What SaarGummi does

SaarGummi is a Luxembourg-headquartered global supplier of elastomer sealing and waterproofing systems, organized into three divisions: SG Automotive, SG Construction (marketed under the NovoProof brand), and SG Neo. The company's core technology is EPDM (Ethylene-Propylene-Diene-Kautschuk) rubber compounding combined with extrusion, injection molding, and TPE processing, supported by a proprietary database of more than 17,000 compound formulations accumulated over 70+ years. SG Automotive supplies static and dynamic sealing profiles — door seals, window seals, and body-in-white edge protection — to global automotive OEMs using branded technologies including SealMatic (endless door sealing), SolidLight (lighting-integrated seal), SealTex (textile-reinforced seal), VarioProof (variable sealing proof), and VarioSection (modular cross-sections). SG Construction sells EPDM waterproofing membranes for flat roofs, facades, ponds, and biogas plants, installed via the proprietary ThermoFast hot-air welding and NovoWeld induction welding systems, with FLL, EN 13956, EN 13967, and EN 13363 certifications.

SaarGummi makes money primarily through direct B2B hardware sales of molded and extruded rubber components and EPDM membranes, with a smaller professional-services revenue stream from its DIN EN ISO 17025 accredited Central Lab. Pricing is quote-based and negotiated enterprise-by-enterprise with automotive OEMs and construction industry buyers, with no public price disclosure. The company serves three primary customer segments: Global Automotive OEMs (primary), the Construction Industry (primary), and Industrial Materials customers including footwear compound buyers (secondary). GTM is a direct enterprise field-sales motion executed through regional sales teams co-located with manufacturing sites, supported by dedicated division websites (automotive.saargummi.com, construction.saargummi.com, neo.saargummi.com) and a corporate newsroom rather than channel partners.

SaarGummi is a privately held company owned since 2010/2011 by CQLT (Chongqing Light Textile Industry Holding), a Chinese state-owned conglomerate; the Luxembourg parent CQLT SaarGummi Technologies S.à r.l. coordinates 20+ wholly-owned operating subsidiaries across 14 countries spanning Europe (Germany, Luxembourg, Poland, Czech Republic, Slovakia, France, Spain, Russia), the Americas (USA, Mexico, Brazil), and Asia (India, China, Korea). All business units hold IATF 16949 automotive quality certification, and the group operates under ISO 14001 and ISO 45001 management systems. The leadership team is led by Chairman Huagang Nie with CFO Tomáš Slanina, CMO David Lettin, and COO Ilija Ljubicic at group level.
