How much does Polyethylene weigh per cubic foot?

Answer 1

The density of polypropylene depends on whether it is crystalline or amorphous. I'll give both numbers:
Amorphous: 0.85 g/cm3
Crystalline: 0.95 g/cm3

1 cm3 = 3.53147 x 10-5 cubic feet
or
1 foot3 = 28316.847 cm3

So 1 ft3 of polypropylene weighs 24,069.32 g and 26,901.00 g for amorphous and crystalline respectively.

That's also equal to 24.069 kg or 26.901 kg

1 kg = 2.204622 pounds

So 1 ft3 of amorphous polypropylene weighs: 53.064 lbs
and 1 ft3 of crystalline polypropylene weighs: 59.307 lbs

Answer 2

I happen to be an expert on polyethylene and it weighs 12 lbs per cubic foot.
