Polystyrene 1.05 0000005093 00000 n 0000002953 00000 n Contrary to HDPE, LDPE is characterized by low-density molecules, giving this resin a thinner and more flexible design. We don't collect information from our users. First, we have to know that the formula of density is: As formula shown, density is total mass of the object divided by total volume of object, which means: 1 gram per cubic centimetre or 1 kilogram per cubic metre.Density of water is1 gram per cubic centimeter (1 g/cm3), but actually, the exact density of water is not really 1 g/cm3, but rather a bit less (very, very little less) than 1, so we can say thatgenerally the weight and volume of water is the same.What's the meaning of "Specific Gravity"?Specific Gravity means specific value of an object undernormal temperature and pressure. Polycarbonates are commonly used for eye protection in the creation of lenses for sunglasses, sport and safety goggles. Beverage bottles are among the main plastic items that come for PET.
