What Interstate Advanced Materials does
Interstate Advanced Materials, founded in 1980 and headquartered in Sacramento, California, is a specialty distributor of high-performance plastics and composite materials serving industrial manufacturers across multiple verticals. Its product portfolio includes engineering thermoplastics such as PEEK (unfilled, glass-filled, and bearing grades) and Delrin acetal sheets, alongside composite materials selected for demanding thermal, mechanical, and chemical environments. The company serves customers in semiconductor manufacturing, food processing, automotive, and general industrial manufacturing, with documented Bay Area, Northern California, and Southeast US coverage.
The company operates through nine physical branch locations functioning as Solution Centers, providing both material distribution and value-added manufacturing services including CNC machining, custom fabrication, cut-to-size, and heat forming. This branch-plus-services model positions Interstate as a technical partner rather than a pure logistics reseller, with engineering-grade material selection guidance embedded in the customer relationship. The company supplements its distribution operations with a published library of technical white papers and machining guides targeting engineers and machinists.
Commercially, Interstate Advanced Materials generates revenue through two streams: hardware sales of plastics and composite materials, and professional services revenue from CNC machining and custom fabrication. Pricing is quote-based and not publicly disclosed, reflecting standard B2B distribution practice. In April 2026, the company was acquired by Curbell Plastics Inc., an Upstate New York-based plastics distributor, integrating Interstate into a combined 31-location national network with 150+ employees joining from Interstate. Key leadership and team members have continued through the transition, and the company now operates as a Curbell Plastics subsidiary.
