For rigid polyurethane, I've seen 1.05 g/cm3 published on the web, which would be about 65 lb/ft3. For flexible poyurethane foam, it varies with how much air is in the foam.

∙ 16y agoThe density of golfball is less then density of water
Density
Density = mass/volumeMass = (density) x (volume)Volume = mass/density
density = mass/volume If you know density and mass, you can calculate the volume by manipulating the density equation such that volume = mass/density. Example: density = 3.57g/cm3 mass = 2.4g volume = ? volume = mass/density = 2.4g/3.57g/cm3 = 0.67cm3
The formula for calculating density is as follows: density = mass/volume. Simply put, if you divide an object's mass by its volume, you will find its density. Density is the mass of an object per unit volume.
The density of polyurethane is very low, so the mass of the racket is diminished.
Normally a low density Polyurethane (foam) covered in vinyl.
On average, 1 gallon of solidified polyurethane paint can weigh between 10-12 lbs. The weight may vary based on the specific formulation and density of the paint.
Polyurethane can be recycled.
it should
Otto Bayer invented polyurethane.
CPI spray is made of Polyurethane Foam. Polyurethane Foam is made by adding water to polyurethane plastics.
Definitely, I would never buy a body kit if it wasn't made of polyurethane or fiber reinforced polyurethane.
Polyurethane will kill you if you eat it.
no dont be stupid
Epoxy and polyurethane can be mixed. An epoxy and polyurethane coating system is often used in the marine industry to protect against the weather.
The poisson ration of uncompressed polyurethane is 0.5; the poisson ration of polyurethane under compression is 0.39. Reference: "Material behaviour in plane Polyurethane - Polyurethane impact with velocities from 10 to 400 m/sec." Published at J. Phys IV France 7 (1997)
