Hey, welcome to Tytan Professional videos. I’m James Davoli, the product manager. Today we’re answering a question. Why does foam expand? So this is a question that’s maybe familiar to some of you and maybe not so familiar to some of you.
And so we’re going to get down to is really the two questions, why does it expand? And more importantly, how does it expand?
So first off, why does PU foam like our TYTAN window and door? Why does it expand? Well, this PU foam expands because it’s made to fill the gaps or voids between the framing of this window. In the framing of this house. Okay.
So this PU foam, why it expands is to fill those gaps, provide an air tight water tight seal. So that way you have between your window frame in your house frame, no gap. So there’s not penetration of air and water. Instead, it’s being stopped by this PU foam like the TYTAN window and door foam. polyurethane foam works through absorbing humidity and releasing CO2. It causes the chain reaction when the foam starts to absorb humidity from the air, it actually starts to activate the chemicals.
So that’s why the foam doesn’t expand in the can because there’s no humidity in the can. But as soon as it gets shot out and it’s touching the atmosphere around, it’s absorbing the humidity, that H2O, it’s absorbing it, it’s causing a chemical reaction. And that chemical reaction is how the foam starts to expand.
That chemical reaction starts to cause bubbles. The CO2 being released causes the bubbles and that causes the foam to expand. And that’s exactly what you want when you’re trying to fill gaps and voids, especially at different depths.
So I hope this answered the question on why does polyurethane foam expand?
Well, to fill those gaps with voids in how through humidity in the air causes a chemical chain reaction. So thank you for these questions. If you have more, please like and comment on our video here. Tell us what else you have out there in the field. Thank you and have a great day.
