Expanded PVC sheet plastic is the ideal material where durable construction materials are needed. Mechanical Tolerances Specs As far as its disposal is concerned, HDPEis accepted at mostrecyclingcenters in the world, as it is one of the easiest plastic polymers torecycle. The specimen is weighed first in air (Weight A), and then weighed when immersed in distilled water at 23C (Weight B). 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. Urine normally has a specific gravity between 1.003 and 1.035. Manufacturing Processes ASTM D792 Easy for Beginner: Plastic Material Identification by Buoyancy Test, How to Identify Plastic Materials by Burn Test Accurately, No.98, Ln.
