Tracing its origins to the 1940s, Polymershapes began as two small plastic and parts businesses. These enterprises, Cadillac Plastics, and Commercial Plastics, expanded over decades, becoming the leading distributors in the plastics industry.

Acquired by General Electric in 2000, they were merged into “GE Polymershapes.” In 2008, GE sold the business to SABIC, a global petrochemicals manufacturer.

Then, in 2016, Polymershapes returned to its roots, becoming an independent entity serving customers globally.

Over the past 70 years, Polymershapes has consistently focused on providing superior service, expanding its expertise and portfolio, and setting new standards in the plastics distribution industry.
