Tervakoski Film

What Tervakoski Film does

Tervakoski Film is a European specialty manufacturer of polypropylene (PP) dielectric films used as the core insulating medium in capacitors. Founded in Finland in 1921 as one of the world's first dielectric film producers, the company has progressively relocated its production base — and in 2010 its headquarters — to Svit, Slovakia, where it now operates as Terichem Tervakoski, a.s., a joint venture between Finland's Ab Rani Plast Oy and Slovakia's Chemosvit, a.s. The group runs a ~260-person plant in Svit (housing base-film production, metallization with aluminium, zinc, alloy, and bi-metal configurations, pattern metallization, and a new 2025 LISIM line) and a ~80-person plant in Lutsk, Ukraine (tenter-frame film and metallization/wrapping film), for roughly 340 employees dedicated exclusively to capacitor film.

The product portfolio spans four families: base films for metallization (ECT, ECTS, RERCT), films for impregnation (RERT), metallized films (TSC, TSX, TSXU, TSY, TSYL, TBX, TSXG), and wrapping films (KXS, ET), plus the differentiated Tervakoski Film ECU ultra-high-temperature (up to 135°C) film made from Stelora™ renewable feedstock for EV power-electronics. The technology base rests on tenter-frame BOPP film production, proprietary Brückner LISIM simultaneous biaxial stretching (the only capacitor-grade LISIM line in the Western Hemisphere and the widest in the world), and full in-house traceability from raw material to finished film. Tervakoski Film ECU underwent nearly 200,000 hours of testing prior to launch.

The company sells B2B under a direct-sales model supported by regional agents in India, China, Brazil, and Turkey, with quote-based pricing, FCA delivery from Svit or Lutsk, 14-day net payment terms, and multi-year contracts. End applications are HVDC and smart-grid power infrastructure, electric vehicles, traction (locomotive/rail), and industrial infrastructure (power-factor correction, DC links, filtering). The customer base — major capacitor manufacturers serving these four verticals — is undisclosed by name, as is revenue. Quality is underpinned by ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, ISCC Plus, RoHS, and REACH compliance, with IATF-compatible processes.

Core offering

Tervakoski Film manufactures high-quality polypropylene (PP) dielectric films used as the core insulating material in capacitors. Its product portfolio covers base films for metallization (ECT, ECTS, RERCT), films for impregnation (RERT), metallized films (TSC, TSX, TSXU, TSY, TSYL, TBX, TSXG), wrapping films (KXS, ET), and the ultra-high-temperature Tervakoski Film ECU line. The films are sold to industrial capacitor manufacturers and OEMs serving power grids, electric vehicles, traction, and industrial infrastructure.

Product overview

Tervakoski Films Group is a global leader in manufacturing high-quality polypropylene (PP) dielectric capacitor films. The company offers a comprehensive portfolio of capacitor film products organized into four main categories: base films for metallization (ECT, ECTS, RERCT), films for impregnation (RERT), metallized films (TSC, TSX, TSXU, TSY, TSYL, TBX, TSXG), and wrapping films (KXS, ET). Additionally, Tervakoski Film ECU represents an innovative ultra-high temperature product line specifically designed for electric vehicle applications. The products are used across four key industries: power grids and smart grids, automotive/electric vehicles, traction (locomotive), and industrial infrastructure. The company operates manufacturing facilities in Svit, Slovakia and Lutsk, Ukraine, with the new LISIM production line being the first of its kind in the western hemisphere for ultra-thin capacitor film production.
