INTSHAYELELO

I-DonSpray504 yi-polyols yomxube wokutshiza, i-agent evuthelayo yi-245fa endaweni ye-HCFC-141B, isabela nge-isocyanate ukuvelisa amagwebu asebenza kakuhle, alandelayo,

1) iiseli ezintle kunye nezifanayo

2) i-conductivity ephantsi ye-thermal

3) ukumelana nomlilo ogqibeleleyo

4) Uzinzo oluhle lomgangatho ophantsi wobushushu.

Isebenza kuzo zonke iintlobo zobunjineli bokufakelwa kwe-thermal obusebenzisa ubuchwepheshe bokutshiza, njengamagumbi abandayo, iimbiza, imibhobho emikhulu kunye ne-metope yokwakha njl.
