Would love some help finding a material like Hydlar in tube form !
Would love some help finding a material like Hydlar in tube form !
(OP)
Hello,
let me know if you think this thread belongs elsewhere, but I think it's under the subject of polymers... possibly composites too though...
Long story short, I'm on the hunt for a material that is more wear resistant than G10/FR4. My googling led me to find out about Hydlar, which is apparently more wear resistant than G10FR4, and also has higher dielectric strength - very desireable when using the material as an insulator in induction heating.
Hydlar looks perfect on paper (the specs are great), but the problem is, I need it in tube form, and I cannot find anyone online who manufactures it in tube form.
Any of you folks familiar with these types of materials like G10 and Hydlar? do you know of any material that may be as good as Hydlar regarding wear resistance and dielectric strength?
Thanks for any suggestions or ideas!

Some of the grades can be injection molded if the quantity is there.
Another approach is the fiber reinforced bearings materials. Here is a link to Tenmat, definately not the only one in he market that may have a solution to your problem.

I've emailed them and I'm waiting to hear back from them for some datasheets.
I'm unsure if ZM is the grade, but Hydlar ZM seems to have good wear resistance by the datasheets, forgive me I'm no materials guru, I'm more of an electronics guy (so thanks for the help!)
Ideally I would like to be able to have a 5ft long tube with an ID of say 1.25" and 1/4" to 1/8" thickness (the thinner the better).
Thanks again

5'long 1.25"ID tube will not be possible by injection moulding in one piece but extrusion should be possible if you have enough volume for tooling and a production run.
It may be possible to mould shorter sections that attach together, but that has its own issues re structural integrity, electrical performance and bulk.

pat- well, we would probably be willing to buy a lot of them and stock them for use later after sets start wearing out, but there would be 5 used at a time, untill they wear out, but I still don't think we'd be buying enough of them to make it worth it for the provider- and like you said, we're considering just using hydlar in short form (maybe even a few inches, drilled rod maybe) on the ends then g10fr4 in the middle...
demon- thx for the info! I'll get to googling some more...
thanks again guys

"Hydlar Z would also be difficult to extrude in this form. It is unlikely we would be successful. However we do produce rigid Hydlar Z rod which could be machined into tube depending on the diameter and length of tube that you need."
any of you guys mind explaining why it might be so hard to extrude? just due to the material's extreme specs? forgive me for the stupid questions but does this stuff not melt and harden/cool the way so many other materials do? Know where I might find a scientific explanation?
thanks again!

You need a certain viscosity range so it can be pushed through a die, but still retain its shape until it solidifies. There are obviously techniques to assist in this, but they have limits.
