Perhaps better known by its commercial name Styrofoam its highly inflammable and dangerous as it can leach harmful chemicals, especially when heated (which often happens because, as its found in disposable take-out containers, people oftentimes microwave it to heat up the food inside it). For example, The American Society for Testing and Materials (ASTM), approximately a 30% density reduction from PET to PP and an increased yield on pounds purchased. WebSince the density of a fluid varies with temperature, specific gravities must be determined and specified at particular temperatures. 0000006323 00000 n We carry a large selection of American-made Tamco industrial strength tanks. respect to the website or the information, products, services, or related graphics contained on the website for any purpose. Though that may seem like a simple and not particularly worthwhile distinction, any engineer worth their salt will tell you that weight is of the utmost importance when deciding whether a material is appropriate for a particular project.
