Does particleboard float?
Yes
650 kg/m³ against water's 1,000
Particleboard floats. At 650 kg/m³ it is 1.54 times less dense than water, so about 65% of it sits below the surface and the rest above.
Why
Floating is decided by density alone — mass divided by volume — compared against the fluid. Weight has nothing to do with it directly: a 200-tonne ship floats and a 2-gram pebble sinks, because the ship encloses enough air to bring its average density below that of water. That is also the only reason a steel hull works.

Common questions
- Does particleboard float in water?
- Yes — at 650 kg/m³ it is less dense than water.
- Does weight decide whether something floats?
- No, density does. A 200-tonne ship floats and a small pebble sinks, because the ship encloses enough air to bring its average density below water.
