What reinforcements do you use?

Thank you. I'll look into it. 

May I ask what you plan to use it for? Folds on watch straps? If it’s for reinforcing the whole top layer of a watch straps the 0.19mm version work awesome, strap stays soft and nice. But in my opinion not suitable to do it that way with this material for padded straps.

Yes, for watch straps. I currently only make flat straps, and I try to keep them thin, around 2mm max. I came up with a pretty solid feeling structure where the thickness is around that 2mm, and I'm using the 0.19mm Velodon in it, but I still have a couple of spots I'm trying to perfect, and I feel a thinner Velodon might do the trick. One of the problem spots is the fold, you are correct.

What about German Salamander as a stiffener?

Yes, certainly something I will try

Tyvek is a spunbonded polyolefin fabric.  It is extremely tear resistant and resists stretching.  If you have seen the tear-resistant envelopes, you’ve seen Tyvek.  I sell a version used in construction as a water-resistant sheeting.  I can imagine it giving straps reinforcement and resistance to stretching.

That’s the problem here. I need a material with a little bit of stretch (A low elongation value but high tear resistance)

Why? If you make a watch strap with padding. And reinforce the top layer with a fully dimensionally stable reinforcement material. When you fold the strap around your wrist it will force the padding to the lining side of the strap. 
 

When it comes to dimensionally stable strong and thin materials there are a lot of options everything from fiberglass mixed with other synthethic materials. (Specially made for leather goods) And super strong from my tests. But also materials like Composite Dyneema, or a lot of other synthetic reinforcements from companies like Jaeger, Rhenoflex, NST, Luigi Carnevali, TechnoGI and so on.

Then Tyvek can be disregarded because it doesn't stretch easily if at all.
