in function to my great search of elastomers…i need to know what these sandals are made of. they aren’t your typical cheap foam sandals. They are much more flexible and rubbery-like. anyone got any info???
Polyurethane, Rubber and PVC
They are your typical rubbery foam sandal just branded better.
Here’s the link to their super-heavy, super-ugly site: http://www.havaianas.com.br/eng/1024/home.html
They have a part with the history of the sandals so you might want to take a look at that, that is, if you are patient enough for everything to load…
mmm…not sure about that.
I think the havianas outsole is perhaps a blown rubber compound, not PU foam (PU foam is self skinning and would wear out differently/faster).
The toe strap I dont think is PVC, but rather likely rubber, or perhaps a TPR (thermoplastic rubber).
there should be a a comma between polyurethane and rubber in my post…which i just edited.
um, no. I think R is right on this one, the straps are rubber and the sole doesn’t wear like normal cheapo sandals. I have a pair that I’ve worn every summer for 5 years now and they are barely showing signs of wear… best flip-flops I’ve ever had.
Everything’s rubber. It was a “material accident” - can’t find any information on what exactly goes on with their rubber, but that’s it. Rubber that doesn’t make your feet smell, sweat, doesn’t wear off easily, straps that don’t break…
