No. Particle Board is made of particles. MDF is made of fibers. BIG
difference. You can suck air thru MDF which is why it is used on cnc
router tables. You can plop a 4x8 sheet of goods on the table and
cut it into tons of tiny parts without any special jigs or fixtures.
Can't do this with Particle Board. You can't suck air thru it!
