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. Heres a brief recap of what we have learned so far: We hope this blog post has provided some clarity about the differences among all these plastic types. We don't collect information from our users. Plastics that belong to group number one are made out ofpolyethylene terephthalate or PET. WebThe Specific Gravity - SG- is a dimensionless unit defined as the ratio of density of the material to the density of water at a specified temperature. Despite its many advantages and efforts made by the plastic industry to increase its reusability, PVC is still hardly recyclable and should therefore be avoided, whenever possible. Ethylene-propylene 0.86 0000006688 00000 n 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. From here density and SG are calculated using the following formulas: Specific Gravity = (Weight A / Weight B)Density = (Weight A / Weight B) * 0.9976 g/cm3 , where 0.9976 g/cm3 is equal to the density of distilled water at 23C. Plastics have a really wide specific gravity range depending on its composition. Plastics WebSpecific Gravity (SG) is defined as the ratio of density of the material to the density of water (1 g/cm3) at a specified temperature. Polymers typically have a benchmark density that can offer an approximate value of what the density of a particular material can be expected to be. S g = p s /p h20 S g = Specific Gravity of the 0000019679 00000 n When mixed with other substances, It can be made softer and more flexible and applied to plumbing, wiring, and electrical cable insulation and flooring. 0000126937 00000 n Physicists use 39.2 F (4 C) as the standard, but engineers ordinarily use 60 F. In the International System of Units (SI Units), the density of water is 1.00 g/cm3 at the standard temperature.

The specific gravity of a substance is a comparison of its density to that of water. There are two basic test procedures to determine the density of a material method A, used for testing solid plastics in water, and method B, used for testing solid plastics in a liquid other than water. Specific Gravity of Plastic Laboratories, Specific Gravity of Plastic Blood normally has a specific gravity of ~1.060. 0000156682 00000 n HWM7W=T+[h#E\Zc"YLGr>ZH The purpose was to provide a consistent national system to facilitate recycling of post-consumer plastics." When the plastic that expanded beyond the container is removed we now find that the remaining cube of heated plastic inside the container weighs only 0.933 grams. This may also be referred to as relative density. Hardware, Imperial, Inch Electric Motor Alternators The 7 Different Types of Plastic - Plastics For Change Specific gravity, generally speaking, measures the density of an object as compared to water. Tensile yield strength is the maximum engineering stress in psi (or Pa) at which a permanent non-elastic deformation of the thermoplastic material begins.
