Direct factory production from Zhuhai Huayuan Electronics Co., Ltd. Class-leading dielectric insulation, high mechanical tensile retention, and zero-residue adhesive transfer engineered for global converters and OEMs.
Understanding molecular orientation, thermal stabilization, and adhesive polymer cross-linking that empower modern BOPET (biaxially-oriented polyethylene terephthalate) films to excel in demanding electronic environments.
High-performance polyester (PET/Mylar) relies on controlled biaxial stretching and thermal setting at temperatures upwards of 220°C. This locks the semi-crystalline polymeric morphology, mitigating anisotropic shrinkage to under 0.5% at 150°C. The resulting films offer exceptional dimensional stability, puncture resistance, and tensile modulus under continuous thermal loading.
Carrier performance is only as capable as the pressure-sensitive adhesive (PSA) coating. China’s premier tape coaters formulate solvent-based pure acrylics, thermosetting rubber systems, and organosilicone polymers. Silicone PSAs deliver continuous 180°C to 200°C resistance with zero ghosting or residue on bare metals, while acrylics yield superior dielectric breakdown and solvent resistance.
While traditional polyimide (Kapton) films command premium pricing for extreme Class H/260°C applications, engineered high-temperature polyesters now satisfy more than 75% of industrial electrical insulation applications at a dramatically lower total cost of ownership (TCO). Optimized flame-retardant Mylar tapes meet UL 510 flammability criteria with zero toxic halogen emissions.

In high-density motor windings and power transformers, partial discharge and pinhole dielectric punch-through lead to catastrophic short circuits. Huayuan’s high-temperature polyester films undergo continuous optical pinhole detection and 100% spark testing, guaranteeing zero dielectric breakdown flaws down to 25-micron thin film gauges.
During automated dipping and vacuum pressure impregnation (VPI) of transformers, solvent immersion and baking varnishes degrade substandard adhesive bonds. Huayuan’s thermosetting acrylic formulations reactively cross-link during the initial heating cycle, increasing holding power by over 300% and completely resisting toluene, xylene, and Freon exposure.
Lithium-ion pouch and prismatic cells subject tapes to harsh cyclic organic solvents, such as dimethyl carbonate (DMC) and ethyl methyl carbonate (EMC) mixed with LiPF6 salt. Huayuan’s battery-grade high-temperature polyester films maintain zero swelling, zero adhesive elution, and continuous dielectric insulation across 1,000+ charge cycles.
From new energy electric vehicles to precision 5G telecommunications, Huayuan delivers verified manufacturing solutions customized to rigorous international specifications.
High-temperature polyester tapes serve as primary dielectric inter-cell wraps, busbar insulation barriers, and edge protection in lithium-ion batteries. Our flame-retardant green and blue PET tapes prevent arcing, resist electrolyte penetration, and provide thermal runaway insulation barriers within high-voltage battery enclosures.
For high-frequency switch-mode power supplies (SMPS) and dry-type distribution transformers, Huayuan Mylar tape acts as outer wrap, inter-layer coil insulation, and margin tape. It ensures compliant creepage and clearance distances, fulfilling UL 1446 electrical insulation system (EIS) thermal endurance requirements.
In electro-static powder coating, e-coating, and wave soldering masking, our green polyester silicone tapes safeguard sensitive connectors, gold fingers, and threaded holes. The specially formulated cross-linked silicone adhesive cleanly releases at 200°C without baking residue or silicone oil transfer.
Combining ultra-thin optical-grade PET carriers with conductive fabrics and metal foils, we produce tailored grounding and EMI shielding tapes. These suppress high-frequency electromagnetic interference in 5G antenna arrays, camera modules, and OLED/LCD backplane assemblies.

Micro-defects and particulate contamination ruin dielectric integrity in high-voltage environments. Our multi-head continuous coating and drying lines operate in enclosed, pressurized cleanroom environments. Automated continuous laser calipers scan web thickness across 1,300mm widths, ensuring adhesive coating consistency within ±1.0 micron tolerance.
Full product lines maintain annual testing by SGS for EU RoHS Directive (EU) 2015/863, REACH (SVHC 240+ substances), and Halogen-Free compliance under IEC 61249-2-21 standards. Key electrical insulation grades are certified under UL 510 (Category OANZ2) for flammability resistance, with complete full-disclosure IMDS reporting for automotive tier-1 supply chains.
Beyond master logs and slitted rolls (custom widths down to 2mm), Huayuan operates rotary die-cutting, flatbed laser blanking, and multi-layer laminating equipment. We supply kiss-cut components, pull-tab liners, and complex stamped shapes packaged in anti-static reels, ready for automated pick-and-place surface mount assembly lines.
Advancing material science to meet the demands of higher operating voltages, ultra-fast charging thermal dissipation, and circular economy sustainability.
Traditional polyesters act as thermal insulators (0.15–0.2 W/m·K). Huayuan’s advanced lab is formulating ceramic nanoparticle-doped (AlN, BN) PET matrices that elevate through-plane thermal conductivity beyond 1.2 W/m·K while maintaining breakdown voltages above 5 kV. This eliminates heat-trapping in dense automotive motor stators and power inverters.
Addressing strict global VOC emissions and energy consumption standards, our Zhongshan facility is expanding electron-beam (EB) and 100% solid UV-curable acrylic adhesive systems. This completely eliminates solvent evaporation ovens, reduces carbon footprints by 42%, and prevents solvent retention issues in sealed battery cells.
As wearable tech and foldable electronics demand microscopic form factors, Huayuan is standardizing 12-micron and 9-micron ultra-thin polyester carriers coated with 5-micron nano-acrylic films. These ultra-low profile configurations deliver high shear strength, low outgassing, and tight bend radiuses without delaminating under repeated mechanical stress.
In-depth technical answers addressing resin selection, adhesive cross-linking, qualification protocols, and global distribution logistics.
PET Mylar tape is engineered for Class B (130°C) and Class F (155°C) environments, whereas Polyimide extends to Class H (180°C to 260°C). For applications that operate below 150°C—such as the majority of consumer electronics, switchgear, and battery packaging—high-temperature polyester offers identical dielectric strength (5 kV+) and superior tear/puncture resistance at a 50% to 70% cost reduction compared to polyimide alternatives.
Ghosting occurs when under-cured adhesive polymers split during thermal cycling. Huayuan utilizes high-purity organosilicone adhesives formulated with tailored platinum-cured crosslinking agents. When baked at 200°C for up to 30 minutes on anodized aluminum or steel, the cohesive strength of the crosslinked silicone remains higher than its surface tack, ensuring crisp lines and 100% clean peel without solvent cleaning.
Yes. Selected Huayuan high-temperature polyester formulations incorporate halogen-free flame-retardant chemistry that qualifies under UL 510 (flammability category OANZ2). These tapes self-extinguish within seconds of flame removal, release zero corrosive halogens during combustion, and maintain strict compliance with IEC 60454 and EU RoHS directives.
Huayuan provides rapid prototyping services. Standard slitting widths (2mm to 1280mm) ship within 48 hours. Custom rotary die-cut parts with specific release liner liners or pull-tabs typically take 3 to 5 business days for tooling fabrication and sample submission. We supply full Technical Data Sheets (TDS), Certificates of Analysis (CoA), and sample rolls free of charge for approved industrial qualification.
Huayuan operates an ISO 9001 certified quality system dating back to 2013. We enforce strict multi-stage testing: incoming film corona surface tension testing, continuous online infrared coating weight monitoring, and post-curing adhesion verification (180° peel test per ASTM D3330, shear holding per ASTM D3654, and unwind force per PSTC-8). Every master log roll receives an individual tracking barcode linked to permanent ERP batch records.
Our primary manufacturing plants are strategically situated in the Pearl River Delta: our headquarters in Nanping Science & Technology Park, Zhuhai, and our specialized production facility in Tanzhou Town, Zhongshan. International trade, currency settlements, and export customs handling are managed via Huayuan International Technology (Hong Kong) Co., Ltd., ensuring seamless ocean container and air freight transit to North America, Europe, and Southeast Asia.
