Airpole Technology Explained
I just want to describe an air pole, and how it works. Probably the best way of describing it is it's like an old football. If you take the bladder out of an old football and pump that up, it blows up to a much larger size than the football.
It's the skin of the football that keeps its shape and allows the pressure. It's much the same as with one of these air poles. This is just one of the sample poles that we have but,
There's a Boston valve on there which is where you pump it up,
And inside there's a bladder. Now the bladders oversized and it's made of a thing called Thermoplastic Polyurethane or TPU.
So this plastic has excellent characteristics for stretch, it can stretch up to quite a large size, but the sleeve that the bladder goes into is what gives it its shape and keeps its size.
They've also got some flexibility and they are strong and they'll spring back into shape.
So what I'm going to do here is, I'm going to pump this bladder up and show you that it can grow a lot larger than what the actual air pole is.
So you can see already it's getting larger. So we thought we'd have a bit of fun and see if we could burst this, and you can see, Look how big it's got compared to its normal size.
So you can see it's never going to burst inside this tube. I'm a bit puffed because I've been pumping for ages. It's still under 5 psi by the way.
