Greene Rubber Company

What Greene Rubber Company does

Greene Rubber Company is a privately held U.S. custom elastomer manufacturer founded in 1931 and headquartered in Woburn, Massachusetts, with manufacturing operations in Danielson, Connecticut and Chagrin Falls, Ohio. The company designs, prototypes, and produces precision-molded and fabricated rubber, silicone, and plastic components for mission-critical applications across six primary verticals: aerospace and space systems, defense and military, medical devices, general industrial, electronics and semiconductor, and unmanned systems (UAV). Its core product portfolio spans shock and vibration isolators, rubber molding and over-molding (including rubber-to-metal bonding and liquid silicone rubber for medical devices), EMI shielding and thermal management, O-rings, gaskets and seals, sound dampening products, tapes and adhesives, tubing and assemblies, rubber and plastic extrusions, and liquid adhesives, sealants and coatings.

The company's technology base rests on certified manufacturing processes including liquid injection molding of liquid silicone rubber (LSR/LIM), rubber-to-metal bonding for shock and vibration isolation, EMI shielding for integrated circuit packages, and an engineering design-support function that uses Finite Element Analysis (Cosmos FEA), CAD mockups, and proprietary dynamic analysis software. Greene Rubber holds ISO 9001:2015, AS9100:2016, and ITAR registration, and is a 3M Preferred Converter and Saint-Gobain distributor, enabling it to bundle conversion and distribution of premium adhesive and elastomer materials alongside its own manufactured components.

Greene Rubber generates revenue primarily through custom, quote-based one-time sales of molded and fabricated components to enterprise customers in regulated industries, supplemented by hardware sales of distributed adhesives, sealants, coatings, tapes, and adhesives, and value-added services such as bonding, sub-assembly, managed inventory, and packaging. The company sells through a sales-led go-to-market model featuring direct enterprise sales with nationwide support, inside sales through online quote requests, a frictionless reorder system for repeat customers, engineering consultation channels, and participation in aerospace, medical, defense, and unmanned-systems industry trade shows. The company reports serving over 5,000 customers with 65% of business from repeat orders.

Core offering

Greene Rubber Company designs, prototypes, and manufactures custom molded and fabricated elastomer (rubber, silicone, and related polymer) components for mission-critical applications. Their product portfolio includes shock and vibration isolators, rubber-to-metal bonded parts, EMI shielding and thermal management materials, O-rings/gaskets/seals, sound dampening products, tapes and adhesives, tubing, and extrusions, sold primarily to aerospace, defense, medical device, electronics, industrial, and UAV manufacturers.

Product overview

Greene Rubber Company is a manufacturer of custom molded and fabricated rubber/elastomer components established in 1931, serving mission-critical industries including aerospace, defense, medical devices, electronics, industrial, and unmanned systems. The product portfolio centers on nine core product categories: Shock & Vibration Isolators (including various mount types like All-Attitude, Cup-Style, Avionics, and UAV-specific mounts), Rubber Molding & Over-Molding (including rubber-to-metal bonding and LSR for medical), EMI Shielding & Thermal Management (conductive elastomers and thermal interface materials), O-Rings/Gaskets & Seals (butyl, silicone, nitrile, Teflon materials), Sound Dampening Products (elastomeric foams and tapes), Tapes & Adhesives (3M Preferred Converter), Tubing and Assemblies (plastic and rubber tubing), Rubber & Plastic Extrusions (various profiles), and Liquid Adhesives/Sealants/Coatings. These products serve as precision-engineered sealing, vibration isolation, EMI shielding, and thermal management components for applications where failure carries unacceptable consequences. The company operates manufacturing facilities in Danielson, CT (Molding Division) and Chagrin Falls, OH (Manufacturing Division), with headquarters in Woburn, MA.
