Hello -
I have a need for an elastomer that performs reasonably well up to 150% elongation with little to know hysteresis - either in single loading or repeated stretching. We have tested lots of materials and so far, thermo-set polyurathanes perform the best. We have been searching for a TPU...
Ball valves could accomplish what you want - although the temperature/pressure (572 F, 508 psi) puts this in a fairly high class valve. I assume by dead volume you mean the volume around the sealing device which is encapsulated when the valve is closed? If so - then that is where a ball valve...
We were looking for the same info all summer - we came to find out that due to the more "recent" nature of most elastomer developments and the widely varied ways casting and molding houses do their work - there are generally not too many curves out there. We ended up building our own...
