Acrylic sheeting, commonly referred to as plexiglass sheeting, is the most common alternative to traditional glass. 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. Specially designed for marine applications, antiskid HDPE sheeting offers superior durability with the additional benefit of a non-skid surface perfect for high-traffic marine surfaces. Total elongation at failure of some polymers: Tensile modulus or Young's Modulus is the ratio of stress to strain within the elastic region of the stress-strain curve before the yield point. For example, polypropylene has a density of approximately 0.90, whereas PET has a density of approximately 1.40. If youve ever felt this way after reviewing a material data sheet, then this next Impact Plastics Blog series focused on Understanding your Data Sheet is for you.

That value must be known in order to determine the overall weight of said project and whether its other components will be able to support the heft of the plastic component - which is why we've put together this quick and easy guide on the weights of some of our most popular plastics. Friction Engineering I'm Gelson Luz, mechanical engineer, welding specialist and passionate about: I am building this blog to be the best learning blog about engineering! Specific gravity is the ratio of the object's density to the density of water, i.e. Since the density of a fluid varies with temperature, specific gravities must be determined and specified at particular temperatures. Also, it is relatively hard and resistant to impact and can be subjected to temperatures of up to 120 C without being affected.
