Direct-from-factory precision slitted adhesive solutions engineered for rigorous dielectric holding, solvent resistance, and mechanical tensile stability.
In modern high-efficiency switch-mode power supplies (SMPS) and automotive electrification modules, standard commercial polyester tapes fall victim to dielectric breakdown, adhesive outgassing, and edge fraying under thermal cycling. Huayuan’s Mylar tape series is formulated to overcome extreme mechanical and dielectric stresses.
Utilizing high-crystallinity biaxially oriented polyethylene terephthalate (BOPET) backing films, our Mylar tapes deliver high dielectric barrier protection (typically 5,000V+ at 0.05mm total thickness), preventing breakdown arcing in dense high-voltage magnetic coils.
Coated with cross-linked thermosetting acrylic resins, Huayuan Mylar tapes do not soften, flag, or bleed adhesive when subjected to intense vacuum pressure impregnation (VPI) varnishing, mineral transformer oils, or cleaning solvents.
Engineered for high-speed automated winding machinery. The tape profile features stable elongation ratios that absorb high winding tension without necking down in width, ensuring uniform layer isolation across complex transformer cores.
Direct OEM & ODM production delivering structural cost advantages, rapid formulation iterations, and scalable export capacities from the Greater Bay Area.
Our dual facilities in Nanping Science Park (Zhuhai) and Tanzhou Town (Zhongshan) integrate high-speed multi-stage adhesive synthesis, micro-gravure coating lines, and dust-free slitting workshops to guarantee zero supply bottlenecks.
Close partnerships with upstream PET polymer and specialty acrylic resin manufacturers enable raw material cost stability and custom thickness engineering (from 0.025mm up to 0.1mm) with minimal batch-to-batch variance.
Strategically situated near the major maritime hubs of Hong Kong, Shenzhen, and Guangzhou, our specialized export division processes palletized seafreight, air cargo, and cross-border customs manifests under stringent ISO standards.
Huayuan removes international regulatory barriers through end-to-end documentation, transparent batch testing, and engineering-level assistance.
Every lot shipped meets EU RoHS, REACH, and halogen-free directives. Complete SGS chemical test reports and UL94 VTM-0 / Class B electrical insulation system certifications are furnished per specification.
Our Hong Kong international coordination entity eliminates communication gaps. Receive technical datasheets (TDS), safety documentation (SDS), and custom tooling assessments within 24 hours.
Batch-coded log tracing from coating head through rewinding and packaging guarantees full provenance. We support buyer-directed third-party inspections and factory virtual audits on demand.

How leading Tier-1 electronics manufacturers and tier distributors are evolving their supply criteria in response to next-generation power electronics.
With western brands imposing aggressive pricing premiums, multinational buyers are establishing direct relationships with accredited Chinese production plants to achieve 25–40% bill-of-materials savings without sacrificing dielectric integrity.
The transition toward SiC/GaN fast chargers and EV power inverters demands Mylar tapes with high partial discharge resistance, elevated CTI (Comparative Tracking Index) values, and flame-retardant chemistry that prevents thermal runaways.
Raw jumbo rolls alone no longer fulfill the needs of automated assembly plants. Procurement demand has pivoted to custom die-cut components with pull-tabs and finger-lift liners, designed for robotic pick-and-place electronics manufacturing lines.
Proven across harsh industrial environments and mass electronics assembly lines worldwide.
Inter-layer wrapping, core isolation, and outer banding in switch mode power supplies to maintain safe creepage distances and withstand repetitive high-temperature electrical operational spikes.
Electrolyte-resistant outer insulation and electrode tab anchoring for prismatic and cylindrical battery cells, preventing structural shifting and micro-shorts under aggressive vibrating loads.
Phase-to-phase and slot insulation in sub-fractional horsepower motors. Resists abrasion during automated wire-winding cycles and withstands varnish baking operations up to 130°C.
Ultra-thin profile wire harness wrapping, flexible flat cable (FFC) bonding, and PCB shielding ground reinforcement where minimal z-height tolerance and dielectric isolation are non-negotiable.
Comprehensive adhesive catalog items available for custom master log slicing, OEM converting, and private-label distribution contracts.
