The specific gravity of plastic is the ratio of the density of plastic to that of a reference substance (Usually water). 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. 0000125957 00000 n Specific Gravity (SG) is defined as the ratio of Acrylic doesn't have as much impact resistance as polycarbonate; polycarbonate's tensile strength is greater than that of PVC; PVC's heat deflection abilities are lesser than Vivak's; and so on, and so on. Fun fact: because it is VERY resistant to fatigue, PP is usually used for living hinges (the thin piece ofplastic that allows a part of a product to fold or bend from 1 to 180 degrees). 0000134268 00000 n Learn more about our materials and get in touch withour sales team today!

It is calculated by dividing the mass of the material by the volume and is normally expressed in g/cm 3. The density of a plastic sample may change due to change in crystallinity, loss of plasticizers, absorption of solvent, etc. used for pressurized water systems - sprinkler.. highly resistant to acids, bases and many solvents, resistant to a variety of acids and bases, may be damaged by some solvents and chlorinated hydrocarbons, usable for water, gas and drainage systems, similar to PVC - but designed for water up to, resistant to abrasion, acids, bases, solvents and much more. 0000002716 00000 n Engineering Forum PA-12 1.02 Polyvinyl acetate 1.19 Since then, after undergoing some minor variations, the RIC has been recognized as the worldwide standard plastic classification. 0000152962 00000 n 0000014066 00000 n One of the most basic differences between varieties, however, can be found in how much they weigh. 0000124655 00000 n 0000002953 00000 n Used in plastic bags,six-pack rings, various containers, dispensing bottles, and most famously for plastic wraps, is not often recycled through curbside programs.
