Expanded PVC sheet plastic is the ideal material where durable construction materials are needed. 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. ?b0/7>41"FUm'V69mjqQn[pd@,XrKC^k $e-eI]abs6QCoq$Y+4Gb=.bsm?JBny!Q.h38'!xSi{C ,*+R9hHz At Plastics For Change, we are giving second life to discarded plastic numbers 1,2,4, and 5 and re-use them for the creation of various different products while cleaning our oceans! Polybutene 0.91-0.92 The information is provided by the molded piece as compared to the weight of an equal volume of water The specific gravity of a substance is a comparison of its density to that of water. The most widely used member of the vinyl family, PVC is excellent when used for corrosion-resistant tanks, ducts, fume hoods and pipe. 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.
