Back in the pre-internet days, this is the book that we all used to look up materials and find property data sheets. The Plastics Materials Digest: International Plastics Selector.
I have been looking for one of these old books on Ebay for a couple of years now and I finally came across this near perfect copy dated 1988 which happens to be my first year in the industry.
I will be using this book to highlight some of the changes that have happened in our industry since the 1980’s. For instance, I counted 111 grades of material in this book that are classified as TPO. Currently on UL Prospector, there are roughly 900 grades of TPO.
More to come.
