Tim at Apogee once called them "Nasal Strips". While they do look like the Breathe Right Strips, they are actually Jewelry Square Barbell Labels made from Tyvek.
If you've ever shopped for jewelry, you've seen these wrapped around the back of the ring with the size and price written on them.
You can't tear through Tyvek paper making these good for shroud line attachment.
They are sticky backed.
So you can see where the adhesive is, I lightly marked the sticky area with pencil. There is no adhesive in the narrow center area where the shroud line is tied.
One half goes under the hole in the chute corner.
Fold the other half over the top leaving a open loop in the middle.
The open middle loop is where the shroud line is tied on.
This small open loop won't tear! The reinforced Tyvek paper is very strong.
Ahh, didn't know they were made of Tyvek. Thanks for that information. The person(s) at NewWay always seem to go the extra mile with their kits. That's what I love about building them. Recently finished the Cornered, a two engine cluster model. Sweet.
ReplyDeleteHi BAR,
DeleteThey are great kits! It's interesting they include sandpaper and a glue apply stick. The square tubes can be a bit rough, but usually clean up well.
If I'm not mistaken, Tyvek isn't really paper (in the sense that it is not made of cellulose fiber), but a paper-like material made of plastic.
ReplyDeleteHi Naoto,
DeleteI looked it up - "Tyvek is a nonwoven product consisting of spunbond olefin fiber." Who knows? I was told it is the paper you cannot tear. It does work pretty well for parachute attachment.
You've probably already found that white glue or wood glue doesn't stick well to Tyvek, and something like rubber cement gives you better adhesion.
DeleteI like to apply a strip of Tyvek over the leading edges of my foam aeroplanes - works nicely as a reinforcement to make them less resistant being dinged up on impact.
I use Tyvek as a ground cloth for ultralight backpacking. Strong and lightweight; works as a ground cloth, rain tarp and anything in between - and now for rockets :-).
ReplyDeleteHi Scott,
DeleteInteresting. It's probably like many new products, they find more uses for it later on.
I know it's used as a house wrap/moisture barrier behind walls during new house construction. Wonder if it can be used in place of cardstock for shrouds and transitions. Worth exploring. Probably too expensive.
ReplyDeleteHi BAR,
DeleteI just read about that house barrier use. I don't know if it can be used for shrouds and transitions. I tried it once for a shock cord mount and it wouldn't absorb yellow glue very well.
The Semroc Golden Scout I recently built used Tyvek to cover the engine catch hook. It did not hold well using white Elmer's glue. If I had to do it again I would have probably used cardstock or some heavy paper. My Tyvek ended up slightly wrinkled.
