To figure the specific gravity of a substance take the number of pounds per gallon the substance weighs and divide it by 8. WebSpecific gravity is a measure of the ratio of mass of a given volume of material at 23C to the same volume of deionized water. 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). 0000157774 00000 n Since then, after undergoing some minor variations, the RIC has been recognized as the worldwide standard plastic classification.

Vivak Sheet has become a staple in the point-of-purchase industry due to its economic advantages compared to polycarbonate and superior impact strength over acrylic. or in connection with, the use of this information. Because its made with long unbranched polymer chains its much stronger and thicker than PET. 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. Power Transmission Tech. As usual, remember to opt for reusable alternatives to plastic, to avoid purchasing the dangerous types and recycle as much as possible the types of plastic that you can!
