This will help make polyvinyl chloride extra dense than polyethylene. The density of different plastics is usually a result of the various atoms which might be connected to the carbon–hydrogen chains. Should they be large atoms for his or her dimension, the plastic has a tendency to be more dense; Should they be gentle for his or her measurement, the plastic has a tendency to be less dense.
It desires additional hull to battle waves that might if not fill it and, by expanding its mass, induce it to submerge.
