Developed many technical processes in the plastics industry. Widely known as a prolific author and educator.

Rubin's career in plastics began in 1940 as technical director of the molding plant of Robinson Plastics Corp., Hoboken, NJ (then in New York City). From 1942 to 1945, he was chief shift chemist at Montrose Chemical Co., in charge of producing tri-cresyl phosphate plasticizer for PVC cable for the war effort. From 1945 to 1946, he ran the manufacturing plant of Columbia Plastic Products, which fabricated acrylic products.

In 1946, Rubin joined Robinson Plastic Corporation. In 1967, he purchased the company and became its president. He is responsible for injection molding, designing, engineering, and production. Since 1962, he also has been president and owner of Irvin I. Rubin Plastics Corp., a manufacturer of plastics medical devices and equipment.

His technical contributions to the industry include the development of vacuum metalizing on polystyrene as a commercial process for industrial lamp parts. Also significant was the development of internal carving and coloring of fabricated acrylic parts. In the late 60s he assisted in the production of the first injection molded thoracic drainage system -- a process that is now standard.

In the 60s, Rubin published his first series of technical articles for plastics publications. His first book, Theory and Practice of Injection Molds and Molding, was published in 1972. In 1977, he wrote the chapter on injection molds and molding in Introduction to Polymer Science and Technology. In 1990, he edited the Handbook of Plastics Materials and Technology and wrote the chapter on injection molds and molding in the SPI Plastics Engineering Handbook.

Thousands have benefitted from Rubin's seminars and lectures. He combines practical knowledge of machine, mold, material, and management into an integrated unit that is no longer a "black-box" operation, but a logical process.

Rubin received his BS in chemistry in 1938 at CCNY in New York and earned credits at Brooklyn College towards his Masters. He is a Fellow of the SPE and his activities include president of the New York Section, vice chairman of 1955 ANTEC, chairman of the Publications Committee, and chairman, I.T. Quarnstrom Foundation. He also served as president of the Plastics Molders Guild, consultant to the New York City Board of Education, and as an expert witness in state and federal courts.

He resides in Brooklyn, NY with his wife, Laura. They have two children, Julie Ann and Jesse, and two grandchildren.
