I am looking for a recommendation for the type of rubber to make a square profile O-ring that meets the following criteria
1)The O-ring will be subject to temperatures down to -45ish Celsius (-50ish Fahrenheit) and still remain flexible enough to apply the following pressure.
2)The O-ring will be subject to compression pressure of 101.3 kPa, 851.8 kg total (14.696psi, 1878lb total)
3)The O-ring needs to be made of food safe material.
4)Material is such that it could be mixed and cast in a mold in a home workshop environment.
The dimensions of the O-ring are as follows
A = 318mm
B = 324mm
C = 2.5mm
Any recommendations would be greatly appreciated.
