About Elantas
Elantas High-Performance Electrical Insulation SolutionsAltana
Elantas, a division of the Altana Group since 1904 and headquartered in Wesel, Germany, is the global leader in high-performance electrical insulation materials for the electrical, automotive, and electronics industries. With 1,784 employees across nine manufacturing facilities in Europe, Asia, and South America, Elantas supplies an unmatched portfolio of wire enamels, insulation tapes, flexible films, impregnating resins, casting and potting compounds, and conformal coatings to motor and transformer manufacturers worldwide.
Elantas's wire enamel portfolio covers polyester, polyesterimide, polyimide, and modified resin chemistries optimized for different thermal classes (NEMA 130°C through 220°C / IEC 155–180°C). These enamels are applied to copper and aluminum magnet wire by motor manufacturers and rewound industrial motors to meet stator and rotor insulation requirements across fractional-horsepower to mega-watt scale applications across HVAC, industrial pumps, and electric vehicle drive motors.
The impregnating resins and varnishes division serves motor, generator, and transformer manufacturers requiring vacuum-pressure impregnation (VPI) or trickle impregnation processes to achieve Class F, H, and C insulation ratings (IEC 60085 standard). Casting and potting compounds address high-voltage module protection, transformer winding encapsulation, and moisture-resistant sealing of PCBs and electronic sensors per IEC and UL standards.
Conformal coatings (acrylic, urethane, silicone, and parylene chemistries) protect PCBs, power modules, and sensor assemblies from moisture, dust, thermal cycling, and chemical corrosion in automotive, industrial automation, and outdoor lighting applications. All Elantas materials are formulated to RoHS, REACH, and halogen-free compliance where required by regional environmental regulations.
ChatMRO's AI assistant lets you specify your insulation challenge—wire gauge, thermal class, potting volume, environmental exposure, or regulatory requirement—and instantly retrieves matching Elantas wire enamels, impregnation resins, casting compounds, and coatings from our indexed catalog, eliminating the need to cross-reference technical data sheets or contact multiple distributors.

Frequently asked questions
What wire enamel thermal class should I specify for a NEMA 184T motor rewinding?
NEMA 184T motor frames typically operate at NEMA Class F (155°C) insulation design, requiring polyester or polyesterimide wire enamels meeting IEC 60317 specifications for that thermal class. If the motor serves a critical high-ambient or duty-cycle application, Class H (180°C) polyimide enamel is a common upgrade for added margin; always verify the nameplate thermal class and consult Elantas's UL/IEC certified data sheets to ensure wire gauge and chemical compatibility match.
How do VPI and trickle impregnation differ, and which should I choose?
VPI (vacuum-pressure impregnation) evacuates air from coil cavities under vacuum, then impregnates under pressure, achieving maximum resin penetration and moisture blocking, ideal for critical high-voltage or megawatt-scale motors and generators. Trickle impregnation gravity-flows liquid resin through coils, requiring less capital equipment but offering lower void fill—trickle is common for factory-rewound motors and replacement spools where VPI capability isn't available on-site.
What conformal coating should I use for outdoor industrial sensor PCBs exposed to salt spray?
Parylene or silicone conformal coatings are preferred for salt-air/corrosive-atmosphere outdoor sensors (IEC 60068-2-52 salt-fog testing equivalent); acrylic coatings do not provide sufficient ionic-contamination barrier in those environments. Verify the coating's compliance with UL 746E and the sensor manufacturer's approved-materials list before production application.
Are Elantas casting compounds compatible with modern lithium battery modules?
Elantas offers potting compounds specifically formulated for battery pack thermal management and electrical isolation, with low exotherm (reduced heat generation during cure), non-corrosive formulations to protect aluminum battery housings, and certifications per UL 94 and IEC 60950 safety standards. Consult Elantas's battery-module data sheets to confirm thermal conductivity, coefficient-of-expansion match with battery cell casing, and cure-time compatibility with your assembly line.
Do Elantas wire enamels meet automotive OEM (Original Equipment Manufacturer) requirements?
Yes—Elantas maintains certifications for major automotive OEMs including Ford, GM, Volkswagen, and Tesla, with wire enamels meeting proprietary low-temperature-rise, high-voltage-withstand, and moisture-absorption specifications. OEM-qualified enamels are typically cross-referenced by wire supplier (Southwire, Anixter, etc.), so consult your magnet-wire distributor's product data sheet to confirm Elantas enamel grade and OEM approval.
