Cov ntaub ntawv SPUA tsis tsuas yog muaj lub peev xwm los kho qhov nyuaj ntawm qhov ntau (ntawm shao A30 mus rau shao D65), tab sis kuj tseem tswj tau kub tsis tshua zoo nyob rau hauv cov tawv tawv. Ua tiav tuaj yeem tiv thaiv qhov cua sov nthuav tawm thiab txias txias tau nqa los ntawm qhov hloov ntawm hnub kub thiab hmo ntuj, plaub lub caij, tsis muaj qhov tawg thiab ntog, nws yog hom tshiab ntawm txheej pem teb / pem teb. Ntawm lawv, ntshiab aliphatic SPUA cov ntaub ntawv npaj los ntawm aliphatic isocyanate (xws li m-tmxdi) thiab JEFFAMINE @polyether thiab JEFFAMINE8 qis-molecular binary amine saw extender (xws li d-230 thiab t-403) muaj qhov ua tau zoo tshaj plaws. Qhov ntsuas kub tsawg-ua kom tawv ntawm SPUA cov ntaub ntawv zoo nkauj kuj tseem zoo, tab sis tsawg dua li aliphatic SPUA cov ntaub ntawv
Nws tau tshaj tawm tias SPUA cov ntaub ntawv tau txau rau saum nplaim hlau, pob zeb thiab asphalt feem. Cov kua roj nitrogen ntawm -196 ° C tau txau rau saum npoo ntawm qhov ntsuas mus rau 30 vib nas this ntawm qhov ntev ntawm 30.5 cm ntawm lo. Tsis pom txheej txheej puas pom. Thaum cov tshuaj tsuag nrug raug txo kom tsawg li 10.2 centimeters, cov hlau thiab pob zeb ua kom tawg tau tawg me ntsis, thaum lub npov asphalt tseem zoo li qub.
