HARRINGTON INDUSTRIAL PLASTICS LLC

Harrington Industrial Plastics LLC specializes in the design, fabrication, and manufacturing of precision-engineered plastic components and assemblies for government and industrial applications. Leveraging expertise in thermoplastic and thermoset molding technologies, the company delivers high-tolerance parts used in environmental, mechanical, and structural systems where durability, chemical resistance, and dimensional stability are critical. Their technical capabilities include injection molding, extrusion, and secondary finishing processes such as machining, welding, and surface treatment, with an emphasis on meeting stringent material specifications and quality control standards required in defense, aerospace, and infrastructure sectors. The company’s differentiator lies in its ability to produce custom polymer solutions tailored to unique operational environments, particularly in coastal and high-humidity conditions typical of Pacific operations. Award history is not available to confirm specific agency engagements, so no definitive patterns of federal client relationships can be inferred. Similarly, without recent contract data, direct associations with particular government programs or procurement categories cannot be established. The primary NAICS code 326122 indicates a focus on plastic pipe, tube, and profile manufacturing, which in practice translates to the production of extruded and molded plastic components used in fluid handling, electrical conduit, and structural support systems. The company positions itself within the industrial polymer supply chain, serving markets requiring non-metallic alternatives to metal components for corrosion resistance and weight reduction. Harrington Industrial Plastics LLC is a small business structured as a 2K entity, with no government certifications on record. Based in Kapolei, Hawaii, the company maintains a localized operational footprint with potential alignment to Pacific-region defense, transportation, and public works infrastructure needs. Its geographic positioning suggests strategic relevance to U.S. military and civil infrastructure projects in the Indo-Pacific theater, though direct programmatic ties remain unverified by available award data.
