I was wrong about MDF...

A video on YouTube. In DIY & Home Repair, a Krater category.

Summary by Krater

The creator tests MDF versus plywood and radiata pine across ten different types of stress tests, including moisture absorption, deflection under load, heat resistance, and structural failure under heavy weight.

From the video

Answers: Is MDF better or worse than plywood for woodworking projects?

MDF vs plywood comparison
Wood moisture absorption testing
Wood deflection under load testing

Structural load testing on wood shelves

What it concludes

MDF swells significantly more than plywood and radiata pine when exposed to moisture.
MDF with hardwood edge banding performs significantly better under load than standard MDF or radiata pine.
Exposing MDF to direct heat causes immediate and pronounced discoloration and smoke.
