Polyurethane synthesis

synthesis of polyurethane

[@p.lydiafestuskanmani337]

Wonderfully done. Can you suggest a paper for reference where I can see details on concentration, time, RPM, etc.?

[@yousefdehghani2050]

Concentration 1:1 polyol iso cyanate

[@yousefdehghani2050]

Time 30 min

Hey . Can u guide me on how to synthesise thermoplastic polyurethane ?? With polyol , MDI and diol?

[@yousefdehghani2050]

Bro that's a deep technology

[@UaExRacer]

"stir gently", by putting the RPM on max.

Hi bro.
Can you help me for making polyéthylène glycol (PEG) ?

[@douro20]

I wonder if you could make expanded polyurethane from this by reacting the excess diisocyanate with formic acid...

[@mustafakhalil007]

is that process for thermoplastic or thermosetting PU?

[@rangarajan117]

Can we make polyol in home research... Only POLYOL i mean

[@magnuswootton6181]

i think its just some clever distilling, but watch out if u breathe in fumes - CAN KILL U!!!

[@saurabhjha_158]

I have tried keeping nco oh ratio one , but my precipitate is not hard, i tired of this,i am also using chain extender, please somebody help me

[@microflowmeter]

Great video, thanks!👋
If you need polyurethane resin epoxy resin precision flow meter, metering pump, please feel free to consult CIXIFM Winny,thanks~~🤪

[@sudeeplouis2058]

what type of polymerization method is this?

[@paroys]

how u can make a film based on that Polyurethane? can it be dissolved in solvent? like chloroform?

[@yousefdehghani2050]

Yes you can, use a pressure press tool

[@alarakaragoz9422]

is this suspension polymerization ?

[@ronakposhiya752]

At which temperature.

[@justusfelix2441]

Ronak Poshiya ~ 40°C
