The introduction of polypropylene polymer brought the massive change in the packaging industry after its inception.

After just three years of research, it became the first choice for the packaging industry and now a multibillion-dollar, world industry. Read the complete story of the emergence of polypropylene.

The invention of polypropylene was accidental, and credit for its invention goes to two scientists, J. Paul Hogan and Robert L. Banks. The researches were engaged by Phillips Petroleum Company to find ways to convert gases into gasoline components.

In the process, both scientists began to study catalyst and how it works. In one of their reaction, they made some changes in their original catalyst and included chromium oxide in it. They were expecting low molecular weight hydrocarbon from it. Then they added propylene with propane carrier through a pipe which was packed by the catalyst. Although they were expecting something else, they got a completely new polymer crystalline, polypropylene. It was a big breakthrough for both of them. From the time, the world got a product that has the multibillion-dollar industry in the present time.
