Spartech LLC

Spartech LLC

Spartech LLC is an engineered plastics manufacturer headquartered in Maryland Heights, Missouri, with roots in decades of material science. The company was acquired by its management team and a private investment group in 2022, and in early 2024, Andy Filson was appointed President and CEO, with Kevin Duffy joining as EVP of Sales & Marketing (per the firm, February 2024). The business is privately held, and its founding date is not publicly disclosed. Spartech produces custom sheet, rollstock, and profile extrusions across thermoplastics, acrylics, polycarbonate blends, and anti-static compounds. Its end markets include aerospace (RoyalAero line), healthcare, packaging, and industrial applications. The company sources most raw materials in the United States, and operates multiple facilities — though exact locations are not listed. Its Innovation Center, based at headquarters, collaborates with customers on sustainable product development. No fund structure or third-party capital deployment is reported; Spartech functions as an operating company, not an investment vehicle. Team size is not disclosed. The firm maintains no publicly listed philanthropic entities or adjacent vehicles. In February 2025, Spartech launched the RoyalAero R755 product line, formulated to meet FAR flammability requirements for aerospace interiors (per the firm, February 2025). No AUM, assets, or external investment program is reported. Spartech’s structural differentiator is its vertically integrated material science capability combined with a stated commitment to domestic sourcing — a model that contrasts with many plastics compounders that rely heavily on imported feedstocks. The firm is not a family office or asset manager; it is an industrial manufacturer with a family-office-like ownership structure (private, management-held).
