Plastics do not all behave the same as their composition and additive packages vary. Some have densities greater than water and would sink, others have densities less than water an float. many of the commonly encountered plastics (polyethylene,, polypropylene, etc.) fall into this latter classification. Higher density plastics include Silicones with densities ranging from 1.68 - 2.00 g/cm3
