Explore our factory-engineered adhesive solutions tailored for reflow soldering masking, semiconductor packaging, EV battery cell bundling, and Class H electrical insulation.
Industrial high-temperature double-sided tapes demand precise molecular cohesion, minimal outgassing, and sustained peel strength under extreme thermal cycles (ranging from -40°C to +260°C continuous). At Zhuhai Huayuan Electronics Co., Ltd. (operating since 2007), we formulate proprietary cross-linked polysiloxane and high-$T_g$ acrylic polymers on precision multi-layer carriers.
Formulated with aromatic heterocyclic backbones, our double-sided polyimide tapes exhibit zero glass transition up to 300°C. Symmetrical silicone or acrylic coatings ensure ultra-low ionic impurity, zero charring, and zero residual transfer during reflow ovens and solder immersion.
Engineered through closed-cell acrylic micro-cavities, our industrial VHB foam cores offer dynamic stress relaxation and energy dissipation. Replaces welding and mechanical riveting in curtain walls, EV battery busbars, and commercial automotive panel laminations.
Direct substitute for 3M 69 series. Incorporates high-density alkali-free electrical woven fiberglass bonded with thermosetting silicone adhesives. Features superior puncture resistance, Class H (180°C) electrical insulation, and high chemical stability against varnishes.

Modern electronic assemblies and industrial hardware systems face heightened thermal dissipation challenges and stringent miniaturization constraints. Our tapes serve critical functions across five specialized sectors:
Thermal-conductive and flame-retardant double-sided polyimide and acrylic tapes secure prismatic cells, insulated busbars, and aerogel insulation blankets within high-voltage EV packs, preventing cell-to-cell thermal runaway and mechanical shifting.
Guarantees precision boundary masking during wave soldering and hot air solder leveling (HASL). Withstands reflow peak temperatures up to 280°C without curling, edge lifting, adhesive residue transfer, or halogen outgassing.
Our Class H glass cloth and polyester Mylar tapes deliver phase-to-phase and inter-layer coil insulation in compact inverters, dry-type transformers, and traction motors. Resistant to Freon, synthetic transformer oils, and potting resins.
Copper foil and conductive fabric double-sided tapes bridge low-resistance ground connections across RF enclosures. Certified for low thermal vacuum outgassing (CVCM < 0.1%, TML < 1.0%), safeguarding sensitive optical sensors and satellite communications.
High-strength VHB structural tapes distribute wind shear loads and dampen differential thermal expansion between dissimilar metals and tempered glass panels, eliminating cosmetic screws and cold bridging in modern building facades.
Why are global OEMs transitioning their adhesive supply chains to Guangdong manufacturers? The Pearl River Delta provides an unmatched industrial convergence of upstream monomer synthesis, specialized polymer compounding, precision die-cutting equipment, and direct multimodal logistics.
Huayuan operates complementary production hubs: our primary facility in Nanping Science & Technology Park (Zhuhai) and our high-volume coating complex in Tanzhou Town (Zhongshan). This dual-plant architecture guarantees production continuity and fault-tolerant scheduling.
Equipped with imported high-speed slitting lines, automated log-roll rewinders, and optical CCD die-cut presses. Custom slit widths (from 2mm to 1260mm) and die-cut prototypes based on customer CAD/DXF drawings are prepared in 24–48 hours.
By synthesizing tackifying resins and silicone functional polymers in-house, we eliminate intermediate distributor markups. International procurement teams routinely realize 30% to 50% direct material cost savings over legacy brands without sacrificing quality.
As semiconductor architectures approach sub-2nm nodes and EV battery chemistry migrates to solid-state electrolytes, thermal interface tapes must adapt. Our engineering roadmap prioritizes sustainability, nano-composite dissipation, and volatile-free chemistry.
Phasing out toluene and MEK solvents. Implementing 100% solid-content UV-curable acrylics and hot-melt silicone technologies to comply with upcoming European net-zero and carbon footprint directives.
Infusing isotropic hexagonal boron nitride micro-platelets into polyimide carriers. Achieving thermal conductivity exceeding 3.0 W/m·K while maintaining high breakdown dielectric strength (>8 kV/mil).
Targeted for deep-space avionics, wafer-level vacuum chambers, and LiDAR sensor cavities. Meets NASA SP-R-0022A standards with near-zero condensable volatile materials (CVCM < 0.05%).
Customizing differential release liners (fluorosilicone vs. PET liners) optimized for ultra-high-speed SMT pick-and-place feeders and reel-to-reel automatic taping machines without liner tear or webbing.
We understand that tape failure in a mission-critical assembly can jeopardize multi-million-dollar production batches. Huayuan enforces an uncompromising Quality Management System across every linear meter coated.
Full-process traceability audited annually. From incoming chemical verification (FTIR spectroscopy, viscosity tracking) to multi-zone drying oven temperature control, every mother jumbo roll is cataloged with lifetime retention samples.
Recognized by Underwriters Laboratories under Category OANZ2. Our flame-retardant electrical tapes self-extinguish within seconds upon flame removal, emitting no toxic corrosive halogens.
100% compliant with EU Directive 2011/65/EU (RoHS 2.0) and Candidate List of Substances of Very High Concern (SVHC 235+ substances). Independent third-party test reports from SGS are refreshed and verified annually.
