Engineered to deliver high heat dissipation, mechanical strength, and UL-certified electrical shielding across automated assembly lines.
Kapton MT tape offers 3x the thermal conductivity of standard polyimide films while retaining exceptional dielectric breakdown properties.
Standard polyimide (Kapton HN) demonstrates a thermal conductivity of approximately 0.12 W/m-K. In contrast, Kapton MT incorporates inorganic ceramic micro-fillers uniformly distributed throughout the aromatic polyimide matrix, elevating thermal conductivity to 0.37–0.46 W/m-K. This substantially eliminates hot-spots without sacrificing UL Class H (180°C) or Class N (200°C) thermal indices.
Even with advanced mineral loading, Kapton MT tape maintains dielectric breakdown strengths exceeding 4,000 to 6,000 Volts/mil. It operates as an irreplaceable thin-gauge interface layer in primary transformer windings, EV motor stator slots, and high-frequency GaN/SiC power inverter modules where insulation failure would yield catastrophic short-circuit conditions.
Engineered with proprietary thermal-conductive cross-linked silicone or functional acrylic adhesive systems. Our formulations ensure minimal peel transfer, low outgassing characteristics under hard vacuum environments, and stable adhesion on copper, aluminum, ceramic substrates, and polyolefin separators across dynamic temperature ranges from -40°C to +260°C.
Meeting the surge in electrification demands through vertically integrated coating, slitting, and die-cutting operations.
Global markets frequently encounter 16 to 24-week lead times for Western-branded polyimide tapes. Huayuan addresses this bottleneck via large master roll stocking across our Zhuhai and Zhongshan manufacturing facilities, compressing prototype turnaround to 48 hours and high-volume container shipments to 10-15 business days.
By producing our own adhesives, controlling the precision coating thickness via beta-gauge sensors, and performing in-house rewinding and slitting, Huayuan delivers verified OEM drop-in replacements for industry-standard numbers at an immediate 30% to 45% margin advantage for enterprise converters.
Our converting infrastructure includes cleanroom flatbed and rotary high-speed die-cut machines. We supply Kapton MT in custom slit widths (from 2mm up to 1000mm), multi-layer laminated assemblies with heat sinks, pull tabs, and custom-printed release liners suited for robotic pick-and-place lines.

Validated thermal transfer integration across high-growth manufacturing sectors.
In high-capacity pouch and prismatic cell assemblies, thermal propagation is a prime hazard. Kapton MT tape acts as an inner-cell wrapping barrier between active cell envelopes and cooling plates, conducting excess heat directly to cooling conduits while withstanding puncture forces, expansion stresses, and dielectric field spikes up to 800V DC architectures.
Wide Bandgap (WBG) semiconductors (Gallium Nitride and Silicon Carbide) function under dense thermal loads. Die-cut Kapton MT pads serve as thin, uniform thermal interface insulators beneath MOSFET and IGBT assemblies, eliminating thick thermal pads and air-gap risks while maintaining precise 0.05mm bondline thicknesses.
Operating beyond Earth's atmosphere exposes dielectric materials to deep vacuum, cosmic radiation, and aggressive thermal cycling (-200°C to +200°C). Our Kapton MT tape maintains dimensional stability, resists embrittlement, and meets ASTM E595 Total Mass Loss (TML < 1%) and Collected Volatile Condensable Material (CVCM < 0.1%) limits.
Comprehensive export-grade governance aligning with North American, European, and Asian electronics standards.
Every lot manufactured is 100% compliant with EU RoHS Directive 2011/65/EU and its amendment (EU) 2015/863, alongside REACH (SVHC List) standards. Huayuan provides updated SGS multi-spectrum laboratory test reports per batch, confirming halogen-free and antimony-free compliance for green-label consumer devices.
Huayuan executes an ISO 9001:2015 certified quality cycle starting with raw film polyimide monomer inspection through adhesive cross-linking ovens. Each roll is coded with an individualized laser barcode capturing coating batch, ambient humidity, operator ID, and slit width for full historical tracking.
Operated via Huayuan International Technology (Hong Kong) Co., Ltd. for seamless currency exchange (USD, EUR, GBP) and swift customs clearance. Direct logistics corridors from Shenzhen, Guangzhou, and Hong Kong ports ensure consistent air and sea shipping itineraries to North America, Europe, and Southeast Asia.
Accelerating thermal dielectric performance through nano-scale chemical engineering.
Our R&D team is pioneering the incorporation of two-dimensional Hexagonal Boron Nitride (white graphene) platelets into our polyimide varnish. This next iteration aims to reach thermal conductivities exceeding 1.2 W/m·K while maintaining optical clarity, thin profiles (≤25μm), and superior flexibility.
In step with global carbon footprint reduction targets, Huayuan is standardizing 100% solids UV-curable and hot-melt silicone adhesive formulations. Eliminating volatile aromatic solvents during manufacturing reduces overall product carbon footprints by 38% without compromising high-heat resilience.
Collaborating with university laboratories to embed printed nanoscale thermal and strain sensors directly onto the Kapton MT carrier layer, transforming passive insulation films into active real-time health-monitoring matrices for industrial megawatt battery storage banks.
