As I mentioned in a recent post, after a number of years of searching, I finally found a copy of the Plastics Materials Digest – International Plastics Selector. Before the internet, when I needed to find a material or look up properties, this is how I did it.
The books contain thousands of property data sheets as well an index that allows you to look up materials by trade name and even physical properties.These books were very good. If you needed a polypropylene with tensile strength over 3600 psi, you could find it in the index and then it would refer you to the page where you could find the full data sheet.
The copy that I found happened to be from 1988, the same year that I started in the industry.
I have had a little time to look through the book now and I have a few observations.
