Heavy Duty Shrink Wrap for large Battery packs? 400+ MM?

xylene23nyc · Nov 25, 2022

I was wondering if anyone knew of a source for heavy duty rubber-like Battery pack Shrink wrap? 400MM or larger in size?

Luna seems to offer a sold out "Shrink Wrap Tube Matte Black Rubber" in 200mm size but I'm looking for 4-500MM+

Thanks in advance.

I used PVC heat shrink tubing wrap for battery packs. Less rubbery than you might want. But I believe you can find it up to 625mm on Ali or Ebay

Thanks for the response. I already have some of the usual thin PVC 400 mm from Ali or Amazon but was hoping I would be able to find the more rubber like material for better shock absorption.

I haven't been able to find a larger size but Incase anyone else was in need I did find a link to 290mm tube here :

I haven't purchased any so can't verify quality. If anyone can find a 400mm or larger tube source that ships to USA please let me know

Thanks

IIRC the rubberier stuff is called Polyolefin (and is usually stated to be crosslinked). It can come with an adhesive lining, or not. There's also a neoprene version.

I don't think they go up to your size but there's a few types here

I got 820mm ( 32") and I sell it for 10$ a foot. 410mm per side, ( 16 inch).

Large ones too, if they're divided into smaller pieces first. I mean, since you brought it up...

It's good stuff, but they ship only via fedex, so it's quite expensive to buy. I bought 194mm in a 4 foot roll. Probably about $4-5 a foot with shipping.

390 mm (max) of the tough rubber shrink stuff here - https://www.ebay.com/itm/283885096664

I get my polyolefin heat shrink from electronics suppliers. It's sold by diameter, so you have to do some math. This one is the equivalent of 447 mm.
