It is 250 times stronger and just as clear as glass. 0000166558 00000 n In recent years, the use of these resins has been controversial: the basis of this controversy is their leaching that, occurring at high temperature, releasesbisphenol A, a compound that is on the list of potential environmental hazardous chemicals. Specific GravityDensity and specific gravity sound quite similar, some even say that they are synonyms; however, they are actually not the same, below we are going to introduce the differences of them.What's the meaning of "Density"?Density ismass or weight of a substance per unit volumeundernormal temperature and pressure. Civil Engineering Definition: Density v.s. Not all plastic is born equal. 0000014066 00000 n 0000004599 00000 n 0000124088 00000 n In the next blog post, we will explain which of these plastic types can be recycled and which not, so stick around! Over 12,000 ASTM standards operate globally, including tests specific to plastics, to help consumers have confidence that the products they purchase will perform as expected. If plastic cannot be identified in the six types above-mentioned, then it will be included in group number 7. Specific gravity of a material can be calculated by following equation: The testing method of SG for plastic systems is ASTM D792 and ISO 1183. SG of plastic is less compared to other materials influence its price; thus all plastic materials are sold on cost per weight basis. 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. Hi!

It comes in two basic forms: rigid and flexible. SPECIFIC GRAVITY- The ratio of the weight of the molded piece as compared to the weight of an equal volume of water ASTM D792. This information can be used to tell whether plastic will float (or sink) if dropped in water (Buoyancy). This changes the ratio for our calculation; it is now 0.945/0.74 or 1.28. Also, it is relatively hard and resistant to impact and can be subjected to temperatures of up to 120 C without being affected. To figure the specific gravity of a substance take the number of pounds per gallon the substance weighs and divide it by 8.
