What Interstate Specialty Products does

Interstate Specialty Products (ISP) is a privately held, U.S.-based custom die cutting and material converting manufacturer founded in 1963 and headquartered at 55 Gilmore Drive, Sutton, Massachusetts. The company specializes in converting non-metallic materials into precision die-cut components including gaskets, seals, filters, vents, wicks, washers, and thermal management products, serving OEMs across medical and scientific, data center, filtration, electronics, and industrial verticals. Production is concentrated at the single Sutton facility using precision die cutting, digital knife cutting, rotary die cutting, slitting and laminating, and cleanroom manufacturing capabilities.

ISP holds ISO 9001:2015 and ISO 13485:2016 certifications (both valid 2023-2026), with the medical device certification noted as rare within the die cutting industry. The company maintains preferred converter status with Porex and direct material partnerships with W.L. Gore, Rogers Corporation, Henkel, DuPont, FLEXcon, Garlock, Polymer Science, 3M, Parker, Saint Gobain, SABIC, and others, enabling it to convert porous polymers, PTFE membranes, EMI/RFI shielding materials, microcellular urethanes, polyimide films, and a wide range of elastomers.

The business operates on a direct sales model via phone (800-984-1811), email ([email protected]), and a website-based quote request process, with pricing generated per project based on specifications, materials, quantities, and complexity. Quotes are typically returned within one business day. Revenue is generated from custom contract manufacturing and material conversion services rather than from any software, subscription, or licensing offering. Geographic scope is North America only, served from the single Sutton facility, with no disclosed subsidiaries, M&A activity, or external funding.
