Recycling Soda Bottles Experiments Answered
Test 1: heat gun, "high setting" Plastic Coke bottle SOFTENS + shrinks - at about 250F *
Test 2: Heat gun " low setting** " Plastic coke bottle MELTS enough to make gooey threads , and bubbles - at 450 to 500 F
*according to a cheapy harborfreight laser thermometer. Not sure just how accurate it is in the 250 to 500F range. This device seems to read 5 degrees high at the 100F range.
** ironically, the temp is higher on the "low" setting. When the fan is moving less air, that air is hotter.
One of the tricks, I imagine, might be to fully melt the plastic without burning it.
Suggestions welcome. Further results will follow.
