I am looking for a material that has to be flexible and ability to be transparent. It’s function is similar to that of a watch strap, but watch straps are too brittle IMO as they can be tore after some years of abuse. So I was looking at synthetic rubber and came across silicone rubber. Silicone rubber have better physical characteristics, and can be dyed in almost any color. How about the cost? Is silicone rubber more expensive than synthetic rubber?
