Marlex - HDPE
Research chemists, Paul Hogan and Robert Bank invented Marlex or HDPE
HDPE (high-density polyethylene) and crystalline polypropylene are both plastic products. In 1951, methods of manufacturing these plastics were invented by research chemists Paul Hogan and Robert Banks of Phillips Petroleum.
MarlexMarlex is Phillips Petroleum's tradename for HDPE. One of the first uses for Marlex was for the famous Wham-O hula hoop and milk jugs.
Paul Hogan and Robert BanksPaul Hogan and Robert Banks began their research work together in 1946. LDPE or low-density polyethylene already existed, however, it was not easy to work with. Paul Hogan and Robert Banks were experimenting with high-octane gasoline when they discovered crystalline polypropylene. The researchers then invented a way to manufacture crystalline polypropylene and HDPE.
HDPEHDPE the abbreviation for high density polyethylene plastic. It can be blow molded and is commonly used to make milk, water jugs, and large plastic soda bottles.
