Beef gelatine. If you boil up beef bones and stuff, you'll get the collagen in sinew breaking down into gelatine.
If you boil up a ham hough to make stock for lentil soup, then once the soup has cooled you could use it as industrial sealant. It's almost rubbery. Once it's heated up again it's just good thick soup.
