Heat forming H-45


Recommended Posts

Bake at 225 F for 5-7 minutes, form.


Picture shows a quarter for reference, and my female mold (marble mortar), the final part made from a scrap of 3/8" H-45. Also attached is a Divinycell product PDF.


Application might include pre-forming foam for Cozy-Girl strakes, radomes, nose cones, ...

I have found that the larger the foam piece is tha longer the dwell time before you try to form it. The bottom of my project was done by heating a flat sheet of PVC foam inside of a female mold inside a vacuum bag inside of an oven set to 250 degrees F. I let it sit at 250 and then pulled vacuum.
