Linden Polyurethane

What Linden Polyurethane does

Linden Polyurethane, formerly Linden Industries and founded in 1985 in Cuyahoga Falls, Ohio, is a U.S.-based specialty manufacturer of custom-engineered polyurethane processing equipment and mix heads serving critical applications where mixture accuracy and reliability are non-negotiable. The company's core technology stack covers the full bi-component polyurethane production chain: high- and low-pressure metering systems with high- and low-throughput configurations, multiple mix head architectures (L-style, straight-style, spray-style, and Quality Craft), bulk storage and blending tanks ranging from 2,000 to 25,000 gallons, pentane-rated machinery for low-global-warming-potential blowing agents, gas nucleation equipment for CO2 and N2 infusion that monitors and adjusts gas content in real time, and spray systems such as the Linden PSM 700 developed jointly with Isotherm AG. Notable engineering characteristics include counter-impingement mixing geometries, ceramic mixing chambers for abrasive materials, self-cleaning precision-machined plungers, and modular mix ratios (1:4 to 4:1) supporting shot sizes down to 3 grams.

The company monetizes primarily through one-time capital equipment sales priced on a custom quotation basis, with a multi-year contract cadence and no publicly disclosed pricing tiers. A secondary recurring revenue tail comes from mix head repair and rebuild services for all OEM makes (including competitors Cannon, Hennecke, Krauss Maffei, and Elastogram), metering pump repair for Rexroth and Rotary Power units, mix head rentals as a bridge during customer repairs, and an ISO 9001 certified 7,000+ sq. ft. polyurethane foam testing lab offering feasibility trials, short-run production testing, and ongoing production evaluation. The go-to-market motion is enterprise field sales with consultative specification, supported by content marketing via the company blog, an email newsletter, and annual presence at Foam Expo (most recently combined Linden/SAIP booth at Foam Expo 2025 in Novi, Michigan).

Linden serves approximately 1,310 customers across 28 countries in verticals including aerospace (Boeing, NASA), military/defense (U.S. Navy, Lockheed Martin), medical (St. Jude's), construction (CAT, Owens Corning, ThermaTru Doors, Wayne Dalton), electronics and appliances (GE, Whirlpool), sports and recreation (Polaris, Top Flite), and automotive (Toyota). In October 2024, Italy-based SAIP Advance Polyurethane Equipment acquired a majority interest, giving Linden access to complementary turnkey product lines (processing molds, presses, carousels, material handling) and a global distribution footprint while retaining CEO Jon Cocco and existing management for continuity. Linden holds ISO 9001 certification, U.S. Navy certified supplier status, and Bosch Rexroth-approved repair facility designation, and reports 11-50 employees.

Core offering

Linden Polyurethane designs, engineers, and manufactures custom polyurethane processing equipment including high- and low-pressure metering systems, mix heads, bulk storage and blending tanks, gas nucleation (CO2 and N2/Dry Air) equipment, Pentane machinery, and spray systems for industrial manufacturers. The company's equipment is built to customer specifications for critical applications in aerospace, military, medical, automotive, building and construction, electronics and appliances, and sports and recreation, supported by an ISO 9001 certified testing lab and 24/7 repair and field services covering Linden and competitor equipment.

Product overview

Linden Polyurethane (formerly Linden Industries) is a U.S.-based manufacturer of custom-engineered polyurethane processing equipment serving critical applications in aerospace, military, medical, automotive, construction, and sporting goods industries. The portfolio consists of core equipment categories: polyurethane metering systems (high and low pressure), spray foam equipment (including PSM 700), bulk storage and blending systems, gas nucleation equipment (CO2 and N2 infusion), pentane machinery, and various mix head styles (L-style, straight-style, spray-style, Quality Craft). The equipment works as an integrated production chain where bulk storage feeds blending systems, which supply metering systems that regulate flow to mix heads for final dispensing. The company also provides comprehensive services including mix head and pump repair, equipment rental, and an ISO 9001 certified testing lab. Following SAIP's 2024 majority acquisition, the portfolio expanded to include turnkey solutions such as processing molds, presses, carousels, and material handling systems.
