I've been using Berg's products for many years now, and I've noticed that all of the samples (which are at least 12 to 15 years old) I own of their polyurethane chains have softened with time, and are very easy to mar and take apart by just digging my nails on them... they almost feel like hardened wax to me ...
I hadn't noticed that before because in time I've had to replace all of the chains in my machines due to normal wear and tear. But it still leaves me thinking about the expected lifespan of any product manufactured with this material.
Is this a normal thing with polyurethane?
