Factory-direct electrical pressure-sensitive adhesives engineered in dust-free coating facilities. Each grade supports rigorous thermal endurance, high breakdown voltages, and clean peel release.
As wide-bandgap (SiC & GaN) power electronics, electric vehicle powertrains, and 5G/6G RF base stations migrate toward extreme power densities, high temperature electrical insulation tape transitions from a passive consumable into an active, mission-critical thermal management barrier.
With modern EV platforms migrating to 800V and 1200V architectures, traditional insulation films face severe partial discharge erosion. Huayuan's polyimide and glass cloth formulations withstand rigorous electrical stresses exceeding 6.5 kV breakdown potentials without dielectric creep.
Lead-free reflow soldering profiles now sustain peak temperatures reaching 260°C. Our silicone-adhesive polyimide systems ensure zero residue release, extreme shear retention, and anti-static ESD suppression during high-speed pick-and-place automated manufacturing.
Tier-1 electronics OEMs and tier-2 assembly converters are actively qualifying high-reliability Tier-2 replacements for western legacy brands like 3M 69, 3M 5413, and Nitto 903UL. Huayuan provides 100% matched technical datasheets with a 30-45% cost efficiency edge.
Selecting optimal industrial electrical tape requires deep evaluation of carrier film chemistry, adhesive crosslinking, thermal insulation classification (IEC 60085), and solvent resilience.

Our twin factories in Zhuhai and Zhongshan adhere strictly to international auditing standards, providing overseas converters and tier-1 manufacturers with seamless traceability and regulatory peace of mind.
Operating continuous statistical process control (SPC). From raw chemical incoming inspection to automated beta-ray coating thickness monitoring, every jumbo roll maintains identical surface tension and peel consistency.
Selected high temperature insulation lines carry UL Component Recognition (File Category OANZ2). Formulated with non-halogenated flame retardants, they meet stringent UL 94 V-0 and VTM-0 self-extinguishing safety criteria.
SGS audited testing ensures 100% compliance with EU RoHS Directive (EU) 2015/863, REACH SVHC declarations, and Halogen-Free demands for North American, European, and Japanese automotive electronics.
Supported by Huayuan International Technology (Hong Kong), we offer multi-currency settlement (USD, EUR, RMB), DDP delivery, rapid sea freight via Shenzhen/Hong Kong ports, and dedicated emergency air-courier dispatch.
Industrial tapes must endure real-world environmental extremes including thermal cycling, vibration, electrolytic solvents, and chemical degradation.
Prismatic and cylindrical battery cells demand superior inter-cell electrical barrier tapes to prevent thermal runaway propagation. Huayuan flame-retardant Mylar and Kapton polyimide films provide electrolyte immersion resistance and superior puncture tolerance.
Interlayer winding and core strapping in heavy-duty Class H generators utilize our woven glass cloth tape (substitute for 3M 69). It absorbs insulating varnishes completely while retaining tensile loads up to 180 lbs/in during extreme thermal expansions.
Our blue residue-free component holding tape provides high initial tack coupled with effortless single-piece removal without adhesive transfer during industrial baking cycles up to 150°C, ensuring optimal aesthetic and mechanical finishes.
