M.S.M. INDUSTRIES, INC.

M.S.M. Industries, Inc. specializes in the manufacturing of high-performance plastic films, sheets, and resin-based materials for demanding industrial and defense applications. Their core expertise lies in producing unlaminated plastic sheeting and custom polymer compounds, often tailored for mechanical, structural, or environmental resilience in mission-critical systems. Technical capabilities include extrusion, calendaring, and formulation of thermoplastic and thermoset materials, with demonstrated experience supplying components for aerospace, maritime, and electronic systems. The company’s precision manufacturing processes ensure tight dimensional tolerances and material consistency, making their products suitable for use in harsh operational environments. Their ability to produce both standard and proprietary polymer formulations distinguishes them as a reliable source for specialized plastic components in defense and industrial supply chains. The contractor maintains a strong and consistent relationship with the Department of Defense, supplying critical plastic and resin components for naval, aviation, and ground systems. Recent awards include plastic sheeting for shipboard assemblies and resin-based parts integrated into communications and propulsion systems, indicating deep integration into defense logistics and equipment sustainment cycles. Their work supports both new procurement and maintenance, repair, and overhaul (MRO) requirements across multiple military branches. Industry focus centers on NAICS 326113 (unlaminated plastic film and sheet manufacturing) and 325211 (plastics material and resin manufacturing), positioning the firm as a niche supplier of engineered polymer products for mechanical and industrial use. They serve defense, marine, and electronics sectors where material purity, thermal stability, and mechanical durability are paramount. While they occasionally support other sectors such as shipbuilding and nonferrous metal casting, their primary market is defined by high-integrity plastic components. M.S.M. Industries, Inc. is a small business based in Riverside, California, operating as a 2L entity with no federal certifications on record. Their geographic presence and manufacturing infrastructure enable responsive production and delivery to U.S. defense and industrial customers, reinforcing their role as a trusted domestic supplier of mission-critical polymer solutions.
