What Relats does

Relats S.A.U. is a privately held, family-owned Spanish manufacturer of technical textile coating solutions for protective sleeving and safety covers, headquartered in Caldes de Montbui, Barcelona since 1957. The company produces fiberglass and silicone-based sleeving products across three industry verticals — E-Mobility & Automotive (89 products), Industrial & Energy (46 products), and Mass Transport (18 products) — with a unified portfolio spanning the Revitex (silicone-coated fiberglass), Periflex (EMI shielding and mechanical protection), and Impact Protection product lines. Relats' technology centers on proprietary material formulations including ceramicized silicone and silicone foam, engineered to deliver thermal runaway protection up to 1000°C, electrical insulation, fire resistance meeting EN 45545-2 / UL 94 / FMVSS 302 standards, EMI shielding up to 74.8 dB at 300 MHz, and operating temperature ranges of -70°C to +450°C. The newly launched BPM (Battery Protection Materials) portfolio represents a strategic expansion into EV battery pack and stationary energy storage safety applications.

Relats operates a globally distributed manufacturing footprint with five production plants across four continents — Spain (Catalonia), China, Vietnam, Mexico, Morocco, and Romania — plus a sales office opened in Turin, Italy in February 2025 to serve European OEM engineering decision centers. The company holds IATF 16949:2016 automotive quality certification across all manufacturing sites, along with ISO 9001, ISO 14001, and EN 9100 aerospace certifications, enabling it to qualify into automotive and aerospace supply chains. Relats China, founded in 2004 with 13 employees, has grown to 116 professionals serving over 350 clients worldwide under an "in-China for-China" strategy, while the corporate headquarters drives R&D via two CDTI-funded projects totaling €1,301,264 (2022-2024) co-financed by the European Union.

The company generates revenue through direct B2B enterprise sales to OEMs, Tier 1 automotive suppliers, and battery manufacturers, with quote-based pricing and bundled engineering support for material selection, application design, and validation. Long-standing strategic customer relationships — exemplified by the decades-long Leoni partnership recognized with their 2024 Overall Performance Award — anchor the customer base. Distribution relies on direct field sales teams with technical/engineering support rather than channel partners, supported by comprehensive digital catalogs, technical documentation, and a client portal. The company operates Relats S.A.U. as a single-member Spanish corporate entity under the Relats family ownership structure, with CEO & Chairman Pere Relats and Chief Strategy & Innovation Officer Sergio Alcaraz in top leadership roles, and pursues institutional relationships through board membership in CIAC (Catalan Automotive Industry Cluster).
