Marine Polymers, Inc.

Marine Polymers, Inc., a for-profit manufacturer of specialized polymer tiles and marine components based in Stevensville, Maryland, operates as a prime contractor to the Department of the Navy, supplying engineered rubber and polymer fabricated materials for naval vessel maintenance and shipyard operations. The company competes full-and-open; it holds no SBA set-aside designations across its primary footprint, though scattered small-business set-aside awards appear in the source data.

Marine Polymers' concrete capability set centers on the design and manufacturing of custom polymer tiles in multiple configurations (24x24-inch, 24x36-inch, curved variants, blank tiles, baffle tiles, and sail cusp tiles), SEPA fairing strips, sheets, and related marine polymer components. These products serve as flooring, impact absorption, acoustic, and anti-corrosion materials for Navy ships, submarines, and shore facilities. Representative prime work includes a $5.34 million definitive contract from Naval Supply Systems Command (NAVSUP) awarded September 3, 2025, for 4,000 units of specialized tile (NSN 1H-2090-015737200-ST) with completion scheduled for January 19, 2027; a $6.114 million definitive contract from NAVSUP awarded October 20, 2022, for 24x36-inch tile products with an October 2024 completion date; and a $5.24 million definitive contract from NAVSUP awarded May 7, 2025, for blank 24x36-inch tiles. Each award emphasizes engineering source approval from the Navy's design control activity, reflecting Marine Polymers' unique design capability, manufacturing knowledge, and data rights that the government has determined are not economically available elsewhere.

Customer concentration is acute. Naval Supply Systems Command accounts for 96 awards and $73.1 million (76% of combined potential value) across the visible footprint. Defense Logistics Agency Document Services places two awards totaling $22.8 million (24% of combined potential value), and Naval Sea Systems Command has issued twelve awards valued at $541 thousand. The company has worked with the Secretary of the Navy Office of Naval Research on two awards totaling $15 thousand. The two rankings converge tightly — NAVSUP drives both volume and dollars — signaling a single-customer-dominant business model rooted in Navy polymer component supply.

Marine Polymers holds Indefinite Delivery Contracts with NAVSUP referenced repeatedly across purchase-order awards in the source data; source material indicates ceiling values of $12.9 million and $9.9 million on two separate IDCs, though task-order counts under named IDCs in the structured vehicle block are minimal, suggesting most awards flow through purchase orders rather than formal delivery-order task lines. The company's award velocity has been episodic: three awards in 2022, ten in 2023, seven in 2024, six in 2025, and seven through April 2026. Nine awards valued at $10.3 million reach ultimate completion within the next twenty-four months, representing recompete opportunity.

In its subcontractor role, Marine Polymers supplies polymer components to Electric Boat Corporation on three sub-awards related to submarine construction (SSN 804 and related platforms) dated June 2023, September 2023, and April 2024, though dollar values and scope are not detailed in the source.

Marine Polymers has held SAM registration since 2001 and operates entirely within PSC 2090 (Miscellaneous Ship and Marine Equipment) and PSC 9320 (Rubber Fabricated Materials), with primary NAICS concentration in Ship Building and Repairing, All Other Rubber Product Manufacturing, and related machinery categories. The company's business model is characterized by sole-source or competitive qualification procurements from a single dominant customer (NAVSUP) leveraging specialized engineering capability and established technical data rights — a defensible but narrow customer concentration that ties growth and recompete risk tightly to the Navy's tile and polymer component spending trajectory.
