ntawm ib leeg thiab muaj floating zog; cov pores nyob rau hauv lub qhib cell hom yog txuas rau ib leeg thiab tsis muaj floating zog. Nws tuaj yeem ua los ntawm polystyrene, polyvinyl chloride, polyurethane thiab lwm yam resins. Nws tuaj yeem siv los ua cov rwb thaiv tsev kub thiab cov khoom siv suab rwb thaiv tsev thiab muaj ntau yam kev siv.
(1) The bulk density is very low, which can reduce packaging weight and reduce transportation costs;
(2) Nws muaj kev poob siab zoo heev thiab kev co lub zog nqus, uas tuaj yeem txo cov khoom puas tsuaj thaum siv cushioning thiab shockproof ntim;
(3) Muaj zog yoog raws qhov kub thiab av noo hloov pauv, thiab tuaj yeem ua tau raws li cov kev xav tau ntawm kev ntim khoom dav dav;
(4) Kev nqus dej tsawg, tsis muaj hygroscopicity, zoo tshuaj ruaj khov, nws yuav tsis corrode cov ntsiab lus, thiab muaj zog tiv thaiv acids, alkalis thiab lwm yam tshuaj;
(5) Tsis tshua muaj thermal conductivity, tuaj yeem siv rau kev ntim khoom thermal, xws li khob dej khov, ntim khoom noj ceev thiab cov thawv ntses thermal, thiab lwm yam;
(6) Nws yog ib qho yooj yim rau kev tsim thiab txheej txheem, thiab ntau yam ntaub ntawv ua npuas ncauj, ua npuas ncauj blocks, nplooj ntawv, thiab lwm yam tuaj yeem ua los ntawm molding, extrusion, txhaj tshuaj thiab lwm txoj kev molding. Nws yog ib qho yooj yim mus nqa tawm theem nrab molding ua, xws li daim ntawv ua npuas ncauj yuav ua tau rau hauv ntau yam khoom noj ceev ntim tom qab thermoforming. Tsis tas li ntawd, cov khoom ua npuas ncauj kuj tuaj yeem txuas nrog cov nplaum lossis lwm yam ntaub ntawv los ua ntau yam ntaub ntawv cushioning.
