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.
The 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.
Yes, polyurethane is paintable.
it should
Otto Bayer invented polyurethane.
Yes, water-based polyurethane can be applied over oil-based polyurethane after proper preparation and sanding.
Yes, you can apply polyurethane over old polyurethane when refinishing furniture. It is important to properly prepare the surface by sanding and cleaning it before applying the new coat of polyurethane for best results.
No, it is not recommended to apply oil-based polyurethane over water-based polyurethane as they are not compatible and may not adhere properly. It is best to stick with the same type of polyurethane for a consistent and durable finish.

Yes, polyurethane is typically oil-based.
