Title: Tyvek hinges or ?
Post by: Steven Kientz on June 07, 2008, 06:44:31 AM

I saw my wife struggling to open an envelope the other day, was wondering if anyone had tried tyvek for hinges or reinforcment on tail feathers, fuselages?

Tyvek makes exceptional hinges. We've it for years in our pylon racers. There used to be a product on the market called redi hinge. Some of you might remember it. It was machined balsa with a hinge material inside. It was available in two thicknesses, 1/4" and 3/8". The hinge material in this product was Tyvel. We've never had it fail even under the most extreme conditions.

Have you noticed what houses are now wrapped in before the siding is put on? Also the large mailing envelopes (white ones) are made of it.

thanks for the info, the way the economy is going I hate to throw away something that is useful. I find it hard to believe that we had junk mail show up in such an expensive envelope.

Thanks again

Back when we used 5 1/4" and larger diskettes the premium envelopes were made from Tyvek.  The stuff they put on houses is too thick but the old envelopes might work out fine. #^

The envolope and gown Tyvek is softer and I think thinner than the house wrap. The house wrap has like a sizing in it to make it somwhat stiff. The house wrap makes great Kites.
