Established in 2007, Zhuhai Huayuan Electronics Co., Ltd. has grown to become an authoritative domestic and global entity in the synthesis of pressure-sensitive adhesive (PSA) systems, specialty film coating, and tight-tolerance rotary die-cutting. Located across modern facilities in the Nanping Science & Technology Industrial Park (Zhuhai) and the expanded 2025 manufacturing plant in Tanzhou Town (Zhongshan), our combined infrastructure addresses demanding operational parameters across high-temperature electrical insulation and high-tack structural fastening.
Coupled with Huayuan International Technology (Hong Kong) Co., Ltd. (founded in 2014) to manage global currency logistics, multi-port dispatch, and seamless international contract support, Huayuan delivers an unbroken chain of custody from chemical compounding to overseas ports. We operate cleanroom coating lines (ISO Class 7 and Class 8 standards) alongside automated optical inspection (AOI) web slitters to ensure our industrial double-sided and electrical insulation tapes exhibit zero pinholes, stable release forces, and microscopic caliper consistency.
Our quality management protocols have maintained unbroken ISO 9001 certification since 2013. Every master roll batch is traceable down to base-monomer lot numbers and coating line telemetry.
Products comply rigorously with EU RoHS 2011/65/EU and REACH (EC 1907/2006) SVHC thresholds, while selected electrical insulation lines achieve UL 510 Recognized Component Status under File Category OANZ2. Independent batch verifications conducted via SGS, Intertek, and CQC validate dielectric breakdown resistance, non-halogen flame retardancy, and low-VOC outgassing profiles.
A structural shift toward Tier-1 alternative sourcing, supply-chain regionalization, and high-performance viscoelastic bonding chemistry.
Global manufacturing operations have encountered persistent inflationary pressures, single-source allocation risks, and lead-time volatility for legacy brand adhesives. Engineering and procurement teams actively qualify domestic and international drop-in equivalents that match the physical, dielectric, and rheological performance of 3M 69, Kapton 5413, or Nitto 5000NS. By partnering directly with our primary polymer synthesis plants in China, OEMs reduce cost baselines by 25–45% while stabilizing production schedules through our multi-ton continuous manufacturing pipelines.
Modern industrial assembly favors closed-cell structural acrylic foam (VHB) and modified acrylic carriers over traditional mechanical fasteners (screws, rivets, welds) and liquid adhesives. Mechanical fasteners introduce stress concentration points, invite galvanic corrosion, and demand hole-drilling operations that degrade substrate integrity. Our structural double-sided acrylic foam tapes distribute dynamic mechanical loads evenly across the joint area, absorb continuous vibration, seal out moisture, and accommodate dissimilar thermal expansion coefficients (CTE mismatch) between metals and composites.
Regulatory regimes across Europe (REACH, RoHS), North America (CARB, US EPA), and East Asia are aggressively capping VOC thresholds within enclosed automotive cabins and consumer electronic devices. Industrial tapes manufactured with archaic solvent-based adhesives risk solvent retention and chronic outgassing. Huayuan’s continuous investment in advanced drying ovens, emulsion-based acrylic technology, and hot-melt silicone formulations ensures ultra-low VOC emissions and total absence of banned phthalates, lead, and polybrominated biphenyls (PBB/PBDE).
Customizing adhesive chemistry, dielectric backings, and release force dynamics to satisfy extreme mechanical, thermal, and electrical environments.
Electrification architectures demand robust dielectric boundaries and thermal management. Our Amber Polyimide Film (PI) Tape and PET High-Temperature Silicone Tapes serve as critical cell-wrapping, busbar isolation, and tab-insulation barriers for prismatic, cylindrical (2170/4680), and pouch battery configurations. These solutions withstand intense organic electrolyte exposure (such as DMC, EC, and LiPF6 salts) without adhesive leaching or delamination, functioning reliably in continuous operations up to 260°C.
During surface mount technology (SMT) reflow and molten wave soldering, gold edge fingers, connectors, and sensitive IC packages require temporary thermal and chemical masking. Our HY200 Polyimide Thermal Masking Series features ultra-purified thermosetting cross-linked silicone adhesives that release cleanly after high-temperature reflow cycles (260°C peak for 30–60 seconds). Crucially, the tape leaves zero adhesive residue and avoids corrosive ionic contaminants, eliminating the need for post-soldering solvent baths.
High-voltage electromagnetic machinery mandates Class B (130°C), Class F (155°C), and Class H (180°C) electrical insulation. Huayuan's Glass Cloth Tape (Substitutes for 3M 69) and Polyester Mylar Insulation Tapes deliver superior tensile reinforcement, high mechanical puncture resistance, and outstanding dielectric breakdown voltages exceeding 5.5 kV. Designed to endure harsh solvent-based varnish impregnations and continuous thermal cycling, they protect motor stator coils and dry-type transformers against inter-turn dielectric breakdown.
5G communication arrays, microwave antennae, and dense consumer electronics suffer from severe internal high-frequency electromagnetic interference. Our Copper Foil EMI Shielding Tape incorporates high-purity electrodeposited copper foil (18μm–50μm) coated with conductive nickel-plated acrylic pressure-sensitive adhesive. This composite structure establishes a path of negligible electrical resistance (contact resistance < 0.05 Ω/sq), effectively shunting electrostatic buildup and offering over 80 dB of attenuation across 10 MHz to 3 GHz.

Challenge: An international EV battery client experienced internal cell shorts caused by burred aluminum casing edges lacerating standard PET wrap films during robotic module drop-in assembly. Additionally, aggressive cyclic electrolyte solvent vapor caused typical acrylic glue layers to dissolve.
Engineered Solution: Huayuan supplied a customized 0.06mm high-tensile Polyimide Carrier coated with a proprietary cross-linked silicone system. The PI carrier provided a puncture puncture-puncture resistance above 180N and maintained dielectric insulation (>6kV). The silicone chemistry exhibited total chemical inertness when immersed in dimethyl carbonate (DMC) electrolyte at 60°C for 500 hours, eliminating failure risks entirely.
Challenge: Heavy rail locomotive traction motors run at internal copper coil temperatures exceeding 175°C. Traditional woven glass tape wraps experienced brittle fiber cracking and delamination during vacuum pressure impregnation (VPI) with aromatic solvent varnishes.
Engineered Solution: Huayuan deployed our High-Performance Glass Cloth Tape (Sub. for 3M 69). Utilizing high-density, alkali-free yarn combined with an un-catalyzed thermosetting silicone adhesive, the tape forms a semi-cure state upon application. When baked at 200°C for 2 hours during post-VPI curing, the adhesive crosslinks permanently, yielding an ultra-dense insulation composite that resists thermal degradation, abrasions, and mechanical vibratory fatigue for over 20,000 operational hours.
Challenge: An automotive OEM required structural fixation for exterior polycarbonate B-pillar appliques to stamped steel frames without unsightly mechanical clips. The bond needed to survive thermal expansion mismatches between plastics and steel across -40°C Arctic conditions to +85°C high-humidity tropical sun exposure.
Engineered Solution: We developed a customized 0.8mm Viscoelastic Closed-Cell VHB Acrylic Foam Tape die-cut to the exact geometry of the applique. The internal foam matrix flows viscously to wet out 100% of microscopic surface peaks on both substrates, compensating for thermal expansion differential while functioning as a continuous environmental seal against water, road salts, and car-wash detergents.
