Acrylic sheeting, commonly referred to as plexiglass sheeting, is the most common alternative to traditional glass. Plastic (CR-39) and Crown Glass are considered base index with indices of 1.498 and 1.52 respectively. 0000151915 00000 n Hydraulics Pneumatics It is 250 times stronger and just as clear as glass. Plastics The purpose was to provide a consistent national system to facilitate recycling of post-consumer plastics." The tests for density and SG are particularly significant in the custom sheet industry because plastic sheet is sold on a cost per pound basis. 0000172297 00000 n SPECIFIC GRAVITY- for Plastics Material - alfamould.co.in Moreover, the decomposition of BPA in landfills does not occur meaning that this chemical will be persistent in the ground and will eventually find its way into water bodies contributing to aquatic pollution. SPECIFIC GRAVITY- The ratio of the weight of the molded piece as compared to the weight of an equal volume of water ASTM D792. And The SI unit is Kg/m3. Polyethylene terephtalate 1.34-1.39 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. 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). Plastics that belong to group number one are made out ofpolyethylene terephthalate or PET. Description: This 3/8" OD x .062" Wall Yellow Polyethylene Tubing has a working pressure of 120 PSI @ 72F. Water's weight is one gram per cubic centimeter - a material with, for example, 1.5 specific density would then weigh 1.5 grams per cubic centimeter. Polysulphone 1.24 0000014066 00000 n WebThough some manufacturers use grams per cubic centimeter to indicate the weight of their products, others merely provide the specific gravity of their material. The solid wood density may be determined using the green volume, 0000173991 00000 n ph20 = density of water, standarized at temperature 4C (kg/m3), (Samples may vary, and these figures are approximate.

Machine Design Apps The specimen is weighed first in air (Weight A), and then weighed when immersed in distilled water at 23C (Weight B). WebSpecific Gravity Information. Therefore, the specific gravity (which is dimensionless) for a liquid has the same numerical value as its density in units of g/cm3. Polystyrene 1.05 Yield point is the first point where the specimen yields, where the specimen's cross-sectional area begins to contract significantly, or where the strain can increase without increase in the stress.
