I have ran sulfur around LSR in small quantities at a couple of plants but never next to each other in long production runs. I have ran them in the same press and I understand the clean out involved. Kind of the same situation as some HCRs. I have a big order coming in and wanted to make sure...

Does anyone have any first hand knowledge of where running a sulfur cured material in the same building as an LSR caused a problem?

A 15F change in room temperature would not change the process. The barrel should be regulated by a thermolator to maintain the barrel temperature that you want. A 15 degree hotter environment that the rubber is stored in could have an affect over a long period of time.

Sorry, no it doesn't.

My guess is bromobutyl. I know this compound use to be used in RC car tires.

Anyone know of a rubber that is resistant to super glue?
