the ez flow is a very soft plastic to begin with.thats why its for the difficult molds and hand pours, When I talked with them they said it also had a lower melting point. I was going to use it for dipping but needed a harder plastic so I went with pourasol. Not as clear as CC plastic but not being able to buy bulk in the CC I went back to pourasol.and have been very happy with it. They are all different, ya just got a get what works for you.
