We keep hearing all these different temps from the media and OCFA. I am pretty sure they are both using Farenheit and Celsuis interchangably in their remarks and this can be confusing as heck. I just heard a media update state that “50 degrees is the happy place” for MMA. 50°F is the Flash Point of MMA and yes, below 50°F the material is BELOW its FP and thus less dangerous from its flammabiity hazard. As we know that 50°C is well above the DANGER RANGE for MMA.
So there are a number of critical temperatures we need to know regarding MMA and its ability to polymerize.
