Nylon 66

And then the question from Mr. Zalp says, OK, and they're a little bit different, aren't they? Yes, they are.

OK, how does a person such as you determine that it's nylon 66? Is there a picture book you go to and or? No, I don't mean I'm not.

I know it sounds humorous.

Is there a book somewhere you go to? And well, we have a number of sources.

Will you give me any of the literature? Yes.

Okay.

that you used to try to identify this as nylon 66? I'll give you some of it.

Some of it, you know, I use it without really, okay, realizing I'm using it.

Well, you might use a PFAS-free PBT.

Or a PA66 grade.

But if that bus bar is running in an environment with extreme continuous heat, say, in the 150 to 180 degrees Celsius range, that is where you have to deploy a 40% glass fiber PPS grade.

Like in Veluer's G4024T.

We're looking at up to 140 or 150 amps per contact at 48 volts.

And here, we have to draw a sharp distinction between how the connector physically attaches to the motherboard.

If it's a traditional through-hole connector housing, where the pins go through the board and are soldered from underneath, you're typically looking at PA66 or PBT grades.

Because through-hole wave soldering is generally less thermally abusive to the actual plastic connector housing itself, the heat is applied below the board.

So we produce something like 120 tons of textile waste a year and less than 1% of that is actually recycled back into new fiber.

And for Nylon 66 especially, it's the same story, about 2 million tons waste every year and then less than 1% recovered.

So why is that number so stubbornly low? What is it about nylon that makes it so hard to recycle?

I think what makes it hard to recycle is what makes it really desirable in the first place, which is that it's incredibly strong material.

They won't be happy until they've actually made a tangible impact on what is a very important sustainability issue.

So I think, you know, for us, we won't be happy unless in that sort of time horizon, five to eight years, we are having a major impact on the way that the world's materials are made.

We've talked about PA66, nylon 66 that is.

In five to eight years, we will have multiple production facilities up and running by then.

same brand, same weave standards, what's the actual difference between

500 and the 1000? Abrasion resistance is the main one, and this gets to what actually makes Cordura different from generic nylon in the first place.

The key is air texturing.

After the nylon is spun, Cordura blasts it with high-pressure air jets.

That bulks up the yarn, makes it fuzzy under a microscope, way more surface area than a smooth nylon filament.

When something rubs against it, the friction distributes across all that extra surface.

So it's not that the nylon itself is a different polymer.

It's the geometry of the yarn.
