I don't think its a chemical. There is a proximity sensor connected to the doors that detects when someone is in range, which triggers the doors to open.

Flourine and Magnesium react to human body temperature via heat sensors above the door. This initiates a reaction that forces the two doors apart.

Chemical? I assumed it was done by a motion senser, motor and gears.
