Barry : Welcome to the HellermannTyton ACADEMY the workshop for the professionals. I´m Barry ...
Mark : ... and I´m Mark.
Barry : And today Mark, we’ve had a lot of traffic on our channel ...
Mark : Yes.
Barry : ... about low temperature and flexibility.
Mark : OK Barry, well we have here one of our flexible heat shrink shapes.
Barry : Perfect, so what are we going to do with this?
Mark : I think Barry we need to demonstrate ...
... to our viewers how to apply it.
Barry : OK, so we can use our TSA tape ...
... which has a very low operating temperature.
Mark : We can use our TSA200 tape, very low operating temperature, ...
Barry : Perfect.
Mark : ... comes on a 100ft reel.
Barry : OK. And it’s specified to SCX15111 and SCX15112.
Mark : It is indeed.
Barry : So perfect for our -8 and -9 material. Mark : It is, yes Barry.
Barry : Right so, let’s get cracking. We don’t just say it, we do it.
Mark : We do it.
So Barry first of all we need to clean the cable.
Barry : OK. Why do we do this Mark?
Mark : So we clean the cable Barry to get ...
... rid of all that grease and all that grime. We have to make sure the cable´s nice and clean.
Barry : Don’t forget to clean your connectors as well guys, because they get dirty too.
Mark : So Barry you want to clean.
Barry : Yes. Mark : So we also, on this one, clean the ...
... inside of the heat shrink shape, again to get rid of all the grease and all the grime, ...
... people might have put their fingers in there.
Barry : Yes and we need to mention as well ...
... that all our products are washed before they leave the factory, ...
Mark : Indeed they are.
Barry : ... but we also recommend you clean them ...
... just in case. OK now we´re ready.
Mark : So Barry, now we have to abrade it.
Barry : Our trusty abrasive paper.
Mark : So again we always abrade up and down on the cable.
Barry : And if you haven’t seen us do this before, why not?!
Mark : Please click on our videos. Barry : So you need to ceck on our links below.
Barry : OK and we´ll do the boot too, ...
... and these boots are very thin Mark, aren’t they?
Mark : They are very thin Barry and that will mean they will shrink really quickly.
Barry : OK. So next stage, dry wipe.
Mark : OK Barry, so there’s a dry wipe.
We now have to get rid of all that dust. You can actually see some of it here on the bench.
Barry : Yes.
Mark : So this will enable us to have a nice good bond with the heat shrink shape onto the cable.
Barry : Yep. So, tape. Mark : Tape.
Barry : Lets warm the heat gun up while you´re talking.
Mark : Ok Barry. So this is our TSA. I have already cut ... Barry : Perfect, ...
Mark : ... some to size for you.
Barry : ... and there is a hot tip for this, so camer, close up.
So, because this is a hot melt, Mark ...
Mark : Yes Barry.
Barry : ... we can tack it into position so with 2 ½ wraps.
Mark : So this is like we did with the HMT200 Tape.
Barry : Correct, yes.
So there we go.
Mark : There you go.
Barry : Our trusty screwdriver ...
... and then we just ...
... should be OK, but we´ll just make sure a second time though, ...
Right. We´re good to go.
Mark : So Barry on with your gloves.
Barry : Yes.
So yes we can post-terminate.
Mark : Yes.
Barry : Have a H and a J end.
Mark : Yes and the H end is always the one that goes onto the connector.
Barry : OK so let’s go.
So the heat gun is set at 250°C.
Mark : Yeah, and because it´s really thin it... will shrink very quickly ...
So that enables it to be very very flexible.
Barry : Lets have the second bit of tape Mark.
Let´s take my gloves off for a second just to make sure we get it in the right place.
Mark : So more tape then, Barry going round. Barry : So we can push this back.
Mark : So that´s good then Barry we can actually push the boot back so we can actually put the adhesive in the J end.
Barry : In the correct place.
Mark : So we don’t have to pre-apply it to the J end prior.
Barry : No.
Barry : Like so. It´s nice and tight.
Screwdriver Mark?
Mark : There you go Barry.
Barry : Thank you.
So where would we use this ...
... sort of product Mark, if we had and application?
Mark : Well Barry I think this is normally for the aerospace industry.
Barry : So we carry on shrinking.
Mark : So what happens after the shrinkage then Barry?
Barry : Well it recovers onto the adhesive and then the adhesive needs to be cooked or ...
... post-cured for another 180 seconds.
Mark : So for three minutes.
Barry : Yes.
Mark : So we need to carry on applying heat for another three minutes?
Barry : Correct.
So there we go. Installed.
And now Mark we need to test this at a low temperature so I need, I’ve got a very, ...
Mark : ... Very special test ... Barry : ... very special test for you.
So this is replicating a high altitude application.
Mark : Right OK.
Barry : You can see that’s pretty cold.
Mark : Yeah, and this is still flexible!
Barry : Oh yes of course: it’s a HellermannTyton product.
Mark : Of course, indeed.
Barry : So we do our standard bend test ...
... and it works perfectly.
Mark : Good.
Barry : Another successful demonstration. Mark : Yes.
Barry : So I'm Barry ... Mark : ... and I’m Mark.
Barry : We hope you’ve enjoyed our demonstration.
Please like us and subscribe to our channel ...
... and we´ll see you again soon.
Mark : Bye bye.
Barry : Fancy a drink? Mark : Yeah, I need a drink.
Barry : Something cool. Mark : Indeed, something cool. Ha ha ha.
Barry : Do you know what, I really love this job.
Mark : So do I. Barry : Cheers.
